Principle of operation
Detects broken glass using an electret microphone, which registers the sound of impact against the glass and of the glass falling.
Features
Two-factor detection of broken glass prevents false alarms caused by thunder, dogs barking and noise from passing trucks
Installation and set up
Ready to operate straight out the box: the battery is already installed, therefore there is no need to disassemble the detector. With one click, it can be connected to the hub in the mobile application. It can be mounted on the smart bracket in just a few minutes.
