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 is done using a protocol ge
nerally referred to as Real-time Transport Protocol
(RTP), but there are actually many protocols involved, including Real-Time Transport Control
Protocol (RTCP) and Real Time Streaming Protocol (RTSP). The complete connection strings are:
rtsp://192.168.0.250:554/stream1 for Visible 1, rtsp://192.168.0.250:554/stream2 for V
is
ible 2, and
rtsp://192.168.0.250:554/stream3 for Thermal/Unified 1
By default the video stream uses the IP address of the camera. To
maintain compatibility with legacy
systems the stream names are aliased as: ch0 = stream1, ch1 = stream2, and ch2 = stream3.
Authentication is required when log
ging into the camera stream using any of the user/passwords
setup by an administrator (admin level login). Refer to Users Page.
