Home Security – Glass Break Detectors

The greatest degree of home security is often achieved through utilizing a combination of products. Glass break detectors, along with security lighting, sturdy locksets, motion detectors and security cameras are examples of options currently available. Preventing intrusion altogether is certainly the first priority, however detecting an attempted intrusion and thwarting that effort is also critical. Glass break detectors or “audio discriminators” will immediately warn of an attempted invasion.

Glass break detectors should be placed in any room that would be susceptible to entry thorough a window or glass door. Installation should not be limited to rooms on the ground floor; basements and second floor windows should also be considered. The units are typically mounted on the wall or ceiling and are available in either “wired” or “wireless” varieties. The technology does not allow the unit to “hear” through walls, ceilings and closed doors or around corners. Consequently, it will normally be necessary to install one unit per room.

The most basic detectors, sometimes referred to as “single technology,” are triggered by the sound of glass breaking or wood splintering. Although they do serve their purpose, due to their primitive technology, they often will trigger a false alarm. Many non-intrusion related noises generate a sound frequency which will trigger a false alarm. Some of these include: lightning, inadvertently dropped items, a wooden chair breaking or a dropped drinking glass. Although somewhat antiquated, “single technology” units are still available for purchase and even being utilized by some alarm companies. They tend to be less expensive than currently available state-of-the-art units.

Although a more costly alternative, newer technology is now available. All things considered you should probably opt for the newer product, often called “dual technology.” This type of audio discriminator must recognize two distinct actions in order to activate. First it must detect a thumping noise and that must be immediately followed by a break (frequency triggering noise). This two-step process is highly efficient and eliminates the vast majority of false signals.

Relatively speaking, when considering installing glass break detectors throughout a home, it can be an expensive proposition. Though prices vary, dual technology units can cost upwards of $100 apiece. However, bear in mind that by enhancing your home’s security you should be eligible for a reduction in your homeowner’s insurance. The recurring savings will definitely help to offset the initial cost of equipment.
