Network Options
By default, multicast is enabled. Multicast video packets are shared by streaming clients. Additional clients
do not cause bandwidth to increase as dramatically as with unicast. Video stream requests for ch0/stream1
are unicast. Client-specific multicast requests vary according to the client.
If more than one camera is providing multicast streams on the network, make sure the Destination Network
IP address is unique for each camera (the Destination Port can be reused). By default, the port
assignment is unique per stream.
The time-to-live field controls the ability of IP packets to traverse network boundaries. A value of 1 restricts
the stream to the same subnet. Greater values allow increasing access between networks.
The video streaming uses a protocol generally referred to as RTP, the real-time transport protocol, although
there are actually a number of protocols involved, including the Real-Time Streaming Protocol (RTSP). The
video stream URLs incorporate the IP address of the camera. Using the camera's default IP address, the
complete URLs are:
·
Visible 1—rtsp://192.168.0.250:554/stream1
·
Visible 2—rtsp://192.168.0.250:554/stream2
·
Thermal 1—rtsp://192.168.0.250:554/stream3
To maintain compatibility with legacy systems, the stream names are aliased as: ch0 = stream1, ch1 =
stream2, and ch2 = stream3.
Accessing any of the camera's video streams requires authentication. You can use the name and
password for any of the camera's users. See Users Page.
