You may choose to enable multicast for your camera audio and video streaming so that your cameras (sources) and the
receivers (clients) can establish the connection to send and receive contents.
Multicast group An IP Multicast group address is used to send and receive content. Sources use this group address as the destination
address:
address while sending their data packets. Receivers use this group address to inform the network that they are interested
in receiving packets sent to that group.
For example, if some content is associated with group 239.1.1.1, the source will send data packets destined to 239.1.1.1.
Receivers for that content will inform the network that they are interested in receiving data packets sent to the group
239.1.1.1. The receiver "joins" 239.1.1.1. The Multicast address ranges from 224.0.0.0 to 239.255.255.255, or, equivalently,
224.0.0.0/4
