stream in the unit 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). You can enter a dedicated multicast
address and port for each stream. You can switch between the streams by clicking
the associated tabs.
Note
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.
Multicast address video 1
Enter a valid multicast address for each stream to be operated in multicast mode
(duplication of the data streams in the network). With the setting 0.0.0.0 the
encoder for the relevant stream operates in multi-unicast mode (copying of data
streams in unit). The camera supports multi-unicast connections for up to five
simultaneously connected receivers.
Note
Duplication of data places a heavy demand on the CPU and can lead to
impairment of the image quality under certain circumstances.
Port
If there are simultaneous data streams at the same multicast address, you must
assign different ports to each data stream. Enter the port address for the relevant
stream here.
