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.

NOTE

► To utilize the RTSP streaming authentication, make sure that your have set a password for the

Network Camera ﬁrst; please refer to Security on page 22 for details.
