6.8.4Multicast
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
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.
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.
