Use Network Setting > Multicast to send a stream to a multicast group address.
Multicast allows multiple clients to acquire the stream at the same time by
requesting a copy from the multicast group address, saving Internet bandwidth.
Multicast can be set per video stream. When you complete the multicast
configuration, click Save to save the settings; otherwise click Cancel to discard
the changes.
• Always Multicast—Select this option to enable the multicast function of the
camera so that you can deliver information from your camera to a set of
receivers.
• Multicast Group Address—The camera's video and audio IP address has
been pre-configured and can be used for multicasting. This does not
normally need to be re-configured. If an address does need to be changed,
contact your network administrator. To change, enter the Video Address/
Audio Address in the field provided.
• Multicast Video and Audio Ports—The camera's video and audio ports
have been pre-configured for multicasting. They do not normally need to be
re-configured. If a port number does need to be changed, contact your
network administrator. To change, enter the Video Port/Audio Port numbers
(between 1024 to 65534) in the fields provided. The Video Port/Audio Port
numbers you enter must be even values.
If there are multiple cameras that use the same default group multicast IP
address, modify the Video Port and Audio Ports to be a unique value.
• Multicast TTL [1-255]—Defines the number of hops (the number of
network routers that can be passed before the multimedia data packets
arrive at their destination or are dropped) that can occur before the packets
are dropped. A value in the range of 1 to 255 can be defined. The default
value is 15.
