The DoorKing 1812-087 is a unique telephone intercom system that allows homeowners to use their telephone as an intercom to speak to a guest at a front door or gate without the necessity to pay for an additional telephone line at their home. With its "intercom mode" programming feature, the DKS 1812-087 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.
Use the simple and easy plug-and-play DKS Cellular option for voice only connection to the 1812-087 entry systems. No phone lines or internet cables to run - no trenching or conduits to install. And, of course, DKS telephone entry systems are all compatible with the traditional POTS copper wire.
