Get Alerted the Moment a Window Breaks
Enhance entry protection with ADT-monitored glass break sensors.

Windows Are Easier to Break Than Doors
Windows let gorgeous natural light into your home—but if a kid can break a window with just a projectile baseball, a burglar can find a way too. Add ADT-monitored glass break sensors to your plan to get backup for your door and window sensors and supplement your overall security system. Read below to learn how the glass break sensor works and how it can help you feel safer at home.

How the ADT-Monitored Glass Break Detector Works
The glass break detector monitors what your basic door and window opening detectors can’t—when a window is shattered rather than jimmied open. It uses two internal tools to accomplish this: a microphone, which picks up on noise or vibrations coming off the glass, and an electromechanical shock sensor, which measures physical forces applied to your windows. If these sounds or vibrations pass a certain threshold, the sensor will trigger your alarm system, notifying an ADT monitoring center immediately—and hopefully sending the burglar running.

Included in the Price of Your Plan
ADT door motion sensor and window motion sensor options are included in every ADT-monitored home security plan, even the most affordable priced at $36.99/mo, so every home has the best chance of covering key entry points. Plus, you’re always welcome to add additional sensors. When you order, or even during installation, professional security experts can help you decide on the best number and placement of sensors for your home.
Monitor More Than One Window at a Time
The ADT glass break alarm sensor has amazing features like tamper proofing, a sophisticated electro-mechanical shock sensor, two serial numbers for backup, and reliable 433 MHz wireless communication. And on top of all this, it can monitor multiple windows at the same time—its internal sensors can pick up on disturbances to glass surfaces within a 25-foot range. For you, that translates to fewer devices cluttering your home and lower equipment costs.
