The Doorbird A1081 I/O Door Controller offers the ability to securely control up to three doors or gates over the network. In most cases, electric door openers are directly connected to the door station via two wires due to structural reasons. Unauthorized removal of the door station and intentional short-circuiting of the wires can activate the electric door opener, allowing unauthorized individuals access to the property or building. The Doorbird Door Controller provides a solution, as it is installed in a protected indoor area, such as a control cabinet in the basement, and is connected to the Doorbird IP video door station via the network. The connection to the network can be made via LAN or WLAN.
