Video sources
The Northstar 972 can display video 
signals from a variety of sources. TV 
cameras, videotape, and DVD players all 
can display their images on the 972’s 
screen as long as the signals conform to 
NTSC or PAL standards.
Just connect the video source’s cable to 
one of the four BNC connectors on the 
back of the 972 black box, and the signals 
will be available for display. 
Video signals are not carried over the 
Ethernet network. A separate video cable 
must be run to each 972 system.
