LiveviewPlaybackSettings

IMPORTANT:

1. Before operating the NVR, make sure you have properly installed hard drives and configured the storage volumes. Otherwise, you will not be able to operate or try some of the system's functionality.
2. Since the NVR system comes with 32-bit plug-ins for screen control, if your PC runs a default 64-bit IE browser and you manually enter the NVR's address on the browser, your browser session may malfunction. Instead, if you double-click on the discovered NVR on the IW2 utility, a 32-bit IE browser will open.
3. When you log in to the Liveview or Playback interface to stream a live or recorded video, install the ActiveX plug-ins. If it does not prompt when you log in, install plug-ins when you try to playback a recorded video. You may then need to re-start the IE browser console.

2-2. Graphical Layout and Screen Elements - Liveview

Once you log in, the system defaults to the Liveview page, which provides access to other configuration utilities, live view screen, and other functional panels. The screen elements are described as follows:

Item Name Description
1	Camera List Provides a glimpse of all cameras inserted into your configuration. Basic information is also provided along with a screenshot.
2	Layout Provides access to various layouts
3	Layout contents	Provides functions to extend, rotate, redo the layout, and control a DI/DO panel.
4	Logo & Menu	Provides access to thePlayback and System Settings utilities, as well as system time and logout function.
5	View cell panel Displays video streams from one or multiple cameras. Snapshot, streaming, bookmark, and audio control functions are also available on individual view cells.
6	PTZ panel Exerts Plan/Tilt control on a selected view cell if the camera comes with mechanical PTZ mechanism. Note that the use of joystick is currently not available.
7	Alarm panel	Reports alarms transmitted via cameras' DI connections or those by the Motion Detection, etc.

Each panel will be described in further discussions.

2-2-1. Camera List Panel

The camera list displays the 16 recruited cameras by the sequential numbering order you configured in the System Settings utility.

Depending on the size and screen resolution of your monitor, the snapshots of 5 or 9 cameras are displayed in this panel, and you should use the Page switcher buttons to see the rest of the cameras. If a user logged in using a credential of a limited access, he may only see cameras that he can access instead of all of the cameras.

To arrange a view cell layout, users can click and drag a camera to a view cell. Once connected, a camera's video stream is displayed.

Camera Thumbnail:

A mouse click on the camera name under the thumbnail brings forth the summary of IP address, model name, recording setup and DI/DO information.

* Snapshot: the camera's image snapshot is replenished every 5 minutes. If a camera is disconnected, the last image taken will be used to represent a camera.

* Camera index & Camera name: Placing the mouse cursor on top of a camera text displays the camera index number and the camera name. You can click on the camera index to display the information box.

* Status:

	Online: the online status can be accompanied by the DI/DO icon 🎨 🎩
	Offline: camera is disconnected.
	An unconfigured camera instance
	Digital input is triggered
	Connected and recording video to system storage
	Connected with live streaming
	Disconnected or trying to establish a connection

* Page switcher: Moves to the next page on the Camera list panel. The button will be grayed-out if the end of the list is reached.

Sorting criteria

Use the sorting buttons to re-arrange the order of the cameras on the list. Cameras that match the condition will be brought to higher places on the list (front of the order) regardless of its original camera index.

	Online: the online cameras.
	Offline: the offline cameras.
	Unconfigured camera instance
	Cameras whose Digital inputs have been triggered
	Cameras whose Digital outputs have been triggered

NOTE:

For online cameras, the snapshots on the camera list are refreshed by every 5 minutes, and therefore may not represent the latest occurrences on the surveillance areas.

2-2-2. Layout

By default, 5 typical layouts are provided for the user. They include: 1x1, 1+3, 2x2, 1+5, and 4x4. System default is the 4x4 layout. Cameras that do not fit into the first page of a layout, say, a 2x2 layout, will be displayed on the succeeding layout pages.

Each functional button on the screen is activated by a mouse hover. For example, the below states designate user's operation on a button:

1. : not selected.
2. : moused over, and is ready for selection.
3. : selected, and is taking effects.

Because the maximum number of supported cameras is 16, the fifth and sixth view cells on the 3rd page of the 1+5 configuration will be unuseful.

Only an administrator can change and preserve a custom layout, and every user can designate a specific layout to be displayed when he/she logs in. The default layout for each user is stored in a browser's cookies.

Whenever changes are made to the current layout, a message prompt will appear on the side of the layout panel reminding you to save your current setting.

Note that a user who did not log in as an administrator can change a layout, but his configuration changes (with cameras inserted into view cells) will not be saved.

User Layouts

There are another 4 user layouts that can be individually configured. An administrator can insert camera views into these layouts, and save the configuration. These user layouts can be seen by all users.

If you click the Rotate button before the configuration changes can be saved, your configuration changes will be lost.

2-2-3. Layout contents

A few functional buttons are available on the Layout contents page.

	Clears all view cells on the current layout
	Full view: extends the view cells on the current layout to the full of the screen.
	Rotate: the rotate function lets system display successive layout pages by the intervals of 10 seconds. The layout page that does not contain camera views will be skipped.A Rotate action will stop when you1. move to another page,2. move to a user layout,3. click to select a view cell,4. remove a camera from view cell.
	DI/DO: displays the DI connection statuses and allows users to manually trigger a DO signal.
		If your current layout spans across multiple pages, use the arrow buttons to switch from one page to another. The index number of the current page will be shown between the arrow buttons.

When your current layout is displayed in a full view, move your cursor to the left center of the screen to return to the default Liveview screen. The Return button will appear.

2-2-4. Logo & Menu

A logout button, system time panel 1, and 3 hot link buttons to access the Liveview, Playback, and System Settings utilities.

Three black square icons with white symbols: eye, clapperboard, and gear on dark background (no text or labels)

The system date and time refers to the date and time kept on the NVR system's real time clock.

Due to the limited space for the user name, user name may be partially displayed until you hover your mouse cursor.

IMPORTANT:

Your configuration changes will be lost if you click one of the hot link buttons to move to another utility window. For example, you have changed your Live View layout and then click on the Playback button, you will enter the Playback window without saving your configuration. Save your changes before you use these buttons.

2-2-5. View Cell panel

A single view cell is shown below. Each view cell contains a video stream display area, an information bar, and functional buttons at the bottom. A view cell is displayed in Normal, Focused, or Maximized mode.

1. A single click selects a view cell from the View Cell panel, enables its function buttons, and turn it into the Focused mode.
2. The 2nd click maximizes the size of the view cell to the full of the panel.
3. The 3rd click shrinks the maximized view back into the focused mode.

To deselect a view cell and return to the normal view, click on the Restore button at the lower right of the window.

Adding Cameras to View Cells

1. Click and drag a camera from the camera list to an unoccupied view cell.
2. Double-click a camera on the camera list. The camera will be added to the first unoccupied view cell.

To deselect a view cell and return to the normal view, click on the Restore button at the lower right of the window. You can also click on another view cell to continue adding other cameras.

Close-up of a hand pointing at a diagonal line on a textured surface, with control buttons below (no readable text or symbols)

A view cell attempting to connect to a network camera will look like this. If the connection attempt takes a long time, it may result from network problems or incorrect configuration with video streaming. For example, you may have configured the camera to be streaming channel #2 using the MJPEG mode, which is not supported by the system. The NVR uses video stream #1 for recording, and stream #2 from cameras for live viewing. You should then open an individual web console with the network camera to change its video streaming configuration.

IMPORTANT:

A camera can be inserted into multiple view cells. This way, a camera with a wide field of view, such as a fisheye camera, can simultaneously display different regions of interest in different view cells.

If the current layout already contain 16 cameras, the following message will prompt.

Not able to add camera Current layout already has 16 cameras.

There can be more than 16 view cells across multiple layout pages, e.g., on the third page of the 1+5 layout. Placing a camera in the 17th or 18th view cell will bring out the following message.

Not able to add camera Could not place camera here. Try other view cells.

Tool Bar Functions in Details

1. Play and Pause buttons:

These buttons pause and resume a video stream currently being played on your web browser. Note that this operation does not affect the video recording taking place between a camera and the NVR system.

2. Bookmark:

This function allows you to place a bookmark on a recorded stream when you observe a situation from your live view window. The bookmark is preserved as a one-minute footage along with a short description of a particular incident. The precondition of using this function is that the video stream, while you are watching it on the view cell, must be recorded to the NVR at the same time.

