KBW-M
Video Modulator for the KB Series Color Video System
- INSTRUCTIONS -
The KBW-M adaptor converts a standard CCTV camera's signal to a 2-wire signal, compatible with the
KB 3x5 Color Video system. This allows the utilization of a color camera on a video input on the KB
system, viewable from any monitor in the system. (A camera and KBW-M can be added to any input
that is not used by a KB-DAR video door station.)
