The A1081 DoorBird I/O Door Controller offers tamperproof control of up to three doors or gates over a network. It can be installed in a protected interior area, such as a control cabinet in the basement and can be connected to the DoorBird IP video door station via the network. No physical wires have to be connected between the door or gate and the door station. The DoorBird I/O Door Controller therefore eliminates the risk of shorting and activating the electric door opener in case of unauthorized removal of the door station and makes your property/building safer. The connection of the DoorBird I/O Door Controller to the network can be accomplished via network cable (PoE cabability) or WIFI.