To add a bookmark,

1. Click on the button,
2. Enter a short description that can be as long as 120 characters.

1. A confirm message will prompt at the lower right of the screen.

If the current video feed is not being recorded to storage, you will receive the following message:

Errors with creating bookmarks may also result from network and server errors.

Below are two bookmarks (yellow tags) shown along with a recorded video in the Playback utility screen. Bookmarks help find and retrieve important moments in a recoded video.

NOTE:

Bookmarks will be erased if the user/system erases the video clips they were appended to. For example, system will recycle storage space by deleting old videos along with their bookmarks.

3. Snapshot:

This button produces a snapshot prompt. You may then right-click on the snapshot image to save it to a preferred location.

Note that the size of a snapshot is equal to the frame size set for the video stream.

4. Clear:

This button removes camera from the current view cell. The view cell will then be available for other cameras

5. Mute and Unmute:

These buttons stops or resumes audio from a live stream.

6. Restore:

This button restores the view cell's original position on the Liveview panel.

7. Maximize:

This button extends the size of current view cell to the full of the Liveview panel.

8. Activate and Deactivate PiP function:

PiP is short for Picture in Picture, a function that provides digital zoom into a live video. When activated, a Global view window will appear at the lower right of the view cell as shown below. You can display only a portion of the complete video frame as an area of your interest. Using a click and drag on the ROI window, you can instantly move to other areas within the video frame.

You can resize the ROI window by a mouse hover on the lower-right corner of the window until the resize mark appears. The default size of the ROI window is 25% of the Global view.

Click on the deactivate button to close the PiP window.

Note that not every camera supports the PiP function. For example, the fisheye series cameras do not support this feature.

NOTE:

The Talk function in the two-way audio is currently not supported.

9. Volume controller:

The volume control takes effect when audio input from the network camera is available. Audio is heard only from a focused window, one that you selected by a mouse click form the Liveview panel. Some network cameras do not come with an embedded microphone, and its audio is disabled by system default. The actual sound level is also dependent on the system volume of the PC having a web console with the NVR.

The sound volume configuration will not be preserved when a camera is removed from a view cell, web console is restarted, or when the Liveview layout is re-configured.

10. Fisheye display modes:

A view mode selector icon appears in a view cell of a fisheye camera. You can click to select a viewing mode. The viewing modes are illustrated as follows:

10 (Original view)

10 View (Original View)

1P (Panoramic view)

    U --> V["Arrow to bottom"]
    V --> W["Arrow to bottom"]
    W --> X["Arrow to bottom"]
    X --> Y["Arrow to bottom"]
    Y --> Z["Arrow to bottom"]

1R (Regional view)

The 1R mode (or rectilinear) provides access to one image section within the hemisphere. You can zoom in or out (using the mouse wheel or PTZ panel) or travel through to other areas within the hemisphere using simple mouse clicks and drags. A single click on a particular object can bring the object to the center of your view window. Click and hold down the left mouse button, and you can swipe the view both horizontally and vertically.

Note that if your fisheye mounting type is set to the Wall Mount type, your screen control in the view cell will be limited to 90^ pan and tilt. Make sure your mounting type and camera settings have been properly configured.

Because fisheye lens can cover a wide surveillance area, you can insert a fisheye camera into multiple view cells, and let different regional views display in these view cells. In this way, you can have a glimpse of multiple areas of interest, and the configuration of these different view windows will be preserved when you save your layout settings.

2-2-6. PTZ panel

The PTZ panel takes effect for cameras that come with mechanical PTZ functions. It does not support digital PTZ functions. To utilize its functions, select a view cell populated by a PTZ camera, such as a speed dome.

Depending on the individual functions that come with PTZ cameras, some functions will not be available for every cameras. For example, the zoom controller will not apply for a PTZ camera that comes without a mechanized zoom module, such as PD8136 and PT8133.

Listed below are the camera models and the types of supported PTZ controls:

Model (series)	Pan/tilt controller	Preset location	Zoom controller Focus	us controller Auto	Pan/Patrol controller
PT Yes Yes No No	Yes
VS (VS8102 and earlier)	* Depends Depends	Depends Depends	No
VS84xx/88xx Depends	Depends Depends	Depends Depends	Depends
PZ series Yes Yes	Yes Yes Yes
SD8xxx	Yes Yes Yes Yes Yes
SD7xxx Yes Yes Yes	Yes Yes Yes
IP7xxx/8xxx box camera	Depends Depends	Depends Depends	Depends
IP6xxx/3xxx/2xxx box camera	No No No No No
IZ series	Depends Depends	Yes Yes Depends

* If the analogue cameras connected through the video server support PTZ mechanism.

NOTE:

On the the Liveview window, currently the Continuous Move and the Click-on-image functions for PTZ cameras are not supported. Neither can you zoom in/out using the mouse wheel.

PTZ presets: If your PTZ cameras have preset locations, click on the button to unfold the preset menu. Click on any of the preset locations to move to the area of your interest. Refer to your camera's User Manual for how to configure preset locations.

The following message will prompt if the camera has no preset locations.

Pan/Tilt controller: A mouse hover over the arrow buttons activates the arrow button. Use the buttons to navigate to a preferred location.

Zoom controller: The zoom controller buttons only apply to cameras that come with an optical zoom module, such as a speed dome camera.

Focus controller: The focus controller buttons apply to cameras that come with focus control over its lens module, such as a speed dome camera.

Auto Focus: If your camera supports the auto focus function, use this button to acquire an optimal focus point.

Auto pan/patrol controller: These buttons provides pan and patrol functions provides that preset locations have been configured on the camera. For a speed dome camera, the pan command tells the camera to continuously pan 360 degrees until stopped by a user command. For PZ or PT series cameras, the pan action only takes place once to cover reachable areas.

The Stop button ends a pan or patrol tour.

2-2-7. Alarm panel

To receive alarms from cameras, you need to configure alarm triggers in the Settings > Alarm configuration window (see page 99). Network cameras' digital inputs, digital outputs, or motion detection, or NVR's digital inputs can all be used to detect conditions in external environments. When the alarms are triggered, you can configure certain kind of actions to take place in response to the alarms, such as:

1. recording the immediate video,
2. sending an Email,
3. sounding the buzzer,
   4, sending snapshots to an FTP server,
4. sending event messages to web server,
5. moving camera lens to a preset location,
6. triggering an NVR/camera digital output.

The alarm panel displays the latest 10 alarm entries with the latest alarm on top of the list. The alarm list keeps up to 200 events. Older events will be erased if the number exceeds 200.

The alarm panel is polled every 10 seconds. A mouse hover on an alarm entry displays full information of the event.

Note that multiple alarms can be triggered by one incident. See page 99 for how to configure the alarm settings.

The alarm panel is displayed either in the list mode or the icon mode.

e icon mode .

If an event is configured with a recording action, or the alarm is triggered when the associated camera was recording to the NVR, there will be a play button to the left of the alarm message.

The alarm playback window will begin playback of footage from 10 seconds before the alarm. The playback of an alarm-triggered recording will normally last for one minute. If, however, you configured a shorter pre- and post-alarm recording time, your alarm recording may be slightly shorter. The defaults for pre- and post-alarm buffer time are 5 seconds and 20 seconds.

Click and read a text-only alarm will turn off the alarm icon. The alarm icons indicate unread alarms. The number of unread alarms will be listed on the title bar.

You can click on the icon mode button to have a glimpse of alarms indicated by their snapshots taken by the time of the occurrences. If the alarm is triggered by NVR DI pins, no snapshots will be available.

Move your cursor over an alarm with a recorded footage. The Play button will become available.

The following buttons are available in the alarm playback window.

Buttons Description
	View live video: displays the live view streaming instead of the alarm recording.
	Resumes the alarm playback.
	Begins the alarm playback.
	Pauses the current playback.
		Mute or unmute the audio with the current playback. Drag the controller to change the audio volume level.
		Use the playback slider to quickly change the playback position.

Incoming Alarms

New alarms will be indicated by the messages in bold letters, the alarm bell icons, and the increasing number of unread messages 3 on the title bar.

A text-based history of past Alarms is accessed through the Alarm - History page in the Settings window. See page 110 for information.

