TKS camera gateway Features: The TKS camera gateway integrates a standard analog 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 TKS camera gateway allows three types of installation: Surface-mounted (in a standard junction box). Flush-mounted (in a device box). As a REG device (with the included REG adapter) Notes: If there are several external cameras, a TKS camera gateway and its own power supply are required for each external camera. Up to ten TKS camera gateways can be used in a system, whereby the video signal can pass through a maximum of three TKS camera gateways. The external camera is connected via screw terminals.
