Glass Break Detectors in Alarm Systems

Glass break detectors add an extra layer of security to alarm systems by picking up the frequencies of shattering glass. By listening for sounds rather than scanning motion. These devices can pick up more activity than cameras to protect every corner of your property.

Some detectors use shock sensors that identify abnormal vibrations in the glass. However, acoustic sound detection sensors are often the most efficient, affordable, and versatile with other security systems. Continue reading to learn how glass break detectors work and how they can integrate with your alarm system for more comprehensive protection.

Sound Detection

Glass break detection devices use microphones and other sensors to monitor windows and entrances for potential break-ins. The sensors are programmed to detect frequency patterns similar to shattering glass and other presets. When they detect an applicable sound, they send an alert of the potential intrusion to the rest of the alarm system.

Additionally, thanks to the detectors’ algorithms for analyzing acoustics, most sensors and devices can distinguish abnormal sound patterns from ambient noises. This way, storms, music, traffic, and other loud noises won’t create false alarms or block out glass breaks. 

Verification

False alarms are annoying and impair your sense of security, as you never know when an alert is another mistake or something serious. Glass break detectors’ verification systems help prevent false alarms by searching for multiple suspicious instances before signaling an alert. For example, the detection system may wait to hear the shattered glass hit the ground rather than raising the alarm at the first high-pitched sound. 

Different models and settings have different tolerance and frequency levels for sound verification. When combined with other security systems, such as 24/7 alarm monitoring, glass break detectors can appropriately verify most intrusions without sending false alerts.

Range and Coverage

The placement of glass break detectors is usually determined by their coverage and range — or how far they can pick up glass frequencies. Each sensor’s range is specified by its design, sensitivity settings, and nearby factors, such as being outside or next to a loud appliance. 

Detectors should be placed strategically to ensure all windows and other glass entry points are within at least one sensor’s coverage. A team of security professionals can help you determine the best glass break detection setup for your property.

Installation

Most glass break detection models must be installed differently from one another, usually detailed within the product packaging. While many products offer multiple installation options, it’s important to follow their instructions precisely or hire a professional to ensure proper orientation and security. 

Below are some of the most common locations to install glass break detectors:

• Inside the window frame
• Directly on the glass
• On the wall facing the window
• On the ceiling above the window
• On an unblocked shelf or another piece of furniture

Alarm System Integration

Glass break detectors easily integrate with most security alarm systems, depending on the model and brand. Upon picking up abnormal movement, the detectors alert the rest of your security system. 

Based on your settings, a confirmed incident of shattering glass could immediately set off loud sirens, lights, and other alarms. This will alert people on the property of the potential intrusion and usually scare trespassers off, especially with cameras present.

When you work with a security team with live video monitoring, a response expert at the central monitoring station will immediately receive the alert and investigate. They can alert you, contact the police, or mark it as a false alarm.

User Control

Most modern detection systems feature user control settings, including sensitivity, timers, and marking when you’re away from home. Adjusting sensitivity is important because it regulates range and how easily the detector will trigger an alarm. Higher sensitivity settings cause sensors to detect more noises at greater distances but may pick up too many sounds. Contrastingly, lower settings cause sensors to only detect noises within a five- to ten-foot range. 

These settings let you fine-tune sensors’ tolerance to noises in your environment and reduce false alarms. This is especially crucial for sensors near construction sites, ice machines, children playing with toys, and other noises similar to shattering glass. 

Upgrade Your Security Setup with Glass Break Detectors and More

Glass break detection systems are critical yet often overlooked aspects of home and business security. By detecting acoustic frequencies and letting you adjust settings, these devices let you cover more ground than cameras and secure your property more thoroughly. When integrated with dependable security and alarm services, such as Alarm Detection Systems, glass break detectors can further improve security, prevent break-ins, and keep you safe.
