Video Streaming and Recording 

The KMU-200 4K Multi-Channel Touch Screen Region of Interest includes a built-in Video 
Streaming Server (NVS-31 MARK II) allowing the user to stream and record your program at 
the same time. From any SDI/HDMI input sources, the Datavideo’s video streaming server 
generates an H.264 encoded stream that is compliant with RTSP or RTMP protocols. While 
encoding the video at bit rates appropriate for live streaming, the Datavideo NVS-31 MARK 
II concurrently records a high-quality MP4 file to an SD card. 

Note: The built-in video streaming server and recording device are referred to as NVS-31 
MARK II.

 

5.1  Streaming Network Connection and Device Search 

This section details how to connect the NVS-31 MARK II to a network with or without a 
DHCP server, and describes how to acquire the NVS-31 MARK II’s IP address. 

Connecting to a DHCP Network (DHCP Mode) 

Follow the following procedure to scan your DHCP network for connected NVS-31 MARK II 
devices. 

Note: The NVS-31 MARK II will be automatically assigned an IP address upon connection 
to the DHCP network.  

1.

 

Connect  the  NVS-31  MARK  II’s  stream  port  to  the  network  via  an  Ethernet 
cable.  

2.

 

Turn on the KMU-200’s power and the NVS-31 MARK II will also be turned ON 
in the DHCP mode by default.  

3.

 

Connect the laptop to the same network that the  NVS-31 MARK II is connected to and 
download the free IP Finder utility program.  

4.

 

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

5.
