To keep your building secure from burglars and other intruders, shop AUTHORIZid’s selection of contact sensors. When your place of business closes for the night, nobody should be going in or out. To monitor any unwanted movement, mount door alarm sensors to all the doors you want to secure. It’s an easy setup—many of our commercial door contacts can be surface mounted.

With AUTHORIZid’s door alarm systems and even window alarms, you’ll sleep soundly at night knowing your building is secure. Install our commercial door contact sensors, which are recessed into doors that are normally closed (N.C.), and the magnetic alarm will go off when somebody tries to open the doors.
