This is the ideal add-on box for an additional entryway to your home, connecting to your Doorbell Fon Door Answering System, which allows you to talk to visitors at the door over your telephone.
The Electric Lock Controller will enhance the Doorbell Fon system by providing a dry contact closure when you hit the star (*) key on the telephone. This allows you to trigger a doorstrike, unlocking a door or gate after answering the door intercom call.
Safely view and communicate with visitors who arrive at the front door while you remain in the confines of your home or business. The DP-222Q Enforcer Color-Video Door Phone establishes communication both verbally and visually with a person at your door.
