The Doorking 1812 Telephone Entry System is a unique telephone intercom system that allows property owners to use their telephone as an intercom to speak to a visitor at the gate without the necessity to pay for an additional telephone line at their home.

With its "intercom mode" programming feature, the 1812 can also be connected to a PBX or KSU type system, making it ideal for small businesses to control access through a single door or gate. Visitors are easily identified by voice communication and can be granted or denied access directly from a touch-tone telephone. It also allows for 50 programmable 4 digit key codes.

The 1812 includes the DKS auto-programming software for Windows, allowing homeowners to program the system right from their home computer.
