15.3 Multicast
The camera can enable multiple receivers to receive the video
signal simultaneously. The stream is either duplicated and then
distributed to multiple receivers (Multi-unicast), or it is sent as
a single stream to the network, where it is simultaneously
distributed to multiple receivers in a defined group (Multicast).
Multicast operation requires a multicast-enabled network that
uses UDP and the Internet Group Management protocol
(IGMP V2). The network must support group IP addresses.
Other group management protocols are not supported. The
TCP protocol does not support multicast connections.
A special IP address from 225.0.0.0 to 239.255.255.255
(class D address) must be configured for multicast operation in
a multicast-enabled network. The multicast address can be the
same for multiple streams, however, it is necessary to use a
different port in each case.
The settings must be made individually for each stream. Enter a
dedicated multicast address and port for each stream. Switch
between the streams by clicking the appropriate tabs.
15.3.1 Enable
Enable simultaneous data reception on receivers that need to
activate the multicast function. To do this, check the box and
enter the multicast address.
15.3.2 Multicast Address
Enter a valid multicast address to be operated in multicast
mode (duplication of the data stream in the network).
With a 0.0.0.0 setting, the encoder for the stream operates in
multi-unicast mode (copying of data stream in device). The
camera supports multi-unicast connections for up to five
simultaneously connected receivers.
