3.5.4 Streaming
RTSP is a streaming control protocol, and a starting point for negotiating transports such as RTP,
multicast and Unicast, and for negotiating codecs. RTSP can be considered a "remote control" for
controlling the media stream delivered by a media server. RTSP servers typically use RTP as the
protocol for the actual transport of audio/video data.
RTSP Port Choose the RTSP port. The RTSP protocol allows a connecting client to start
a video stream. Enter the RTSP port number to use. The default value is 554.
RTP Port Specify the range of transmission port number of video stream. The default
range is 50000 to 50999. User can specify a number between 1024 and
65535.
To use the 3GPP function, in addition to previous section, you might need more information or
configuration to make this function work.
NOTE: 1. The camera must be set as Multi-profile mode, not Mega-pixel mode. Otherwise
this device cannot serve 3GPP stream.
2. To use the 3GPP function, it strongly recommends installing the Networked
Device with a public and fixed IP address without any firewall protection.
RTSP Port Port 554 is the default for RTSP service. However, sometimes, some service
providers change this port number for some reasons. If so, user needs to
change this port accordingly.
