Video Modulator with Audio Door Station and CCTV Interface
- INSTRUCTIONS -
The KCW-M adaptor converts a standard CCTV camera's signal to a 2-wire signal, compatible with the KC 1x3
Color Video system. This allows the utilization of a color CCTV camera and a separate audio door station (JA-D)
to be used in place of a KC-DAR video door station. The CCTV camera can also be connected to a standard
CCTV system for continual viewing and/or recording. The unit is equipped with a relay output to trigger an
external device, such as a DVR or video switcher whenever the audio and video to the Aiphone monitor is on.
