Frequently Asked Questions - NVR304-16EP-B UniView

How do I reset the admin password if I forgot it?

On the login dialog, double-click the lower left corner as admin. A dialog appears with the serial number. Contact your dealer for a temporary password. You can also use the mobile app to scan the QR code on the NVR (Settings > Forgot Device Password).

Why can't I open the web login page using the default IP 192.168.1.30?

Try using 192.168.0.30 instead. Also ensure your PC is on the same subnet and the NVR is properly connected to the network.

The web plugin (ActiveX) fails to load. What should I do?

Close the browser during installation, disable firewall and antivirus, enable IE to check for newer versions of stored pages (Tools > Internet Options > General > Settings), add the NVR IP to trusted sites and Compatibility View list, and clear IE cache.

No video displayed in live view on the web interface.

Check if the bit rate is 0 Mbps. If yes, disable firewall and antivirus on your PC. If not, the graphics card driver may be faulty. Reinstall the driver.

A camera shows 'Offline' or 'No Link'. What can I do?

Go to Maintain > System Info > Camera to see the offline cause. Common issues: network disconnection, incorrect username/password, weak password, or insufficient bandwidth. Check the camera password set in the NVR matches the camera's web interface password. If weak password, set a strong one on the camera's web page.

Some cameras display 'No Resource' during live view.

Set the camera to encode the sub stream and decrease its resolution to D1. Enable 'Sub Stream First' under Preview > Advanced to use sub streams for live view.

Live view works but no recordings are found.

Verify that a recording schedule is correctly configured (Storage > Recording). Check that the NVR time and time zone are correct. Ensure the hard disk storing recordings is not damaged or overwritten.

Motion detection does not work.

Ensure motion detection is enabled under Alarm > Motion, the detection area is correctly drawn, sensitivity is appropriate, and the arming schedule is set. Also confirm that recording/snapshot actions are triggered.

A hard disk is not recognized by the NVR.

Use the power adapter supplied with the NVR. Power down and remount the disk, or try another disk slot. Check disk compatibility; contact your dealer for a list of supported models.

How do I upgrade the NVR firmware?

Go to Maintain > Upgrade. You can upgrade locally via a USB drive containing the firmware file, or by cloud (ensure NVR has internet and DNS configured). Do not power off during upgrade.

Preface

This manual describes how to use your NVR locally or on the Web interface.

In this manual, the terms IP camera and IPC refer to the same thing: network camera, which requires a connection to the network. And the IP device mentioned in this manual refers to an IP camera (also known as network camera) or a Digital Video Server (DVS).

Part I Local Operations

An NVR supports two types of operations: local operations and web-based remote operations. With local operations you connect a monitor and a mouse to the NVR and use the mouse to operate. If your NVR has buttons on the front panel or is delivered with a remote control, you may also control your NVR by pressing the front panel buttons or using the remote control.

The NVR has an embedded web server and allows web-based operations. To do this, you need a PC that has a network connection to the NVR and is installed with a web browser. You just need to navigate to the NVR's IP address and log in to the Web interface like you log in to the system locally.

This section describes local operations.

3. Click Apply to save the settings.

NOTE!

• For an NVR with multiple NICs, you can configure the NICs and choose a default route (currently NIC1).
• If your NVR has a PoE port or a switching port, you can configure an internal NIC IPv4 address.

CAUTION!

• If you switch the working mode, the enabled 802.1x and ARP protection will be disabled automatically.
• The valid MTU ranges from 576 to 1500 (1280-1500 for IPv6). To use IPv6, make sure the NVR and PC can connect to each other using IPv6 addresses. To view live or recorded videos, make sur the IPv4 addresses are also connectable.

DDNS

If your NVR is connected to the Internet through PPPoE, the IP address of the network changes every time it connects to the ISP server without your awareness. This is inconvenient when you remotely access your NVR with an IP address. To avoid this issue, you can register with an DDNS server to obtain a domain name for your NVR and then access your NVR by visiting the domain name instead of an IP address (http://DDNS server address/NVR's domain name) using a web browser.

1. Click System > Network > DDNS.

2. Enable DDNS, select a DDNS type, and then complete other settings.

- If the DDNS type is DynDNS or No-IP, enter the domain name, username and password. The domain name is the one that you have successfully registered at a domain name registration website (e.g., DynDNS). The username and password are those of the account you have registered at the domain name registration website (e.g., DynDNS).

	: 0(main stream) or 1(sub stream)

NOTE!

• A valid port number ranges from 1 to 65535, among which 21, 23, 2000, 3702 and 60000 are reserved.
• An RTSP URL can be used to view live video of a channel of the current NVR from another NVR. See Option 4 in Adding an IP Device for more information.

