The Vivint Glass Break Sensor

Cutting-edge protection in the most vulnerable places.

Get Instant Alerts the Moment a Window Breaks with Glass Break Sensors

When a window breaks in your home, it could mean an intruder’s not far away. But what if you’re not there to hear it? The latest GB2 Vivint Glass Break Sensor is your answer. Equipped with a high-frequency microphone and a 360-degree horizontal sensing angle, this wireless glass break sensor alerts you the moment glass forcibly breaks in your home.

While Vivint Smart Sensors notify you when a door or window opens, they won’t alert you if one breaks. So the Vivint Glass Break Detector adds that extra level of protection to round out the security of your Vivint smart home.

  • Tamper-proof switch
  • Instant alerts through the Vivint Smart Home® App
  • Two-way talk though the Vivint Smart Hub™
  • 360-degree horizontal viewing angle
  • Dual-shatter recognition

The Vivint Glass Break Sensor comes equipped with quality features for a home security boost you can trust.

Microphone Icon

High-Frequency Microphone

Packed with a 345 MHz audio microphone, the Vivint window break sensor detects the unique frequency of glass forcibly breaking while ignoring other sounds, so you can take action only when necessary.

Window Icon

Dual-Shatter Recognition

This window glass break sensor listens for two clear sounds—a thud and a shatter—to intelligently detect forced entry while avoiding a false alarm from your dog jumping up on the sliding-glass door.

Settings Icon

Three Sensitivity Settings

Vivint understands each room has variations and noise levels all its own. That’s why the glass break alarm offers low, medium, and high sensitivity settings that detect sound from 5, 10, or 15 feet away.

Frequently Asked Questions

How do you reset a Vivint Glass Break Detector?

Simply disarm your system, remove the batteries and wait 20–30 seconds, then re-insert the batteries. You’re all reset! Fun fact: you can change out your Vivint Glass Break Battery using the same method.

How do you test a Vivint Glass Break Sensor?

You can test your glass breakage detector in a couple easy steps. First, disarm your system via the Smart Hub™ panel and tap System Test under Menu > Security. This allows you to test your system without triggering a false alarm. Next, remove the cover of your wireless glass break detector and send a tamper signal to determine whether your device is communicating with your Smart Hub™ panel.

How do glass break sensors work?

Glass break detectors work by using a high-frequency microphone to listen for the distinct frequency of breaking glass. Once detected, the glass break alarm will notify you via the Vivint Smart Home® App.
