What is a Glass Break Detector?


A glass break detector is a sensor used in burglar alarms that detects if a pane of glass is shattered or broken. These sensors are commonly used near glass doors and windows to detect if an intruder broke the glass and entered. Glass break detectors usually use a microphone, which monitors any noise or vibrations coming from the glass. If the vibrations exceed a certain threshold the alarm sounds and the alarm monitoring station is alerted.
