If necessary, select a different port for the exchange of the
RTSP data from the list. The standard RTSP port is 554. Select

6.8.3
Multicasting
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

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