Configuration
Access name for stream 1 ~ 5:
This Network Camera supports multiple streams simultaneously. The access name is used to differentiate the
streaming source. If you want to use an RTSP player to access the Network Camera, you have to set the video mode to H.264 / MPEG-4 and use the
following RTSP URL command to request transmission of the streaming data.

• The

By default, the RTCP port for video is set to 5557 and the RTCP port for audio is set to 5559.
The ports can be changed to values between 1025 and 65535. The RTP port must be an even number and the RTCP port is the RTP port number
