Summary

NVRs can use different profiles according to streaming purposes. When trying to view a specific stream of NVR through RTSP, determining which profile to look for is not clear. At this time, through the following CGI command, you can easily check the streaming profile number for each channel. This article describes how to check the streaming profile for each channel. 

Obtaining Profiles of Every Channel in NVR

To get every profile of every channel in the NVR:

1. Enter the CGI command:
   
   /stw-cgi/media.cgi?msubmenu=videoprofilepolicy&action=view
   
   Result sample:

    Channel.2.NetworkProfile=6
    Channel.2.LiveProfile=3
    Channel.2.RecordProfile=2
    Channel.2.LiveMode=Auto

    Channel.3.NetworkProfile=4
    Channel.3.LiveProfile=4
    Channel.3.RecordProfile=3
    Channel.3.LiveMode=Manual

    Channel.5.NetworkProfile=5
    Channel.5.LiveProfile=5
    Channel.5.RecordProfile=3
    Channel.5.LiveMode=Manual

Getting Stream RTSP

To get Stream RTSP:

1. Enter the following RTSP command: 

  rtsp://<ip_addr>:<last Device Port>/LiveChannel/<Channel Number>/media.smp/profile=<num>

NOTE: The device port is the last device port. The Channel Number starts 0. 
Therefore, Channel 1 of NVR is 0, Channel 2 of NVR Is 1 in rtsp.

Every profile of the connected camera can be used in the RTSP streaming address.

Profile information of NVR

• NetworkProfile - NVR path: Setup > Network > Live Streaming
• LiveProfile (& LiveMode) - NVR path: Setup > Device > Camera > Live Setup
• RecordProfile - NVR path: Setup > Record > Record Setup > Camera

Getting Stream URI

Stream URI can be obtained from the NVR through the following CGI. The CGI works for some profiles, which are used in the NVR only.

http://<ip_addr>/stw-cgi/media.cgi?msubmenu=streamuri&action=view&Channel=0&Profile=2&MediaType=Live&Mode=Full&ClientType=PC&StreamType=RTPUnicast&TransportProtocol=TCP&RTSPOverHTTP=False

Example response:

URI=rtsp://<ip_addr>/LiveChannel/0/media.smp/profile=2
