Glass break sensors are effective at monitoring windows and protective glass casings.  These sensors have a special dual-sound detection process allowing an alarm to be sent at the sound/frequency of breaking glass, but preventing false alarms on the security system.  These are great for adding additional layers of defense to your home or business security system.
