HTTP
Setting Description Default

80
RTSP Streaming
The VPort 251 supports standard RTSP (Real Time Streaming Protocol) streaming, which means
that all devices and software that support RTSP can directly acquire and view the video images
sent from VPort 251 without any proprietary codec or SDK installations. This makes network
system integration much more convenient. For different connection types, the access name is
different. For UDP and TCP streams, the access name is udpStream. For HTTP streams, the
access name is moxa-cgi/udpStream. For multicast streams, the access name is multicastStream.
You can access the media through the following URL: rtsp://<IP address>:<RTSP
port>/<Access name> for software that supports RTSP.
Setting Description Default
RTSP Port
An RTSP port is similar to an HTTP port,
which can enable the connection of
video/audio streams by RTSP.
