Glass sensors have come a long way over the years. The original method used to protect glass was a conductive metallic tape or foil that was applied directly to the glass. If the glass were broken, the cracks would cause the foil to break.
While this was a reliable method of detecting glass breakage, it was labor intensive to install and prone to extensive service from scratches and breaks in the foil.
Today, most glass break sensors are acoustic devices that are visually attractive, less expensive to install and maintain and can be set to trip to only the sound of breaking glass. Newer models of quality glass sensors are less prone to false alarms.
Glass sensors do not actually sense glass breaking; they listen for a frequency of sound caused by the crash or crack associated with breaking glass. Therefore, it is important to have glass sensors installed by trained professionals.
The number one brand for this type of device is Sentrol that, when they are installed correctly, will give you the protection you need with no false alarms. However, glass sensors should not be installed in a room where there is normally a lot of noise, such as a kitchen.
The kitchen may be a good location for a glass sensor when you are not home. But if the system is on when you are home, any glass touching, breaking or clanging will set off the alarm. If you decide to install glass sensors in your kitchen, they should be activated only when you are away from the home or not in the room.
