A glass break sensor is designed to detect the sound frequency of breaking glass, such as a car window being smashed. If it detects this sound frequency it will trigger the alarm.
This sensor is one of the most common and popular ways of helping to protect the cabin of the vehicle.
AVS offers two kinds of glass break sensor:
Intelligent glass break sensor
Not only does it detect the sound frequency of breaking glass it also needs to detect an impact to the vehicle in order to trigger. This reduces false alarms from other similar sounds (such as a rubbish truck driving by with glass bottles inside or someone putting out their recycling bin).
Standard glass break sensor
It can be added as an optional upgrade to any 12 volt AVS car alarm.
