DoorKing of Inglewood, Calif., releases the 1812 Series wireless adapter for telephone intercom systems.
Designed as a plug-and-play device, the product connects to any DoorKing 1812 Series telephone intercom system, and the user's router and two-line telephone. The second telephone line provides full-duplex voice communication wirelessly from the home to the access point. By using an IP addressable camera, video can also be transmitted from the access point to the home.
The wireless adapter, which has range up to 1,000 feet, eliminates the need to trench for wire runs. Additionally, up to three access points can be used simultaneously with the product, according to the company.
