Entry Sensors

Watch every door and window.

The majority of burglars break in through a door or window. Our super-small Entry Sensor was designed with a tiny magnet to detect when one opens. When the magnet moves more than two inches away from the sensor, it sounds the alarm. With professional monitoring, it alerts our monitoring center who will dispatch police if there’s an emergency.

Entry Sensors can also be used to keep an eye on cabinets, safes and more. Secret Alerts quietly alert you if someone accesses private areas, without sounding an alarm.
