Quality of service
The priority of the different data channels can be set by defining the DiffServ Code Point
(DSCP). Enter a number between 0 and 252 as a multiple of four. For alarm video you can set
a higher priority than for regular video and you can define a Post Alarm Time over which this
priority is maintained.

Multicast page
In addition to a 1:1 connection between an encoder and a single receiver (unicast), the device
enables multiple receivers to receive the video signal from an encoder simultaneously.
The device either duplicates the data stream itself and then distributes it to multiple receivers
(Multi-unicast) or it sends a single data stream to the network, where the data stream is
simultaneously distributed to multiple receivers in a defined group (Multicast). You can enter a
dedicated multicast address and port for each stream.
The prerequisite for multicast operation is a multicast-capable network that uses the UDP and
IGMP protocols. Other group management 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 the same multicast address.
Note: The settings must be done for each encoder (video input) and for each stream
individually. The numbering follows the labeling of the video inputs on the device.
Enable
To enable simultaneous data reception on several receivers you need to activate the multicast
function. To do this, select the check box. Then enter the multicast address.
Multicast Address
Enter a valid multicast address for each stream from the relevant encoder (video input) 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 the device). The device supports multi-unicast connections for up
to five simultaneously connected receivers.
Note: Duplication of data places a heavy demand on the device and can lead to impairment of
the image quality under certain circumstances.
Port
Assign a different port to each data stream if there are simultaneous data streams at the same
multicast address.
Enter the port address of the required stream here.
