Installation and Operation Manual
Bosch Security Systems
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.
Duplication of data places a heavy demand on the CPU and can 
lead to impairment of the image quality under certain 
circumstances.
Port
Enter the port address for the stream here.
Streaming
Click the checkbox to activate multicast streaming mode. An 
activated stream is marked with a check. (Streaming is typically 
not required for standard multicast operation.)
Multicast packet TTL
A value can be entered to specify how long the multicast data 
packets are active on the network. If multicast is to be run via a 
router, the value must be greater than 1.
