The 2112 is a video entry system designed for residential applications. With the DKS 2112 app and a smartphone, homeowners can see who is at their front door or gate and easily grant or deny them entry, and they can lock their door or gate open as needed. With the broadcast calling feature, up to four (4) phones will ring when the call button is pressed. The 2112 can control up to three (3) entry points and uses an internet or cellular connection.
