A glass break detector is a perimeter security device that can be used to alert you when a burglar breaks in a window in order to gain entry into your home or business. Such home or business alarms are typically small in size, and are designed to be installed on the ceilings or walls near all external windows that provide access to the interior of a building. A glass break detector can be set to generate either an audible alert or a silent alarm when it detects that someone has shattered a window pane in order to break into your property.
How Glass Break Sensors Work
A glass break detector is often also referred to as an ‘audio discriminator’ because it detects intrusions based on the sound of cracking or shattering glass. Most modern sensors are capable of detecting the sound of breaking glass from distances of up to 35 feet away. The sensors are programmed to listen for the frequency of the sound that glass makes when it is broken or cracked.
Some glass breakage sensors are ‘single technology’ devices that are designed to issue alerts based solely on the sound of breaking glass. Such devices are relatively inexpensive, but they are also prone to false alarms because they often mistake other sounds with the sound of glass breaking. State of the art sensors use ‘dual technology’ to detect glass breaks. They are programmed to respond only when they hear a specific sequence of sounds associated with glass breakage.
Wired and Wireless Sensors
A glass break detector can either be a wired sensor or part of a wireless alarm system. When such detectors are deployed in a wired fashion, they usually connect back to a central security console. When a wired sensor detects a break-in, it sends a silent alarm to the central console, which, in turn, immediately notifies a security monitoring center of the intrusion. Wired glass breakage sensors are usually deployed by security companies as part of a broader set of burglar monitoring services.
A wireless glass break detector is largely designed for do-it-yourself installation, though it can also be used as part of a monitored service. Wireless sensors usually generate loud alarms that are designed to alert the occupants of a building of an intrusion, while also scaring away would-be burglars.
Ideal for Homes
Glass breakage sensors are ideal for homes with many windows. Because such sensors provide coverage for an area of around 35 feet, you need to install only a few strategically placed sensors in order to protect your entire home. Many homes, for instance, have breakfast nooks, family rooms and open kitchens that are adjacent to each other. By installing a single glass break detector, you can protect all the windows in these three areas. Glass breakage sensors are also ideal for walk-out basements, unfinished basements or basements with windows. A single breakage sensor is often sufficient to protect the entire area.
Improved Security with Little Investment
You can purchase a decent wireless breakage sensor for less than $75 these days. Many such devices can communicate with a central alarm panel from distances of up to 300 feet away. Modern dual technology sensors are programmed to generate an alert only when they hear a distinct thud followed by the crash of breaking glass. Most sensors are battery powered and come with rechargeable batteries that can be charged from standard power outlets.
If you have signed up for glass breakage protection with your security monitoring company, insist on having dual-technology sensors installed in your home. A glass break detector can significantly boost the security of your home and is well worth the relatively small investment it takes to install such devices in your home.
