DCS camera gateway Features: The DCS-camera gateway integrates a common analogue camera into the Gira door communication system. The camera can be assigned to a door station. In this case, the external camera switches on automatically when the call button is pressed. The combination housing of the DCS-camera gateway makes three mounting types possible:: Surface-mounted (in a standard junction box). Flush-mounted (in a device box). As a DRA device (with the included DRA adapter) Notes : With several external cameras, a DCS-camera-gateway and a separate power supply is required for each external camera. Up to ten DCS-camera gateways can be used in a system, although the video signal may only run through a maximum of three DCS-camera-gateways. The external camera is connected with screw terminals.
