RTSP port /RTP port for video, audio/ RTCP port for video, audio

The RTSP (Real-Time Streaming Protocol) controls the delivery of streaming media. By default,

the port number is set to 554.

The RTP (Real-time Transport Protocol) 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.

The RTCP (Real-time Transport Control Protocol) allows the Network Camera to transmit the

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.

The five ports can be changed between 1025 and 65535. The RTP port must be an even

number and the RTCP port is RTP port number plus one, and thus always be odd. When the

RTP port changes, the RTCP port will change accordingly.

If the RTP ports are incorrectly assigned, the following warning message is displayed:

Multicast settings for stream 1 / Multicast settings for stream 2

: Select the Always multicast to

enable multicast for stream 1 or stream 2. Unicast video transmission delivers a stream

through point-to-point transmission; multicast, on the other hand, sends a stream to the

multicast group address and allows multiple clients to acquire the stream by requesting a copy

from the Multicast group address.

The five ports can be changed between 1025 and 65535. The multicast RTP port must be an

even number and the multicast RTCP port number is the multicast RTP port number plus one,

and thus it is always be odd. When the multicast RTP port changes, the multicast RTCP port

will change accordingly.

If the multicast RTP video ports are incorrectly assigned, the following warning message is

displayed:

Multicast TTL [1~255]:The multicast TTL (Time to live) is the value that tells the router the

range a packet can be forwarded.