2-3. Graphical Layout and Screen Elements - Playback

The screen elements of the Playback window are described as follows:

Item Name Description
1	Camera List Provides a glimpse of all cameras that have recorded data. Basic information is also provided along with a screenshot.
2	Layout contents Provides functions to extend, rotate, redo the layout, and for synchronous playback.
3	Logo & Menu	Provides access to thePlayback and System Settings utilities, as well as system time and logout function.
4	Playback panel Displays the playback functions. Snapshot, bookmark, and export functions are also available on individual view cells.
5	Alarm panel	Reports alarms transmitted via cameras' DI connections or those by the Motion Detection, etc.
6	Calendar	Shows when the recording took place, and thus enables users to quickly locate a specific part of recording in history.

2-3-1. Camera List Panel

The camera list displays the 16 recruited cameras by the sequential numbering order you configured in the System Settings window. The elements in the Camera list on a Playback window are identical to those on a Liveview window. Please refer to page 30 for details on the Camera list panel.

There are two key differences between the Camera List on Liveview and that on the Playback window:

1. Users can not click and drag a camera thumbnail to a playback view cell.
2. A double-click on a camera does not display video in a view cell. A double-click displays a calendar where days with recorded videos are shown.

To begin playback and search for past recordings,

1. Double-click on a camera.
2. The Calendar panel will display the days video recording actually took place. And those days will be highlighted by a blue background (as the 25th and 28th in the screen below.)

2-3-2. Playback Layout

3 types of layouts are provided for the Playback window. They include: 1x1, 2x2, and 1+3.

In the playback window, users can simultaneously playback up to 4 recorded videos.

		Clears all view cells on the current layout
		Starts or stops the Synchronous playback.
		Full view: extends the view cells on the current layout to the full of the screen.

When your current layout is displayed in a full view, move your cursor to the left center of the screen to return to the default Liveview screen. The Return button will appear.

2-3-3. Logo & Menu

A logout button, system time panel and 3 hot link buttons to access the Liveview, Playback, and System Settings utilities. This panel is identical to that on the Liveview window.

2-3-4. Playback View Cells

The view cells in Liveview and Playback windows are similar. Their differences are listed as follows:

1. 3 simple layout types are supported as previously discussed.
2. The information bar displays camera index and video time information only.
3. The Play and Pause buttons are not available on the Tool bar. One Export function is added on a Playback view cell.

The functional buttons on an individual view cell are described as follows:

Buttons Description
		Exports a section of the video into a 3GP or Windows exe file. The length of exported video is configurable to 1, 3, 5, or 10 minutes.
		Adds a Bookmark (that saves a short description and a one-minute footage from the current feed)
		Takes a snapshot.
		Removes camera from the view cell.
		Mutes (if there is audio input from the camera.)
		Unmutes
		Restores the view cell's original position on the liveview panel.
		Maximizes the size of current view cell.
		Activates the PiP function.
		Disables digital zoom (PiP).
		Volume controller
		Fisheye viewing modes - if the view cell contains video from a fisheye camera, the fisheye display mode selector will be available:1O: the original circular view.1P: the panoramic view.1R: the regional view.Please refer to the fisheye camera's User Manual for more information.

Playback control panel

The time slide bar enables quick skimming through the recording. Its functional buttons are described as follows:

Buttons Description
		Pause
		Play. This button is available after you manually paused a playback.
		Stops the current playback.
		Next frame. After you paused a playback, use this button to browse video frame by frame.
		Speeds down by 1/2. The slowest speed is 1/8.
		Speeds up. Increases the playback speed, to 2x, 4x, 8x, 16x, 32x, and then to a maximum of 64x.
Playing 4 x		Displays the current playback status, such as Playing, Pause, or Stop.
		Restores the view cell's original position on the liveview panel.
		Maximizes the size of current view cell.
		Activates the PiP function.
		Disables digital zoom (PiP).
		Timeline zoomer. Use the zoomer to zoom in for more precise skimming.
	Timeline slider thumb. Click and drag this thumb button to move along and reach a specific point in time. A click on the time line will also work.

The time line shows the length of existing recording taken on a specific time span. You can use the timeline zoomer to scale down the span of time. For example, if the time span is reduced to 1 hour, then each section on the time line represents 15 minutes of recording. The total time span of a timeline starts from the minimal of 4 minutes, 20 minutes, 40 minutes, 1 hour, and up to a maximum of 24 hours.

In Synchronous play mode, a change to the zoomer will be reflected by all synchronously playing view cells.

If recordings take place by an event-triggered recording, the intervals between recordings can be down to 1 minute, and the individual recordings will not be easily discernible. In this situation, you can mouse over the timeline to pinpoint individual recording instances.

2-3-5. Alarm Panel

The alarm panel displays the alarms or bookmarks recorded by the day of recording. Two additional buttons are available: Page selector and Alarm filter.

See page 99 for how to configure alarms.

• A playback button will be available with an alarm-triggered recording. The alarm panel in the Playback window also supports the List mode and Icon mode that are similar to that in the Liveview window.
• There can be numerous alarms occurring in a day. Use the page selector to display different pages of alarm entries. Up to 200 entries can appear on one page. Note that the new alarms that occurred seconds or minutes ago may not be instantaneously listed on the page.

If bookmarks are listed in the Alarm list, a bookmark entry will look like this:

Camera index. camera name (time) - bookmark

In the icon mode, a bookmark message will look like this:

Camera index. camera name bookmark, time of marking

Alarm filter:

Use the Alarm filter to find out specific alarms. Use the check circles below to narrow down your search criteria by Alarm name, alarm type by Motion detection, DI, DO, or those manually marked down as Bookmarks.

The alarm name is defined by users in the Settings > Alarm page.

2-3-6. Calendar Panel

Double-click on any of the existing cameras to display the Calendar panel. Days with recorded videos will be highlighted in blue regardless of the length of existing recordings that occurred in that day. You may then click on a day to begin viewing the past recordings.

You may use the arrow button to view the records in other months. If there are no recordings in the current month, the recordings taken in the days of the following month will be shown steady.

3-1-1. System - General

The system general information window allows you to change the system host name, time zone, system date and time, and set up a scheduled reboot of the system.

Note that if NTP time server configuration is preferred, you should configure all of your cameras to listen to the same time server as those shown in the pull-down menu. You need to configure camera settings over a web console, and set up the same configuration in the System >

General settings > System time page. The precondition is that the system must have access to the Internet.

The Schedule reboot device allows the system to clean up dirty cache by a scheduled reboot. You can configure a reboot by a specific time within a week. Note that during the reboot the video recording will be temporarily interrupted.

Scheduled reboot is an recurring event. Select the day within a week and a time for the reboot using the checkboxes and drop-down menus.

3-1-2. System - Upgrade

If the need arises for updating system firmware, acquire the update from VIVOTEK's technical support or download site. Locate the firmware binaries, and click Upgrade. The upgrade should take several minutes to complete. Note that during the upgrade, the recording task will be interrupted.

3-1-3. System - Backup

On this window, you can perform 3 maintenance tasks:

1. Backup - You can backup your system configuration using the Backup function. Click Backup, a message window will prompt. Click Save to preserve your system configurations.

Select a location for your backup file, then click Save to complete the process.

Note that the backup action does not involve the following:

1. Recorded videos and database,

2. Alarm records, bookmarks, and bookmarked footages.

3. Restore - If you have a previously-saved profile, you can restore your previous configuration. Click the Restore button.

A file location window will prompt. Location the backup file, and click Open. The Restore process will take several minutes to complete, and system operation will be interrupted during the process.

1. Restore Default - There are two kinds of defaults for the NVR systems: System defaults and factory defaults.

The system defaults can be restored using the pushbutton on the system front panel. This applies when users forget about its IP address or login password, while most other operation details will remain unchanged.

The factory defaults (operated on this window) restores to its primitive state before shipping, and hence users' configurations (such as host name, IP address, and layout settings) will be erased.

Click Restore to restore your system defaults. A warning message will appear. Click OK to proceed. The Restore process will take several minutes to complete, and system operation will be interrupted during the process.

A successful operation will produce the following message.

