3 Video Streaming

In this section, we will show you ways to set up and start your video streams.

3.1 Streaming Network Connection and Device Search

Let's first detail how to connect the NVS-33 to a network with or without a DHCP server, and describes how to acquire the NVS-33's IP address.

Connecting to a DHCP Network (DHCP Mode)

Follow the procedure below to scan your DHCP network for connected NVS-33 devices.

Note: The NVS-33 will be automatically assigned an IP address upon connection to the DHCP network.

1. Connect the NVS-33's LAN port to the network via an Ethernet cable.

2. Turn on the NVS-33's power, and the NVS-33 will also be turned ON in the DHCP mode by default.

1. Connect the laptop to the same network that the NVS-33 is connected to and download the free IP Finder utility program from the product page https://www.datavideo.com/tw/product/NVS-33.

2. Double click the IP Finder utility program icon to open the IP Finder interface.

3. Click the SCAN button to start searching for connected devices.

Connecting to a NON-DHCP Network (Static IP)

Upon connection to a non-DHCP network, the NVS-33 will not be assigned of any IP addresses. As such it is recommended that you manually assign a fixed IP address to the device or use the default IP address (192.168.1.60).

Default Fixed IP

Default Fixed IP is primarily used in point-to-point connection, such as connecting the PC to the NVS-33 directly. In a non-DHCP environment, the NVS-33 works in fixed IP mode only. To configure the NVS-33 to the default IP, please follow the steps outlined below:

1. Connect the NVS-33's LAN port to the network via an Ethernet cable.

2. Turn on the NVS-33's power and the NVS-33 will also be turned ON in the DHCP mode by default.

3. Search for the NVS-33 device according to the method as detailed in the previous DHCP section. Once found, log into the user interface on the web browser.

4. Enter the system page by clicking the "System" tab on the home of the user interface.

5. In the "Network Setting", disable the DHCP mode.

6. You will then be allowed to manually enter the static IP address once the DHCP mode is disabled. The static IP is 192.168.1.60 by default. The subnet mask and default gateway are 255.255.255.0 and 192.168.1.254 respectively.

Tip: If you forget or lose the IP address, do the following to reset the network settings.

- Please restart the power of the NVS-33 and all buttons will be shown in solid white at this time.

- Please wait for about 30 seconds. After that, all buttons will be shown in red and then go back to solid white.

- Please press the RECORD and STREAM buttons at the same time.

- When buttons are shown in blinking red for about 5 seconds, please release the pressed buttons. At this time, all buttons will go back to solid white.

- Please reboot your PC.

• The IP address should be the default IP which is 192.168.1.60.

Troubleshooting the Network Connection

Connect the NVS-33 to the network and open the IP Finder utility program. Scan for the device. If not found, it is possible that your network is not assigning IP addresses. Reasons of this are outlined as follows:

• Router or DHCP server is not connected to the network.
• New devices are blocked by the network administrator.
• Anti-virus software or the firewall blocks the communication.

Solve the problem by attempting the following:

• Turn off the router, wait for 10 seconds then turn on the router again.

• Reset the NVS-33 to the factory default:

• Please restart the power of the NVS-33 and all buttons will be shown in solid white at this time

• Please wait for about 30 seconds. After that, all buttons will be shown in red and then go back to solid white.
• Please press the RECORD and STREAM buttons at the same time.
• When buttons are shown in blinking red for about 5 seconds, please release the pressed buttons. At this time, all buttons will go back to solid white.
• Please reboot your PC.

If the problem still persists, try the following ways:

• Temporarily shut down the anti-virus software or firewall.
• Make sure no other devices are connected to the LAN (wired or wireless) because this may result in IP conflicts.

After trying all methods and if the problem is still not solved, the NVS-33 video streaming server offers the fixed IP feature that allows you to establish direct connection to the NVS-33. The default IP address is 192.168.1.60.

This method allows you to configure the NVS device to the IP range of your network so that you do not need a DHCP server to gain access to the NVS device.

- Connect your PC to the NVS device directly using an Ethernet cable (not necessarily a crossover cable).

Next, change the network settings of your Windows7 or Windows 10 PC or laptop.

• Click START located at the bottom left corner of your screen.
• On the text bar, enter Network Connections then click the icon that appears.
• Double click the network adapter that connects your PC or laptop to the network.

- Click the "Properties" button.

- Select "Internet Protocol Version 4 (TCP/IPv4)" option and click the "Properties" button.

- Check the "Obtain an IP address automatically" option.

