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 signicantly 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 B for guidance on conguring 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

congured to do so) as its multicast group and access any broadcast

images via the congured port address (see below).

If there are multiple units using multicast, each one must have a

unique IP address.

Multicast port Following conguration of the IP address, congure 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.