Restore completed

When Restoring the previous backup, the following should be noticed in terms of storage configurations:

1. If storage configuration has not been changed, restoring configuration will not affect the current storage configuration.
2. If changes have been made to storage configuration, the backup-restore action will not displace the current storage configuration.
3. If users removed the current storage configuration, no storage volumes will be restored after a backup-restore procedure. Users then must create new storage volumes to proceed with recording tasks.
4. If users apply previous backup to a new NVR machine, system will detect the presence of different hard disks, and no storage configuration from the backup file will apply.
5. If users move all hard disks and backup file from an NVR to another, storage configurations will be stored on the new machine.

3-1-4. System - Maintenance

This window displays basic information of various aspects, including CPU and memory usage, LAN port operation and its bonding, disk drive temperatures, and UPS status.

System - Maintenance

The Reboot button is used to restart the NVR system.

The Reboot process will take about 2 minutes to complete.

The Refresh button polls the system for the latest system information as previously described.

Pressing the Shutdown button will power off the NVR system. System will flush its cached contents, and stop the recording and streaming tasks.

UPS support

Once an UPS is connected via the USB interface, the NVR system supports the cooperating protection against power outage. The UPS status [model name, status (Online or On battery), battery charge level] is listed in the Maintenance page as shown below.

The NVR supports APC's Back-UPS and Back-UPS Pro series models.

Reactions on power outage:

When the UPS battery charge is lower than 10%, or can only sustain system operation for 3 minutes, the NVR system will automatically shut down. When the power source is restored, the NVR system will automatically power up.

3-1-5. System - DI and DO

This window displays the digital input and output settings for the connections via the system's terminal block. You can connect the sensor devices (such as a PIR sensor) to the terminal block. The system will automatically detect the current connection as a high or low signal. You can then define the normal status for the input or output pins.

1-1. Failover - failover provides the capability to transfer network traffic through the surviving LAN port if any of the two LAN ports is disconnected.
1-2. Load balance - Based on 802.3ad, Load balance enables two LAN ports to share the load of network traffic. Non-layer 3 traffic, such as Multicast/boardcast requests will be transmitted via one of the LAN ports. To best utilize this feature, you should use a managed Gigabit Ethernet switch and have its 802.3ad link aggregation feature enabled on the corresponding ports.
1-3. Standalone - When selected, different IPs will be assigned for each LAN port. The NVR can be accessed via different subnets.

You may connect these ports to different subnets. For example, LAN1 to a router and have the access to the Internet; and LAN2 to a private subnet. In this case, however, you should appoint LAN1 as the default routing interface, so that Internet access is available for DDNS settings or remote access.

3-2-3. Network - Service

By default, the NVR service and video streaming are accessed via HTTP port 80 and RTSP port 554. You can designate a different port number if the need arises. Usually it is not necessary to change these ports.

Network - Service

Instead of a web console, you can also access the NVR and the subordinate cameras using the iViewer and VIVOTEK's VAST software. The NVR can be managed as one of the sub-stations in a hierarchical device structure.

Note that the password here should be identical to that you use to log in to a VAST server. For iViewer, you log in using the same user name and password for the login to the NVR.

3-3. Camera

3-3-1. Camera - General

The camera window provides management tools to recruit or disband cameras from your NVR configuration.

Camera - General

1. Search:

The Search button allows you to locate all VIVOTEK cameras within a local network. Use the check circles on top to display all cameras or only cameras that have not been recruited.

On a listed camera, mouse over to the left of the entry to display the Add button. Click on the button. To deselect a camera, use the Remove button.

+/-	#	MAC address	IP address	Channel	Model	Port
+		00:02:D1:1A:A9:AD	192.168.4.108	1	FD8161	80
		00:02:D1:1E:3D:3B	192.168.4.157	1	FD8163	80

Select a camera index number from the pull-down menu. The first unused number will be listed. You may also select a different number or a number already appointed to another camera. However, doing so will replace the existing camera.

+/-	#	MAC address	IP address	Channel	Model	Port
	5	00:02:D1:1E:3D:3B	192.168.4.157	1	FD8163	80
		00:AB:CD:AB:CD:EF	192.168.4.147	1	PD8136	80

Repeat this process to select more cameras in your deployment, and then click the OK button.

IMPORTANT:

If you select an index number already appointed to an existing camera for a new camera, the recorded data taken from the existing camera will still be intact. However, the recorded data is accessed through the same index number but using the name of the new camera.

The legends used in the camera list are described below:

(*) asterisk: An asterisk symbol indicates that a camera's settings have been modified.
(#) numbered: Camera index.

Name: Camera name.

IP address: A valid camera configuration enables the IP address as a hyper link. You can click on the hyper link to open an IE web console with the camera.

MAC address: A unique MAC address as that printed on the camera's label.

Model: Camera model name.

Channel: This indicates the stream number. If connected via a video server, the channel number indicates the channel through which an analogue camera is connected.

A recent snapshot from the camera will also appear at the bottom of the camera list window.

Left-click to select a camera, and edit the Connection and Recording configuration below:

1. Connection - You can rename the camera, and if your camera comes with password protection, enter its User name and Password here. Otherwise, you will not be able to manage or access the camera.

If preferred, the acceptable characters for a new camera name can be: [0-9][a-z][A-Z][_][-]\$. The max. number of alphabetic and numeric characters is 64.

For a user name, the acceptable characters for a camera name can be: [0-9][a-z][A-Z][_][^][-][.][@][\~][!][\$][%]. The max. number of characters is 64.

2. Recording:

2-1. Keep all recordings for maximum * days - determine the life span of recordings in your system. Usually old recordings will be erased when the storage volumes become full. When a storage volume is 90% full, the recorded videos taken on the oldest day (from every camera) will be erased. Deletion of old files will stop when the used space falls under 85% again.

When recycling takes place, the system buzzer will be triggered, and the recording task can be halted temporarily until more storage space is regained.

2-2. Pre-alarm buffer time (seconds) - if the alarm-triggered recording is preferred, set up a pre-alarm buffer for the system to record video before the occurrence of an alarm. The configurable options are 3, 5, 10, 15, and 20 seconds. A 20MB memory space is reserved for each camera, and therefore the pre-alarm buffer time can be shorter if the camera video is recorded using a higher resolution.
2-3. Post-alarm buffer time (seconds) - if the alarm-triggered recording is preferred, set up a length of time for the system to record video after the occurrence of an alarm. The configurable options are: 10, 20, 30, 40, and 60 seconds.
2-4. Enable audio recording - Selected by default. Audio input is also recorded along with the video. However, audio can be muted by default on some cameras. For example, a speed dome camera requires the connection to an external microphone, and the audio function is manually turned on through a management session with the camera.
2-5. Enable manual recording - If this checkbox is deselected, you will not be able to enable or disable manual recording from the Liveview view cells.

3. Delete:

To remove a camera from your list, left-click to select a camera on the list, and then click the Delete button.

Note that once a camera is removed, all alarm settings related to the camera, such as DO and preset location settings, will be erased.

3-3-2. Camera - Video

The Video page determines the Liveview and recording streams of individual cameras in terms of compression format, video resolutions, frame rate, and the constant bit rate settings.

The constant bit rate setting is especially important in that the sum of bandwidth consumed for all recording streams must not exceed the 96Mbps threshold. The constant bit rate is like an upper threshold placed on each video stream. The size of IP packets delivered from the network camera will be maintained within the bit rate limitation.

If you configured a RAID5 volume as recording storage, the bandwidth threshold will be 48Mbps.

1. Video compression: The supported formats are: MPEG-4, H.264, and SVC. The MJPEG format is not supported. If you change the bit rate and resolution settings of a camera, the configuration applies to the camera firmware settings on its individual video stream. If a camera becomes disconnected, your configuration change will not take effect until the camera come online again.
2. Video resolution: The applicable video resolutions comes available in a pull-down menu. For different cameras, the applicable resolutions can vary.
3. Frame rate: The applicable frame rate also varies from camera to camera. The list of applicable frame rates is polled from individual cameras.
4. Constant bit rate: This places an upper threshold to limit the bandwidths consumed for live viewing and recording streams. If "---" (not available) is shown, your camera stream might have been configured using a "fixed quality" setting. You may need to open a web console with it to convert the camera stream to be using the constant bit rate setting.

3-3-3. Camera - Schedule

The camera recording schedule can be configured down to an hourly basis. The default settings for cameras is to record videos at all time.

