Here's the string format on how to access video from IP camera through RTSP

 

rtsp://<username>:<password>@<ip>:<port>/cam/realmonitor?channel=<channelNo>&subtype=<typeNo>

 

 

where:

<username>: a valid user’s username.
<password> :user’s password.
<ip> :the IP address of the Dahua video product.
<port >:the default port is 554. It can be omitted. It can be obtained in 5.10.1 GetRTSPConfig.
<channelNo> :the channel number. It starts from 1.
<typeNo> :the stream type. The <typeNo> of main stream is 0, extra stream 1 is 1, extra stream 2 is 2.The extra stream
counts can be obtained in 4.1.2 GetMaxStreamCounts. 
The stream must be enabled by setting head.VideoEnable to
true in 4.4.4 SetVideoEncodeConfig.

For example, we request the extra stream 1 of channel 1, 

the URL is:
rtsp://admin:admin@10.7.6.67:554/cam/realmonitor?channel=1&subtype=1.
