106 en Advanced Mode FlexiDomeHD 720p IP Camera

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.
