Multicast Setup
The Multicast page allows recordings from the unit’s camera input to be forwarded to a port address;
enabling multiple viewers to view live data using a suitable media player without the need to directly
connect to the unit. In multi viewing scenarios, the demands on the unit are significantly reduced;
improving overall performance.
This system has been validated using the ‘Videolan VLC media player for MS Windows.
The Videolan VLC media player can be downloaded free of charge from:
www.videolan.org/vlc/download-windows.html
Please refer to Appendix E for guidance on configuring the Videolan VLC media player.
Note: Multicast can only used for live viewing, requests for stored images and events will still need to be
made via the Viewer menu.
Multicast Address
Assign a unique IP address. This address is not assigned to any ‘physical’
unit. The VLC program will use this address (when configured to do so) as
its multicast group and access any broadcast images via the configured port
address (see below).
If there are multiple units using multicast, each one must have a unique IP
address.
Multicast port
Following configuration of the IP address, configure the port address. The
address will default to 1234, .
Multicast Method
Select the multicast forwarding method. Select from ‘SAP’ (to use session
announcement protocol operation), ‘HTTP’ (to use using cgi control operation)
or ‘SAP+HTTP’ (both methods used simultaneously)
Enable
Tick this option to enable multicast.
