In addition to a one-to-one connection between a camera and a 

single receiver (unicast), the camera can enable multiple 

receivers to receive the video signal simultaneously. This is 

either done by duplicating the data stream in the device and 

then distributing it to multiple receivers (multi-unicast), or by 

distributing an individual data stream in the network itself to 

multiple receivers in a defined group (multicast). Enter a 

dedicated multicast address and port for each stream. Then 

switch between the streams by clicking the associated tabs.

The prerequisite for multicast operation is a multicast-capable 

network that uses the UDP and IGMP protocols. Other group 

membership protocols are not supported. The TCP protocol 

does not support multicast connections.

A special IP address (class D address) must be configured for 

multicast operation in a multicast-enabled network. The 

network must support group IP addresses and the Internet 

Group Management Protocol (IGMP V2). The address range is 

from 225.0.0.0 to 239.255.255.255. The multicast address can 

be the same for multiple streams. However, it is then necessary 

to use a different port in each case so that multiple data 

streams are not sent simultaneously using the same port and 

multicast address. The settings must be made individually for 

each stream.

Enable simultaneous data reception on several receivers that 

need to activate the multicast function. To do this, check the 

box and then enter the multicast address.

Enter a valid multicast address to be operated in multicast 

mode (duplication of the data stream in the network). With the 

setting 0.0.0.0 the encoder for the stream operates in multi-

unicast mode (copying of data stream in device). The camera 

supports multi-unicast connections for up to five 

simultaneously-connected receivers.
