The GTW-VOA is a video output adaptor for the GT Series multi-tenant video entry system. The adaptor will convert the 2-wire video signal from the GT Series to a standard composite video output signal. This allows the video image from the entry panel to be seen on any standard CCTV monitor or TV (video input). The video can also be recorded if connected to a DVR or other recording device. The adaptor connects to the common video bus of the GT Series and will output video whenever any video call is active on the system. Datasheet GTW-VOA.