To set up a schedule,

1. Select a camera from the list using a single mouse click,
2. By default, all days and hours will be selected for continuous recording. If you want to disable recording for specific time during a week, or enable event-triggered recording during some time, use the Event recording and No recording buttons. Use them as a paint brush or eraser on the weekly time chart. Click or drag your mouse cursor across the time chart to change the recording schedule.

Change a non-recording hour to continuous recording by one click on the Continuous recording button and then click and/or drag on the time chart.

The color codes for the display on the time chart are shown below:

Continuous recording
Event recording
No recording

The Event recording is triggered by digital inputs or motion detection. You can click on the setup button to select or deselect the triggering options.

3-4. Storage

3-4-1. Storage - Volume

With up to 4 disk drives, you have the following options for configuring storage volumes:

1. Single disk: The single disk configuration provides no fault tolerance. The system stores video recordings to one or more single disk volumes in a consecutive order.

Disk 0 Disk 1 Disk 2

Each single disk volume contains one disk drive.

1. RAID0: A RAID0 volume spreads data blocks of each file across multiple disk drives. The volume provides no redundancy. RAID0 provides high performance by simultaneously reading or writing to disk drives, but if a drive fails, all data within is lost. Select at least 2 disks to build a RAID0 volume.

Disk 0 Disk 1 Disk 2

1. RAID1: A RAID1 volume provides high fault tolerance by writing the same data blocks simultaneously to duplicate disks. Select at least 2 disks (or 4 disks) to build a RAID1 volume.

    A["RAID1"] -->|Mirror| B["RAID1"]
    subgraph RAID1
        A1["A"] --> A2["B"] --> A3["C"] --> A4["D"] --> A5["E"] --> A6["F"] --> A7["G"] --> A8["H"]

        E --> E1["EFGHIJKLMNOPQR"]
        E1 --> E2["N/A = Parity block"]
    end

1. RAID5: A RAID5 volume provides a balance in performance and good fault tolerance. RAID5 stripes data and also generates error correction information (parity bits). One drive's capacity is needed to store the error correction information from all member drives. A RAID5 volume requires at least 3 disk drives.

Note that if a member drive fails, the rebuild process of a RAID5 volume can take about several days to complete (using 2TB drive members). The rebuild runs in the background, and the rebuild progress is indicated on the volume page.

Disk 0 Disk 1 Disk 2

On this configuration window, a "disk" refers to a physical disk drive, a "volume" refers to the logical configuration of disk drives which may include multiple disk drives.

IMPORTANT:

If you remove a disk drive and insert it into a different drive bay, the system will consider it as a new and different disk drive.
Some of the RAID levels provide data protection. Below is the summary of RAID level features:

RAID level No. of HDD No. of			HDD failure Allowed	Capacity
RAID0 2 0 HDD # x (smallest HDD size)
RAID1 2 - 4 1 or 2 (if counterparts in the mirrored pair survives)				HDD # / 2
RAID5 3 1 (HD # - 1) x (smallest HDD size)

The legends used in the Volume list are described below:

*	#	Disk	RAID	Total size	Available size	Status	Selected
	1	Disk 1, Disk 2	RAID 0	294.3GB	294.1GB	Online
	3	Disk 3	Single disk	2775.0GB	2258.2GB	Online

(*) asterisk: An asterisk symbol indicates that a volume's settings have been modified.

(#) numbered: Volume index.

Name: Volume name.

Disk: Member(s) of this volume.

RAID: The RAID level by which this volume was made.

Total size: Total usable capacity size in Gigabytes.

Available size: The unused capacity in Gigabytes.

Status: The statuses can be: New, Online, Offline, Processing, Disabled, Error.

New: Individual disk drives have not been configured into usable storage volumes.

Online: The volume is ready.

Offline: A volume that has fatally failed, or its member drives are missing. Buzzer will be sounded if a volume goes offline. Its sizes will then be indicated as unknown, "---."

Processing: A storage volume configuration is being processed.

Disabled: This volume has been disabled by users.

Error: Configuration or hard drive errors. The volume is invalid, and may need to be manually removed.

Enable volume: It takes several seconds to disable a volume for the need to inform running software and services and flushing cached contents.

Enable volume

To create a storage volume:

1. Click on the Create... button. Also check that if all your disk drives are listed. If properly installed, they should all be listed in the Storage - Volume window.

Storage - Volume

IMPORTANT:

If you want to delete a RAID5 volume with a spare drive, remove the spare drive before you delete the volume.

To rebuild a storage volume:

The precondition is that you have a fault-tolerant storage volume made in a RAID5 or RAID1 configuration. A faulty drive is indicated by the front panel LED or messages in the system logs. The White Volume LED on the drive tray will be turned off.

IMPORTANT:

Please carefully identify which disk drive has failed. Replacing the wrong drive in a logical volume that already has a failed member will destroy the whole volume.

1. In System > Logs window, make sure which disk drive has failed. The sample screen shows that Disk [3] has failed. A failed drive can sometimes be indicated as a removed drive.

1. Click to select the degraded volume, and then click on the Advance... button.

1. Select the faulty drive to set it as "Faulty." Click OK to proceed.

A failed drive or a drive set as faulty will turn off its LEDs or the White I/O LED is off.

On the Volume screen, faulty disk is indicated.

1. Replace the drive indicated as faulty. Open the bezel lock. Flip the door latch to the side and then pull the bezel lever to remove the drive tray. Remove the HDD from the tray and replace it with a new drive.

Bezel Lock

1. Once the replacement disk is installed, click on the Advance... button again. Select the replacement drive. Click OK to proceed.

During the rebuild process, further configuration of the volume will become unavailable. The recording tasks will continue during the process. The following message will be shown if you want to configure the volume during a rebuild.

1. The rebuild process will start, and its progress is indicated by a progress bar in the Status column.

The rebuild process can last for many hours using today's large capacity disk drives. The rebuild process runs in the background and the recording tasks should continue.

To format a storage volume:

You may also format an existing storage volume in situations such as when you need to re-deploy the system elsewhere.

To add or delete a spare disk:

The spare drive option only appears when,

1. A 3-disk RAID5 volume is available.
2. An unconfigured new drive.

A spare disk (or standby disk) can immediately participate in the rebuild of a RAID5 volume, saving the time for replacing a faulty disk. When in the "one-drive-failed" degraded mode, failing another drive will destroy the volume. Using spare disk can reduce the chance of failing yet another member drive.

To add a spare drive to a RAID5 volume,

1. Left-click to select a RAID5 volume, and then click on the Advance... button.

1. Select the unconfigured drive, disk #4 in this case, and then click on the OK button.

1. The Add Spare process will take 3 to 5 minutes to complete, and the progress is indicated in the progress bar below.

1. On completion, Disk 4 will be listed as a hot spare in the storage volume information.

NOTE:

Since RAID0 has no data protection, if a RAID0 volume has a failed member, the Advanced.. button will not be functional.

3-4-2. Storage - Disk

The Disk window provides access to physical disk information, disk physical location, disk health, polling for S.M.A.R.T. statuses, and bad block check.

(#) numbered:	Disk index. This is determined by their loations in the chassis as shown by the disk location graphics [icon: 2] on the lower right of the screen.
Model: Disk model name.
Capacity: Disk capacity in Gigabytes.
Status: Disk operating status. Can be stated as:
	Connected: Disk is properly installed, but not yet configured into storage volume.
	Identified: The storage volume this disk belongs to is operating normally.
	Corrupted: Disk is faulty.
S.M.A.R.T.:	S.M.A.R.T. status polled from the disk drive. This is not the results from a manually-executed S.M.A.R.T. test.
Progress:	This shows the progress of drive S.M.A.R.T. test or bad block scan.

1. Disk Information:

Model family: The brand name of the HDD manufacturer.

Device model: The disk model name.

Serial number: Serial number assigned to the disk drive.

Firmware version: The version of firmware running on this disk drive.

User capacity: The rated capacity for this disk drive.

Status: The bad block check or S.M.A.R.T. test previously executed on this drive.

2. S.M.A.R.T. test:

Attribute: The various attributes can vary from different HDD manufacturers.

Value: Value for the currently selected attribute.

Worst: Worst value acquired for that attribute.

Threshold: A predefined threshold or triggering value. The threshold below which the normalized value will be considered exceeding specifications.

Raw vaule: The detected parameters for that attribute.

