44D-Link DCS-3415 User Manual
Section 4 - Configuration
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
Default port number is 5560, or please choose between 1024 and 65534.
Default port number is 5561, or please choose between 1024 and 65534.
Default port number is 5563, or please choose between 1024 and 65534.
Set a Time to Live (TTL) value for multicast packet, please choose between 1 and 255.
The two way audio port in DSC-3415 is set to 5060, by default. It can also be assigned to another port number between
1025 and 65535.
This Network Camera supports two way audio communication so that operators can transmit and receive audio simultaneously.
By using the camera’s built-in microphone and an external speaker, users can communicate with people present around the
Network Camera.
Note: Since JPEG only transmits a series of JPEG images to the client, to utilize this feature, make sure the video mode is
set to MPEG-4 and the media option is set to Video and Audio.

Two way audio port:
Unicast video transmission delivers a stream through point-to-point transmission. On the other hand, multicast video
transmission 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 is the multicast RTP port number plus one, and thus always be odd. When the multicast RTP port
changes, the multicast RTCP port will change accordingly.
