Glass Breakage Alarm Sensors

Our Glass break sensors have in the past had a varied history. You may have seen foil-based sensor systems on windows in the past which triggered when the foil was broken. These are now considered unsightly and are time consuming to install. Other systems employed sound detection which went off when the sound of breaking glass was detected. However these were susceptible to false alarms. Today we use a dual sensor that detects the sound of breaking glass and then 'listens' for the pressure wave given off by the break.