Status: The judgement made to deem the current reading as OK or failed.

3. Check disk:

Three types of check disk actions is initiated through this button. Select the action you wish to take and click the OK button.

Bad block check: Performs read/write test to drive sectors to locate bad blocks. This action may take several hours to complete.

Short test: Tests the electronic and mechanical performance and disk read performance, including those on disk buffer, read head, seek time, and integrity of drive sectors. The short test is performed on a small section of disk platters, and takes about 2 minutes to complete.

Long test: The long test is more thoroughly and is performed to all drive sectors. The actual completion time depends on drive sizes and the attributes put to test.

The Check disk functions mentioned above, when performed during active I/Os, can consume system resources and cause dropped frames with the recording tasks.

4. Stop check disk:

Stops the bad block check or S.M.A.R.T. test on an individual disk drive. The disk drive currently running a disk check should have a progress bar shown in the Progress column.

3-5. Security

3-5-1. User account

The User account window allows you to create more users, to change user password, and place limitations on users' privileges and administration rights. Up to 16 users can be created, including the default administrator.

1. By default, there are two user groups: Administrator and Normal user.
2. The normal users can not access the Settings window, meaning that normal users can not add or remove cameras, make changes to alarm, network, and all other system settings. When a normal user tries to access the system Settings window, the following message will prompt.

1. The administrator users can access all cameras recruited in the configuration; while the normal users can be configured to have access to some or all cameras.
2. The system blocks out the video feeds from users who are denied of the access to particular cameras. The alarms and the alarm-triggered recordings from those cameras will also be inaccessible for unauthorized users.

To create users,

1. From the Security > User account window, click on the Create... button.

1. Select a User group by unfolding its pull-down menu. Select either an Administrator or normal user as the user group.

1. Enter the User name and password. The max. number of characters for a user name is 64, with alphabetic and numeric characters including [0-9][a-z][A-Z][_]_[ ][-][.][,][@]. The max. number for password is also 64.
2. If you are creating a normal user with limited access to cameras, deselect the checkboxes in front of the cameras to deny the user access.
3. Click OK to close the configuration window. Repeat the process to create more users, and please remember to click the Save button to preserve your configuration after you created all users.

3-5-2. Access list

The access control applies to the access from a web client over HTTP and RTSP protocols. Three access configuration options are available:

1. Allow all: Allows access from all IP addresses.
2. Allow only: Allows access only from the listed IPs. You should manually enter the IPs for computers that need to access the NVR.

Note that you can use the asterisk (*) mark to represent all decimal numbers in each individual octet of the range of IP address: such as using 172.16.0.* for addresses ranging from 172.16.0.1 to 172.16.0.254.

A decimal number between two asterisks, e.g., <172.*.10.*>, is considered as invalid.

1. Deny only: Denies the access from the listed IPs. You should manually enter the IPs for computers that will be blocked out from the access. The configuration details is the same as those for the Allow only methodology.

3-6. Alarm

3-6-1. General

The events reported from individual cameras' digital inputs, digital outputs, and motion detection can be accommodated in the NVR system's alarm settings. The NVR also comes with DI and DO pins. These events will then be reported or commanding to trigger corresponding actions as follows:

1. Reporting events via Email or system buzzer.
2. Triggering video snapshot and text message by the occurrences of events to an FTP/HTTP site.
3. Triggering the camera(s) for its lens to move to a preset position.
4. Triggering the cameras' or the NVR's digital output.
5. Alerting the administrator with alarms indicators on the Alarm panel.
   You can create up to 16 instances of alarm.

Hardware connections to DIs or DOs, e.g., window sensors, should be made separately. The motion detection configuration is also made via a web console with individual cameras.

DO Email ▶snapshots
Motion detection Buzzer
		FTP ▶snapshots
		HTTP ▶messages
		Camera preset points
		Camera/NVR DO

To create an alarm,

1. Click on the Create... button.

1. The Create Alarm wizard window will prompt. You can manually enter a name for the current setting. You can enter up to 16 numeric or alphabetic characters for the name, including symbols such as [0-9][a-z][A-Z][_]. You can also designate the interval between one alarm and the next triggered alarm to avoid the situation that the alarms can be too frequently triggered.

The Activate alarm checkbox is selected by default. Click on the Next button to proceed.

1. On the Source window, select one or more cameras by selecting its checkboxes. The number of DI or DOs on each camera is automatically detected and displayed through individual checkboxes. The Motion detection function, if there are many detection windows configured on a camera, is all triggered by one checkbox.

Note that the triggering sources will be listed even if the camera is currently not connected.

1. On the Action window, you can select the Action type from a drop-down menu. The configuration details of each action type is discussion below.

4-1. Recording - When an event is triggered, the selected camera will record a video footage of the length defined by the pre-/post-event setting, to the NVR system. See below for an Alarm playback window.

Once an alarm is triggered, it is listed on the Alarm panel on the Liveview window. See page 45 for details about the functions of alarm panel and the alarm playback function.

4-2. Email - The Email action sends an Email to the administrator along with a snapshot of the event.

To configure Email notification, enter valid Email addresses as the Sender and Recipient addresses, an Email subject, and the SMTP server address through which the Email will be delivered. If you need to log in to SMTP server to deliver an Email, enter the User name and password for access to that account.

The Email subject and addresses can be composed of 254 characters in numeric or alphabetic characters including: [0-9][a-z][A-Z][_][[-][.][,][@]. You can enter the addresses of multiple recipients. Use semicolons, (;), to separate the addresses of multiple recipients.

Select the checkboxes below for which camera's snapshots will be sent along with the Email.

The file names of the snapshot jpeg files will look like this:

[MAC]_[DATE]_[TIME]_[CAMERA_INDEX].jpg

4-3. Buzzer - The buzzer is sounded on the occurrence of the event. The buzzer tones are categorized into: Major (1 long 2 shorts), Normal (3 shorts), and Minor (2 shorts) depending on the importance of an event. Select a Buzzer modulation from the dropdown list. A long tone has a duration of 1 second, while a short tone 0.5 second.

Select how many times the buzzer tones will be repeated on the occurrence of an event.

If events of different importance are issued at the same time, e.g., one major and one minor event, system will ignore the minor event and sound the buzzer tone for the major event only. The buzzer can be sounded either by the Alarm actions or the system events. If Alarm actions and system service events occur at the time, Alarm actions have the higher priority.

If multiple Alarm actions occur, the currently-sounded events can be depleted by the new event.

NOTE:

If system buzzer is sounded, turn it off in Settings > Logs > Error page. Click the Stop buzzer sound button.

Serious system faults, such as a missing volume, can trigger the system buzzer. Verify the cause of system fault and turn off the buzzer.

4-4. FTP - Snapshots from specified cameras can be uploaded to an FTP site on the occurrence of an event. Enter the FTP site address in the dotted-decimal notation, e.g., 159.22.151.20. Enter the login name and password for the user account. You can enter a directory name you prefer on the FTP site. The server port default is 21, a different number between 1025 and 65535 can also be assigned.

If authentication is not applied, login will proceed using the [anonymous] account.

The file names of the snapshot jpeg files will look like this:

[MAC]_[DATE]_[TIME]_[CAMERA_INDEX].jpg - If similar files already exist, an additional index number will be added to the end of file name.

4-5. HTTP - An event message is sent to an HTTP server on the occurrence of an event. The URL format for the HTTP server address is http://host{:port}[abs_path]. The applicable characters for the abs_path are: [0-9][a-z][A-Z][-].[.]:[/][?][&][@][_] [=].

If you need to log in to HTTP server, enter the User name and password for access to that account.

The user name can be composed of 64 numeric or alphabetic characters and symbols including [0-9][a-z][A-Z][_][[]-][.][.].

4-6. Camera preset points - A PTZ capable camera can move its lens to the preset position in case of a triggered alarm. For example, a triggered sensor may indicate an area of interest has been intruded, and a camera's field of view should be moved to cover that area. The precondition is that you properly set up preset positions on your PTZ cameras.

4-7. Camera DO - A triggered alarm triggers a camera's DO, e.g., an alarm siren.

4-8. NVR DO - A triggered alarm triggers the NVR's DO, e.g., an alarm siren.

1. On the Schedule page, you can select to activate or de-activate alarm triggers throughout a specific time. For example, in some situations you can disable the alarm triggers during the office hours, and choose to enable the triggers only during the off-office hours.

