What is a Glass Break Sensor?

What is a Glass Break Sensor?

Glass break sensors actively listen for the breaking, cracking or shattering of glass around your home — such as windows and doors. Once the sensor detects the vibration of broken glass, it will sound a high-decibel alarm to alert you. Some glass break sensors that are professionally monitored will alert monitoring specialists to alert emergency responders to your home if the sensor is triggered.

Best Features to Look for in a Glass Break Sensor

Best Features to Look for in a Glass Break Sensor

  • Microphone with microprocessor

    Together, these features analyze the frequency, intensity and timing of glass breaking sounds. They’re able to detect the sounds at a heightened level and can even detect softer glass breaking sounds. These types of glass break sensors have minimal false alarms.

  • Clear indicators

    A glass break sensor should clearly alert you when the sensor has been tampered with or when it has a low battery. Look for glass break sensors that show an LED light, sound a high-decibel alarm or send a mobile notification to alert you to check the status of the sensor

  • Sensitivity settings

    The best glass break sensors allow you to adjust the sensitivity to prevent false alarms. Some allow you to select from one of the built-in preset options to determine whether or not the sensor detects the softest glass breaking or more loud and intense shattering. For the best range or options, look for sensors that have at least four settings.

Factors to Consider Before Buying a Glass Break Sensor

Factors to Consider Before Buying a Glass Break Sensor

  • Range – Look for a glass break sensor that has a wide range. Most glass break sensors can detect broken glass within 20-25 feet from the sensor from 360-degrees. The wider the range, the less glass break sensors you’ll need because one sensor can detect broken glass in multiple other rooms within range. The glass break sensor microphone will pick up noises even through walls and doors, but to make the most of your sensor’s range, place it in an open area with very few walls or doors blocking it.
  • Monitored security – Glass break sensors connected to a fully monitored home security system helps provide your home with extra protection. If the sensor is connected to a full system, you’ll receive instant mobile alerts of glass breaking even when you’re away and professional monitoring services can notify emergency responders on your behalf. If the glass break sensor is standalone, you may not receive instant alerts and if the sensor’s alarm sounds, you won’t know if you’re away.
  • Wireless vs. hardwired glass break sensors  – Glass break sensors can be wired through your home’s electricity or battery-operated wire-free. Wireless sensors have a peel-and-stick adhesive or one screw for easy installation. Wireless sensors are popular rental properties or dorms. They often only detect breaking glass and sound a high-decibel alarm to alert you. If you’re looking for a more durable glass break sensor that connects to a monitored system, sends mobile push notifications or has a tamper-resistant design, you’ll want to consider a hardwired glass break sensor. These can be professionally installed and are most suitable for home and business owners.
Benefits of Glass Break Sensors

Benefits of Glass Break Sensors

  • Deters potential burglars

    Burglars often force entry by breaking door glass and windows. If thieves are trying to break in and hear the glass break sensor’s loud alarm, they’ll think twice before entering because they know your home is protected.

  • Wider covered range

    With one glass break sensor, you’ll know a wide range of your home is protected since the 360-degree design allows the sensor to listen for glass breaking from all angles. The best part is, you’ll need a lot fewer glass break sensors to cover a wider range in your home instead of window sensors which only cover 1-2 windows.

  • Added home security

    You’ll never have to wonder if you heard glass break because your sensor will automatically alert you. You should expect a mobile notification or loud alarm if the glass break sensor’s microphone hears the unique sound of glass breaking or shattering.

Installing glass break sensors is one easy and affordable way to help protect your home. Remember to check for all of the glass break sensor’s features you’ll need to feel safe.

Glass Break Sensor FAQs

Glass Break Sensor FAQs

How do glass break sensors work?

Glass break sensors use a microphone to listen and detect the sound of glass breaking.. Some glass break sensors use additional technology to distinguish between the initial sound of glass cracking and the shattering of glass. Glass break sensor also work differently depending on the type of glass.

What’s the difference between a glass break sensor and a window sensor?

Window sensors are designed to alert you when a window is opened, however, they don’t alert you if the window is shattered. Glass break sensors are designed to let you know if your home’s glass is cracked or broken. Also, keep in mind that window sensors cover one area while one glass break sensor covers an area within a certain range.

Where should I install a glass break sensor?

If you own a fully monitored home security system, your provider’s installation technician will install the glass break sensor for you. If you’re installing DIY security equipment, there are a few common places glass break sensors should be placed such as your home’s wall six feet high or ceiling free from anything blocking it. Before installing, read over the manufacturer’s manual for proper installation tips. You’ll want to mount the sensor within the manufacturer’s suggested range to detect broken glass in the sensor’s range.
