Sentrol Recessed ShatterPro II Glassbreak Sensor

Don't sacrifice style for security! Protect your home with a recessed glassbreak sensor that unobtrusively mounts into a ceiling or wall. This sensor triggers an alarm signal when it hears the sound of breaking glass. It's ideal for safeguarding areas in your home with multiple windows, even if the doors and windows are protected by contact sensors. For example, if a burglar throws a rock through your sliding glass door, contact sensors won't set off the alarm system, but this glassbreak sensor will. The sensor detects in a full 360° coverage pattern with a 25' radius range. Pattern Recognition Technology provides superior detection and exceptional false alarm immunity. Mounts in a 1" hole for attractive, unobtrusive appearance, and connects to hardwired security systems via four-conductor cable. Trim ring included.
