RTP port for video
—RTP is used to deliver video and audio data to the
clients. By default, the RTP port for video is set to
5556
and the RTP port for
audio is set to
5558
. Change the port number if more than one camera is
doing multicast and using the same default IP address.
•
RTCP port for video
—The Real-time Transport Control Protocol (RTCP)
allows the Cisco VC 220 network camera to transmit data by monitoring
Internet traffic volume. By default, the RTCP port for video is set to
5557
and the RTCP port for audio is set to
5559
. It must be the port number of
video RTP, plus 1. Change the port number if more than one camera is doing
multicast and using the same default IP address.
•
RTP port for audio
—The audio channel port for RTP. It must be an even
number. Change the port number if more than one camera is doing multicast
and using the same default IP address.
•
RTCP port for audio
—The audio channel port for RTCP. It must be the port
number of audio RTP, plus 1. You can modify the multicast setting for
Stream 1 and Stream 2. Change the port number if more than one camera is
doing multicast and using the same default IP address.
NOTE
You can reassign the five ports to any value between 1024 and 65535. The RTP
port must be an even number and the RTCP port is the RTP port number plus one,
and is always an odd number. When the RTP port changes, the RTCP port will
change accordingly.