1. Click Finish to end the configuration. A configured instance will appear in lighter color and an asterisk mark in front to distinguish it as a changed entry that has not been applied.

Alarm - General

Save Create... Remove

* # Name Trigger interval Activate

= 1 Alarm1 3 Enable

2 Alarm2 3 Enable

= 3 Alarm3 3 Enable

1. Click Save to preserve and enable your alarm setting.
2. Repeat the process above to create more alarms according to the needs in your surveillance deployment.

3-6-2. Editing Alarms via Source, Action, and Schedule

1. Editing an existing instance -

1-1. To remove an existing alarm, select by a left-click, and then click on the Remove button.

1-2. To edit an existing alarm, select by a left-click, and then click on the Source, Action, or Schedule button on the left function tree. The associated parameters will display on different windows. You can then edit the previous configuration such as selecting a different triggering source, reactive action, or time span on a schedule.

While in the editing window, the Create and Remove buttons are not available.

3-6-3. Alarm - History

The History window provides access to search for past alarms.

You can designate your search citeria by the triggering devices, by the time of occurrence, or by the Event types such as Motion detection, DI, or DO. Note that the time search can only be dated back to 180 days ago.

The search results will be listed on the right with index number, time of occurrence, alarm name, and the Event type. The search results will display up to 200 entries. The outdated entries will be depleted.

3-7. Logs

By defaults, system logs will be written to every disk drives installed into the system. Up to 10,000 event logs will be kept with a segmented disk section within each drive. Old logs will be automatically removed if exceeding the 10,000 threshold.

The logs related functions include:

1. Export button: This button can be used to export the current event logs in the CSV format. The default export file name is [MAC]_[DATE]_[TIME].csv. For example, an exported file may look like this: 0002D1112233_20130222_011013.csv.
2. Page selector buttons: (from left to right) First page, Previous page, Next page, and the Last page.
3. Page size: 20 50 100 200 Page size buttons: These buttons determine how many event logs will be displayed on a single page. The selected number will be displayed without the underline.

The event logs fall into the following categories: System, Recording, User, and Error. A click on each category brings out a list of event logs belonging to that category.

Logs	22	2/19/2013 3:27:44 PM	11
System	21	2/19/2013 3:27:44 PM	9
Recording	20	2/19/2013 3:27:44 PM	14

	16	2/19/2013 3:27:40 PM	6
	15	2/19/2013 3:27:40 PM	7

Usually the Error events can trigger the onboard buzzer. Use the Stop buzzer sound button to mute the buzzer. The will buzzer will still be sounded if the system is powered off and then powered on until the errors can be corrected, such as a missing volume.

The following information is shown with each event log:

1. Level: The following severity level can be applied to an event.

1-1. Error: Configuration errors such as lack of system memory or a faulty camera password.
1-2. Info: General information such as acquiring an IP from DHCP server.
1-3. Warning: Configuration and operation errors such as re-starting server service.
1-4. Config: Events that are generated due to configuration changes, such as a change in address or that to a camera configuration.

Chapter Four Operation

IMPORTANT:

1. Before operating the NVR, make sure you have properly installed hard drives and configured the storage volumes. Otherwise, you will not be able to operate most of the system's functionality.
2. Since the NVR system comes with 32-bit plug-ins for screen control, if your PC runs a default 64-bit IE browser and you manually enter the NVR's address on the browser, your browser session may malfunction. Instead, if you double-click on the discovered NVR on the IW2 utility, a 32-bit IE browser will open.

4-1. Liveview

4-1-1. Placing Cameras into the Layout

Legends and definitions of icons on the layout panel have been described on page 32.

It is presumed that you have properly inserted all network cameras in your deployment as previously described on page 73. All 16 cameras should be listed on the Camera list.

Note that layout design can only be performed by the system administrator.

To begin the design of your layout,

1. Select a layout pattern by a single click. The options are: 1x1, 1+3, 1+5, 2x2, and 4x4.

1. Click and drag cameras from the Camera list to empty cells on your layout. Repeat the action until you placed all your cameras into the layout. You may also double-click on a camera's thumbnail to fill it into the first unoccupied view cell.

2
Camera list

1. When you filled up the current layout, e.g., 6 camera into the 1+5 layout, click the page switch button to continue on the next layout page.

2. When you are done with the current layout design, i.e., the user layout 1, click Save to preserve your settings. This message prompts on the screen whenever any change is made to the current layout.

1. You can create more user layouts by mouse-overing the user layout button. You may create more user layouts for different purposes, such as for the use of different users, or playing different views of a fisheye camera on multiple view cells.

The fisheye mode button is available on the view cell where you inserted a fisheye camera. When a regional view is displayed, the shooting angle and image orientation is kept with the layout. See page 41 to see more about fisheye viewing modes.

Placing different regional views of a fisheye camera into view cells will look like this:

NOTE:

Only an administrator can alter the display modes of fisheye cameras. Although ordinary users can make changes to a regional view, his changes will not be preserved after a console is re-started.

In addition to fisheye cameras, if a camera has a wide field of view, you may also display its different fields of view in multiple view cells. Some view cell may also contain a PiP view that is digitally zoomed.

If users were created and some cameras are excluded from their access, a user may log in and see the locked-on cells as shown below:

A user who has limited access rights may still re-arrange the layout of view cells. However, his configuration change will not be saved after he leaves the current console.

NOTE:

By default, every users or administrator logs in to the Live view window to the last layout page he visited. The last layout page a user visited during the previous console becomes the default layout.

4-1-2. PTZ and Other Screen Controls

Note that the PTZ control panel only applies when you select a view cell with a camera that comes with mechanical PTZ functions. Currently the e-PTZ function is not supported by the NVR system.

With a PTZ camera, the buttons on the PTZ panel become functional when you mouse over its GUI elements. For all compatible cameras and exerting Zoom, Focus, and Patrol functions, please refer to page 43 for details. The Zoom function, for example, requires a camera that comes with a motorized zoom module, and may not be applicable to every PTZ camera.

The preset positions and the patrol functions require the associated configuration on the cameras via a web console. Before you make use of these functions, you should set up the preset positions on a web console with the camera. The NVR GUI does not provide the configuration options with PTZ preset positions.

You can use Preset button to display preset positions and tell the camera to move and point at the preset direction, and to perform a camera tour to visit these positions in a consecutive order.

To access live view control,

1. Click on a view cell. The view cell will become a focused view cell. The streaming control buttons will be listed at the bottom of a view cell. These buttons have been discussed on page 37.
2. The 2nd click on a view cell enlarges it to the full of the live view area. The 3rd click reduces its size to the original focused view.
3. To deselect a view cell, you can click on another view cell in the display area or click on the Restore button.

A selected, focused, view cell.

NOTE:

If you have concerns with the display quality and frame rate per second, refer to page 79 for how to configure video feeds for live viewing as well as for video recording. The configuration options can be found in Settings > Camera > Video.

Note that the constant bit rate methodology is applied in this system and it sets an upper threshold on the size of IP packets sent with the video streams. Image quality will be slightly compromised if reaching the ceiling of allowable bandwidth.

To place bookmarks and exert screen controls,

On a focused view cell, you can temporarily stop or start an ongoing streaming, or place a bookmark that saves a short description and a one-minute footage from the current feed. The bookmark is also displayed along with the recorded video, and therefore it is easier to look for a specific moment in time when you need to trace back for a scenario later.

The bookmark function can be executed on a live or recorded stream when you observe a situation from your Live view or Playback window. The precondition of using this function is that the video stream, while you are watching it on the view cell, must be recorded to the NVR at the same time.

To add a bookmark,

1. Click on the button,
2. Enter a short description that can be as long as 120 characters.
3. Click on the + button or simply press Enter on your keyboard.

To Activate and Deactivate PiP function,

PiP is short for Picture in Picture, a function that provides digital zoom into a live video. When activated, a Global view window will appear at the lower right of the view cell as shown below. You can display only a portion of the complete video frame as an area of your interest. Using a click and drag on the ROI window, you can instantly move to other areas within the video frame.

You can resize the ROI window by a mouse hover on the lower-right corner of the window until the resize mark appears. The default size of the ROI window is 25% of the Global view.

Click on the deactivate button to close the PiP window.

