ADT Wireless Glassbreak Detector
Glass Break Sensors are perimeter protection devices of a home security system.ADT Wireless Glassbreak Detector detects when glass is broken while the intruder is still outside.To provide glass-break protection for your windows and glass doors you must have a glassbreak sensor within 20-25 feet of all glass in the home. Also there must be a clear site line between the sensor and the glass. Therefore, glassbreak sensors will not detect broken glass through a wall or the next bedroom even if it’s less than 20 feet away.
