By being strategically placed near windows or glass doors, it effectively alerts you in case of break-ins, giving you peace of mind whether you're in or away from your property. -
Question:
How does the glass break detection technology work?
Answer: The glass break detection technology of the Qolsys QS1431-840 utilizes sophisticated audio analysis that differentiates the sound of breaking glass from other noises in its environment.

Question:
