The Alarmtech AD800-AM sensor detects the breaking of ordinary, tempered, and laminated glass, protecting against break-in attempts through windows and glass panels in walls or doors. Digital acoustic space compensation (DRC) distinguishes the sound of breaking glass from other sounds. It features active anti-masking protection and dual-channel microphone tamper detection, using an acoustic AM signal at frequencies inaudible to humans and infrared (IR).
