The port number that you use for RSTP streaming, the default port number is 554. RTP (Real Time Protocol) Port is used to streaming
audio and video while RTCP (Real Time Control Protocol) port is used to monitor QoS of RTP stream.
Note: RTP video port and RTP audio port must be an “even” number. The numbers of RTCP video port and RTCP audio
port must equal to the numbers of RTP video port and RTP audio port, plus one repetitively
Default port number is 5556.
Default port number is 5557.
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.
An IP Multicast group address is used to send and receive content. Sources use this group address as the destination 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