- Enter IPv4 settings:

- IP Address: 192.168.1.2

- Subnet Mask: 255.255.255.0 (System default is 255.255.255.0)

- Default Gateway: Not required for one-to-one connection.

- Subnet Mask: 255.255.255.0 (System default is 255.255.255.0) - Default Gateway: Not required for one-to-one connection.

Note: Please write down the IPv4 address previously entered as it may be needed after you are done with streaming or recording.

- The NVS-33 should now be connected with an IP address of 192.168.1.60. If the NVS-33 still cannot connect, simply restore the NVS-33 to the factory defaults.

• Please restart the power of the NVS-33 and all buttons will be shown in solid white at this time.
• Please wait for about 30 seconds. After that, all buttons will be shown in red and then go back to solid white.

• Please press the RECORD and STREAM buttons at the same time.

• When buttons are shown in blinking red for about 5 seconds, please release the pressed buttons. At this time, all buttons will go back to solid white.

• Please reboot your PC.
• Make sure no other devices are connected to the LAN (wired or wireless) because this may result in IP conflicts.

- Login the NVS-33 via a web browser.

• Default user name is admin
• Default password is 000000

- Click the "System" tab then on the system page, enter network settings such as static IP and default gateway. Make sure that the default gateway matches your connected network and no device shares the same IP as the NVS-33.

For example, if your router's default gateway IP is 10.10.1.1, then in the default gateway field, you should also enter 10.10.1.1. Then set the IP address of the NVS-33 to 10.10.1.X, which can range from 10.10.1.2 to 10.10.1.255. Pick an unused IP address.

Network Setting
DHCP	Static IP
Enable(DNS AUTO)	192.168.1.60
Subnet Mask	Default Gateway
255.255.255.0	192.168.1.254
Primary DNS	Secondary DNS(Alternative)
MAC ADDRESS
00:07:36:03:C0:20

• DHCP: Disable
• Static IP: X.X.X.Y; the first three decimal numbers must be the same as your router or switch. The number Y must be a number not used by any devices connected to the network.
• Subnet Mask: 255.255.255.0
• Default Gateway: Z.Z.Z.Z; same as the gateway IP of your router or switch.

Note: Some router may require special gateway IP setting; instead of the standard 192.168.1.1. Therefore, you should check the network properties on the PC before switching to the fixed IP mode.

For example, some routers have a gateway IP of 192.168.1.254 and as a result, the default gateway and primary DNS fields on the NVS-33 must also be configured to 192.168.1.254.

• Primary DNS: Same as the default gateway IP, which, if causing issues, can be changed to 8.8.8.8 or 8.8.4.4 (Public DNS provided by Google).
• Click the "Submit" button to save the network settings.
• Reconnect the PC and the NVS-33 to the network.
• Restore the PC's original network settings.
• Shut down the NVS-33; wait for approximately five seconds before turning the NVS-33 back ON.
• You should be able to access the NVS-33 through the fixed IP address.

Advanced Troubleshooting

If you still are unable to connect, please try the following:

• Use the ARP table to search for the encoder's MAC address; the device's MAC address is on the print label at the bottom of your NVS-33.
  • MAC address starts with 00:07:36:03:xx:xx.
• On the command prompt (terminal on MAC OS), enter "arp -a" then press enter key to display an ARP list. See if the NVS-33 is successfully connected to the network.
• Execute services.msc, and on the right column of the "Services" window, locate "DHCP Client" then click "Restart".
• On the command prompt, enter ipconfig/flushdns followed by ipconfig/release and ipconfig/renew.

3.2 Web User Interface

By now, we have obtained the IP addresses of the PC and the NVS-33. Enter the NVS-33's IP address into the address bar of a browser then hit the ENTER button. Login by entering the user name as well as the password into a pop-up dialogue box as shown below.

Stream and Record Settings

In the section, you will be introduced various setting options of stream and record functions.

