Diagram I – Camera Sharing & Time Clock Sharing
Camera Termination Options
Cameras may be wired in either twisted pair or coax and shared with other equipment.
Time Clock Sharing
A time clock can be shared between distributed equipment areas by borrowing one of the
‘comm -’ wires in the interconnecting Cat5 to use as the shared “Time clock common”.
The “Time clock common” signal is sharable across all Bell controller types.