Note that not every camera supports the PiP function. For example, PTZ cameras and fisheye cameras do not support the PiP feature.

Refer to page 37 for GUI legends and individual functionality.

4-1-3. Audio

Audio is only transmitted through the camera in a view cell that is currently selected. You can manually tune the volume level, mute, or unmute the audio feed through a view cell.

4-1-4. Camera Properties and Controls

You can click on the underlined name entry of a camera on the camera list to open its properties window. Here you can find a short description of the camera name, address, and model name. You can also enable or disable the scheduled or continuous recording set for the camera. Click on their associated icons, √, 🔍 to change their recording status.

For a camera that is not performing a continuous recording, you can click on the Manual Recording button, √, to start a manual recording. The recording will stop using the same button.

You can also manually turn on the digital output 🔒, e.g., to trigger an external alarm that is connected to a specific camera.

4-1-5. Alarm Panel

To receive alarms from cameras, you need to configure alarm triggers in the Settings > Alarm configuration window (see page 99). Network cameras' digital inputs, digital outputs, or motion detection can all be used to detect conditions in external environments. You can configure certain kind of actions to take place in response to the alarms: such as

1. recording the immediate image,
2. sends an Email notification,
3. sounds the onboard buzzer,
   4, sends snapshots to an FTP server,
4. sends videos to web server,
5. moves camera lens to a preset location,
6. triggers a camera's digital output.

The operation details of the Alarm panel and Alarm Playback utility have been described on page 45.

4-1-6. Layout view Control Buttons

1. When editing a user layout, you can use this button to clear all view cells of inserted cameras.
2. 📋 is button extends the current layout to the full of the screen.
3. The Rotate function lets system display successive pages in a user layout by the

intervals of 10 seconds. The layout page that does not contain camera views will be skipped.

A Rotate action will stop when you

1. move to another page in the user layout,
2. move to another user layout,
3. click to select a view cell,
4. remove a camera from view cell,
5. click to disable the rotation function.

When your current layout spans across multiple pages, use the arrow buttons to switch from one page to another. The index number of the current page will be shown between the arrow buttons.

1. The DI/DO panel displays the current digital input conditions and the manual trigger DO button. When a DO is triggered, it is indicated by a white circle. Click on the circular button in front of DO to trigger a DO signal.

A DO signal can also be associated with the Alarm setting for the NVR to take related actions, such as the Alarm recording.

Note that once triggered, the DO signal will be continuous and the DO-triggered events will prompt continuously. Click on the DO button again until the white circle disappears.

4-2. Playback

The elements in the Camera list on a Playback window are similar to those on a Liveview window. Please refer to page 30 for details on the Camera list panel.

However, on a Playback window, you can not:

1. Users can not click and drag a camera thumbnail to a playback view cell.
2. A double-click on a camera does not display video in a view cell. A double-click displays a calendar where days with recorded videos are shown.

4-2-1. Begin Playback and Search for Past Recordings

1. Select a layout. You can display the playback views of multiple cameras on one screen.
2. Select a view cell on the Playback window,
3. Double-click on a camera.
4. The Calendar panel will display the days video recording actually took place. And those days will be highlighted by a blue background (as the 25th and 28th in the screen below.)

NOTE:

If a video stream is recorded in the MJPEG format, it will not be playable on the Playback window.

4-2-2. Past Alarms and Bookmarks

When you selected a day when alarms took place on a camera, the alarms will be listed on the Alarm panel. Up to 200 entries can be listed on a single page, and a max. of 1,000 entries across multiple pages.

You may then,

1. Mouse over the alarm thumbnails and click on the play button. The Playback window will then play back the video recorded by the time of the occurrence.
2. Unlike the Alarm playback function on the Liveview window, which only plays back the related video for only one minute, the alarm playback will continue throughout the recording of that day.

If you set up multiple triggering sources on a camera, you can use the Alarm filter button to find the alarms of a specific type.

You can select the check circles to narrow down the types of listed alarms using search citeria by Alarm name, Motion, DI, DO, or Bookmark.

Note that if searching by the Alarm name, the search does not apply to the camera model name that is automatically appended to the description of an alarm. Only the name of an alarm should apply in the search.

Note that the bookmarks you inserted on the Liveview window will be listed on the Alarm panel, and the bookmarks will also appear on the slide bar of the Playback window.

To retrieve or view the video clip tagged by the bookmark, click on it to play the video that was recorded by the time bookmark was inserted.

4-2-3. Synchronous Playback

The NVR supports synchronous playback, which allows you to review video clips from up to 4 cameras at the same time. These video clips will be retrieved simultaneously all playing for a specific point in time.

To perform synchronous playback:

1. Select a layout from the Layout panel, e.g., a 2x2 layout.
2. Click on the Synchronous playback button.
3. Double-click to select a camera from the camera list. This camera becomes the Master camera.
4. When the Calendar panel appears, click to select a date your prefer.
5. Click and drag other cameras from the camera list to the empty view cells. These cameras will play back videos according to your operation on the Master camera.

Note the following when using the Synchronous playback:

1. Only the alarms triggered on the Master camera will be shown. In the Synchronous mode, you can not find the alarms or bookmarks generated for other cameras.
2. The playback speed, selection of video clips, and alarm playback of all cameras are made synchronous.

4-2-4. Export media

To export video clips,

1. Click on the Export media button on the tool bar, while the Playback window is playing a video section of your interest.

2. An Export media window will prompt.

1. Select the file format using the pull-down menu. An EXE file is an self-executable file playable by an embedded Media Player, and is playable on systems running different OSes than the Windows. The 3GP format is a multimedia container format for 3G UMTS services. These files can be played on Quicktime, Realplayer, and VLC. The file name will look like this: [MAC]_ [DATE]_ [TIME]_ [CAMERA_INDEX].[3gp/exe].
2. Select an export length of video by 1, 3, 5, or 10 minutes. The actual length can be longer due to the fact that the program needs to trace back to the previous I-frame for a complete rendering of video frames into the media.
3. Click OK to proceed.
4. System will prompt you for the EXE file. Click Save to proceed.

1. Select a location to store your file.

1. When the progress is done, click Close.

1. A self-executable EXE file should look like this.

If users select to export videos made of two different codecs (e.g., MPEG-4 and H.264), the following message will display:

Stop converting media due to streaming data has been changed.

Users should then find out the beginning of the time when video codec was changed in order to export another part of the footage.

4-2-5. Time Search

Use the time line slide bar to find the nearest recording from a specific point in time.

Details of the control bar in the Playback window can be found on page 53.

If the need arises to more accurately pin-point the occurrence of an event, you can use the Timeline zoomer and the slider thumb on the time line for a closer view into the existing recording.

		Timeline zoomer. Use the zoomer to zoom in for more precise skimming.
	Timeline slider thumb. Click and drag this thumb button to move along and reach a specific point in time.

You can use the timeline zoomer to scale down the span of time. For example, if the time span is reduced to 1 hour, then each section on the time line represents 15 minutes of recording. The total time span on a timeline starts from the minimal of 4 minutes, 20 minutes, 40 minutes, 1 hour, and up to a maximum of 24 hours.

In the Synchronous play mode, a change to the zoomer will be reflected by all synchronously playing view cells.

If recordings take place by an event-triggered recording, the intervals between recordings can be down to 1 minute, and the individual recordings will not be easily discernible. In this situation, you can mouse over the timeline to pin-point individual recording instances.

4-3. Other Functions - Using the Backup Button

The Backup function supports USB devices formatted in FAT32 or all other FAT file format.

The Backup function saves a replica of your system configuration profile to a USB drive. Once the USB is inserted, you should be able to hear two beeps, indicating the NVR has recognized the presence of the USB drive. You can then press the Backup button. The status LED will flash orange for 2 seconds, and the configuration backup is written to the USB drive.

You should then remove the USB drive.

To restore from a previous backed-up file, insert the USB drive with a previously-saved profile. Press the Backup button for 4 to 5 seconds, and then wait for the system to reset itself. The process should take 3 or 4 minutes.

You can also restore from a previous backed-up file, in the System > Backup menu. Use the Browse button to locate the backup file. Click the Restore button.

A warning message will prompt. The current recording operation will be temporarily interrupted when restarting service. The process should take 3 or 4 minutes. After a reset, you system configuration will be restored to the previous state.