Common Setting Items for Streaming and Recording
	Video SourceSelect SDI or HDMI as the video input source from this drop-down menu.
Audio Source	Audio SourceThis drop-down menu allows users to select the audio source of your video stream. The options are embedded audio (Digital Audio), external audio (RCA Analog Audio) and mixed audio (Audio Mixer).
Bitrate ModeMidHighMidLow	Bitrate ModeThe bitrate mode sets the video bitrate mode for your video stream. The available modes are high, mid and low.Note: You can also switch between different bitrate modes by pressing the Bitrate button on the front panel. SeeSection 2.1for details.
Stream Encoder Settings
ResolutionSame as InputSame as Input1920 × 10801280 × 720960 × 540720 × 576720 × 480640 × 480320 × 240160 × 128	ResolutionThe first step of encoder setup is to adjust the image size. It is best to either match your original video source or scale it down. For example, capture at HD 720 and stream at HD 720. Or capture at HD 720 and stream at 540 (high).You should never be scaling up and streaming at a higher resolution than your original video source. For example, it does not make sense to capture at 720 and stream at 1080. Note that you will also have no gain in quality and you are using more bandwidth than is necessary for your viewers.You should also be aware that higher resolutions require greater processing power to encode the stream. Attempting too high of a resolution on too little processing power can result in degraded image quality and corrupted or interrupted streams or recordings.Frame RateSelect a frame rate from the drop-down menu for video streaming. Note that frame rates should always match the frame rate of the video source.
	Auto StreamIf the Auto Stream is enabled, in the event of power outage, the stream will be automatically restored after the switcher is powered ON again.
	ProfileProfile sets the H.264 encoding profile for your stream. The available options are Baseline, Main, and High. Typically, High profile provides the best image quality and is suitable in most instances. However, depending on the decoder used when viewing the stream, such as with mobiles devices, a Main or Baseline profile may be required.
Video Bitrate (bps)1.5 M8 M7 M6 M5 M4 M3 M2.5 M2 M1.5 M1 M512 K256 K	Video Bitrate (bps)The bitrate of the video specifies the amount of information stored in the video. The higher the bitrate is, the clearer the video is. However, when choosing your encoding settings for streaming, you should first check your available upload bandwidth. A good rule of thumb is for the bitrate of your stream to use no more than 50% of your available upload bandwidth capacity on aDEDICATEDline. For example, if the result you get from a speed test shows that you have 2Mbps of upload speed available, your combined audio and video bitrate should not exceed 1Mbps.Usually high bitrate means good image quality; however, there are also exceptions. For example, SD video may appear acceptable at 1000 Kbps (1M) but HD video is unacceptable at 1000 Kbps. Therefore we recommend the following settings for your video bitrate:When NVS-33 is in record-only mode, the recommended video bitrate is 15 Mbps.When NVS-33 is in stream-only mode, the recommended video bitrate is 10 Mbps.When NVS-33 streams and records simultaneously, sum of the stream and record video bitrates should not exceed 12Mbps.
	Audio Bitrate (bps)The NVS-33 offers the user the following audio bitrates at which you may want to stream the audio. It is recommended to select 128Kbps or higher.
GOP60180160140120100605030252015105321	GOPGOP pattern with longer GOP length encodes video very efficiently. Shorter GOP lengths usually work better with video that has quick movements, but they do not compress the data rate as much. Depending on your applications, the NVS-33 offers the user 16 GOP sizes ranging from 1 to 180.
Stream Settings
Stream TypeRTSPRTSPRTMPTSHLSSRT	Stream TypeThe NVS-33 offers the user five stream types. There are RTSP, RTMP, TS, HLS and SRT.Please note that when streaming, the NVS-33 converts video into data, which are sent across an IP network. High bitrates consume more bandwidth across the IP network. In a gigabit office LAN, high bitrate may not be a concern and Speed/Bandwidth is therefore not the limitation in a NVS-33 application environment.If your available bandwidth is limited, you should reduce both your resolution and your bitrate accordingly. A good rule of thumb is for the bitrate of your stream to use no more than 50% of your available upload bandwidth capacity on a dedicated line. For example, if the result you get from a speed test shows that you have 2Mbps of upload speed
	available, your combined audio and video bitrate should not exceed 1Mbps.

Higher resolutions use more pixels to create an image. This means that greater amounts of detail can be expressed in the image, but larger files sizes and a greater amount of storage (i.e. hard drive space) are required to save the images or video.
FramerateSame as InputSame as Input60.0050.0030.0025.0020.0015.0010.005.001.00		Frame RateFrame rate greatly impacts the style and viewing experience of a video. Different frame rates yield different viewing experiences, and choosing a frame rate often means choosing between things such as how realistic you want your video to look, or whether or not you plan to use techniques such as slow motion or motion blur effects.Below is a list of common options for different applications:24fps – This is the standard for movies and TV shows, and it was determined to be the minimum speed needed to capture video while still maintaining realistic motion.30fps – Videos with a lot of motion, such as sports, will often benefit from the extra frames per second.60+fps – Anything higher than 30fps is mainly used to create slow motion video or to record video game footage.