3. Click Apply to save the settings.

Port Mapping

Two port mapping methods are available:

• Universal Plug and Play (UPnP)
- Internal and external mapping

UPnP

UPnP enables the NVR to discover other devices on the network and establish network services such as data sharing and communication.

To use UPnP in your NVR, you must enable UPnP in the connected router. With UPnP enabled for Network Address Translation (NAT), the ports on the NVR can be mapped automatically to the router, and computers can access your NVR from outside the LAN.

1. Click System > Network > Port Mapping.
2. UPnP is enabled by default. Select the desired mapping type from the drop-down list. To map ports manually, select Manual and then set external ports for the router.

NOTE!

• Automatic mapping (Auto) is recommended. Ports will conflict if not configured properly.
• For an NVR with multiple NICs, port mapping should be configured based on the NIC specified as the default route.

Enable Port Mapping
Mapping Mode	UPnP Manual
UPnP Mapping	Auto
HTTP Port	50554
RTSP Port	50818
HTTPS Port	57703
Port Type External IP Address External Port Internal Port UPnP Status
HTTP Port 0.0.0.0 50554 80 Active
RTSP Port N/A 50818 554 Inactive
HTTPS Port N/A 57703 443 Inactive

1. Click Refresh and check that Active is displayed for these ports under UPnP Status.
2. Click Apply to save the settings.

Manual Port Mapping

If your router does not support UPnP, then you need to configure internal and external ports manually.

NOTE!

• The principle of port mapping is that the internal and external ports of the NVR are consistent with that of the router.

• Some routers may require the same internal and external ports for the NVR and the router.

• Click System > Network > Port Mapping.

• Select Manual for Mapping Mode, and then set external ports manually.

Enable Port Mapping	☑
Mapping Mode	○UPnP	●Manual
HTTP Port	80
RTSP Port	554
HTTPS Port	443

3. Click Apply to save the settings.

NOTE!

After port mapping is completed, you may access the Web client of your NVR by entering the following information in the address bar of your web browser: router's WAN port IP address:external HTTP port. For example, if 10.2.2.10 is the IP address and 82 is the HTTP port, then you enter http://10.2.2.10:82.

Email

After Email is enabled as a triggered action (in Trigger Actions windows) and configured properly, the NVR sends an email notification to specified email address(es) if an alarm occurs within the time period(s) set in the arming schedule. The email contains basic alarm information such as alarm type, alarm time, camera ID, and camera name, etc.

Before using this function, make sure the NVR has a functional connection to an SMTP server with which you have a valid email account. Depending on the intended recipients, a connection to the Internet may be required.

Only certain NVR models support this function.

RAID	HDD Qty
RAID 0	2-8
RAID 1	2
RAID 5	3-8
RAID 6	4-8
RAID 10	4-16 (Must be an integral multiple of 2, e.g., 4, 8, 10, etc).
RAID 50	6-16
RAID 60	8-16

Enabling RAID

You need to enable RAID first.

1. Click Storage > Array.
2. Select the check box to enable RAID. A confirmation message appears. Click Yes.

Creating an Array

It is recommended to configure a hot spare disk to ensure reliable system operation and successful rebuilding in case an array fails.

1. Click Storage > Array.
2. To create an array automatically, click One-click Create.

NOTE!

• There is no need to select disks when creating an array with One-click Create. The system identifies all usable disks. RAID 1 is created when two disks are available. When three or more disks are available, RAID 5 is created. If more than four disks are available, a global hot spare disk will be created.

• Arrays created in this way are named ARRAYX, for example, ARRAY1, ARRAY2.

• To create an array manually, select the desired disks and then click Create. In the window displayed, enter the array name, select the array type, and select local disks. Click OK to complete the setup. Note that no hot spare disk will be created automatically. Make sure all disks are selected to create array(s); otherwise, disk space will be wasted (because disks that are not selected will not be used for storage).

Rebuilding an Array

By checking array status you can determine whether maintenance is necessary. An array is in one of four statuses: normal, degraded, damaged, rebuild. The status is normal if no physical disk is lost. When the number of physical disks lost reaches the specified value, the array is considered damaged. The status between normal and damaged is degraded. A degraded array can be recovered to normal status through rebuilding.

NOTE!

Take RAID 5 that consists of 4 disks as an example. The array is degraded when one disk is lost. When two disks are lost, the array is damaged.

A degraded array can be automatically rebuilt in ten minutes if these conditions are met: a hot spare disk is available; the capacity of the hot spare disk is not less than that of any disk in the array. A degraded array without a hot spare disk can only be rebuilt manually under Storage > Array > Array. By default the first local disk that satisfies requirements is selected.

Deleting an Array

CAUTION!

Deleting an array will erase all data on it.

1. Click Storage > Array > Array.
2. Click 📄 for the array to delete. A confirmation message appears. Click Yes.
