These glass-break detectors are called also “Audio Discriminators”. They are different from the motion detectors because they prevent burglars from entering in the house and not when they are already inside. They can be found on the market either in hardwired or wireless versions.
- In the case of an open concept kitchen, breakfast nook and family room, the glass-break detector can cover every window because of the fact that they are in the area of 35 feet.
- For a living room is simpler than the previous one because all the windows are in same room and consequently in the same area and a single device is more than enough. This one can be used even for the dining room.
- It’s possible to have a basement that has not been finished and with many windows. In order to protect this area you can simply use a glass-break detector.
These glass break detectors work based on the frequency of broke glass and includes also splintering wood. A few years back, the only glass break detectors available were the “Single Technology” ones. They worked on the same principle, but their sensitivity was very high. In the case of a light crack, sneeze, clank of two glasses, the detector would have caused a false alarm and only the best detectives could have found the cause.
These single technologies are still used today, but a buyer who is preoccupied with its house safety will insist for a “Dual Technology” device. These new devices are more precise and it is needed for both a “Thump” and a frequency hit to trigger the alarm. A good example for you to understand is that in which you sneeze and in the same time your bird pet lets out a squawk, which results in a bang with your head on the wall. If the alarm would be armed, these events wouldn’t make it go off because you should have banged your head on the wall first, in order for that to happen. This advancement in the security systems technology has created something on which you can count on when it comes to protection.
One thing that can discourage you is the price of the sound discriminator, because if you install such a system in your house you need one of these in each room. The best way to keep the costs as low as possible is to place the devices in the areas with the highest risk and back them up with a motion detector placed at the main floor. Taking this advice will help you save some money and spend all of them in turning your house into a Fort Knox.
