Now you can answer your door or gate from the safety of your telephone! The W-1000 (flush mount) and W-2000A (surface mount) doorboxes are designed to be installed on the unused telephone line input of nearly any phone system. One or two doorboxes can also share an existing residential phone line and provide door strike and CCTV camera control when used in combination with a C-1000B doorbox controller.
When the "Call" button is pressed, the doorbox generates a standard ring cadence for an adjustable number of rings. To converse with the visitor, the inside party simply answers the call from the phone of their choice.
