Know the Moment a Door or Window Opens
An unlocked door, an open window, or an unnoticed entry can leave your home, office, hotel room, or storage area vulnerable.
The Wireless Magnetic Door & Window Alarm Sensor detects when two protected surfaces are separated, helping alert you when a door or window is opened.
Compact, lightweight, and easy to integrate into compatible alarm setups, it adds an extra layer of awareness without bulky equipment or complicated daily operation.
