- INSTRUCTIONS -
The MKW-M adaptor converts a standard CCTV camera's signal to a 2-wire signal, compatible with the MK-1GD,
MK-2MCD, and MY series Black & White Video systems. This allows the utilization of a black & white CCTV
camera and a separate audio door station (JA-D)* to be used in place of an MK video door station. A motion
detector or other activation device can be connected to the Sensor input to trigger the system. 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.
