Glass Break Sensor

Say a burglar has managed to get into your house. He has stolen your TV, laptop, cell phones and even that jewelry you thought you had hidden so well. Late at night, you walk in to your living room only to find everything scattered around, and your valuable items missing. Your heart sinks as you come to terms with the realization that you got robbed.  

So now what?

You may be able replace all the items, provided your insurance company comes through. But can you replace the peace of mind that you lost?

This may sound unlikely, but yes, you can.

It happened to you once; you can make sure it never happens again. How? By defending all potential points of intrusion.

Protection-What you might be overlooking

While people are busy installing sophisticated locks and alarms for their doors and windows, garages, driveways and safes, they tend to ignore the possibility of someone literally ‘breaking’ in. A burglar can easily break the window with one strong punch and disable whatever alarm you installed by wiggling his hand in. Once the window alarm is disabled, it’s a piece of cake for him. What you need here is a glass break sensor.

What are they?

These sensors are designed to detect the unique sound frequency of breaking glass. There are two types of glass break sensors: Shock sensors and acoustic sensors.

Shock Sensors are designed to detect vibrations produced by breaking glass and trigger the alarm accordingly. They are usually mounted on a specific window. When glass breaks, the vibration of the window sends an alert to the sensor, which in turn activates the device.

Acoustic sensors are designed to be triggered by sound waves. They are generally installed in the corner of a room or on the ceiling and can cover windows within a distance of 30 to 40 feet in all directions. These sensors are not designed to detect triggers through walls or around corners. They are best utilized in rooms with many windows. They are designed to specially detect breaking of glass or splintering of wood. They protect a wider area than shock sensors, but might be mistakenly activated by noises that sound like breaking glass.

How to make sure you are sufficiently covered?

The placement of these sensors is a matter you will need to put a lot of thought into. Among the home security devices, glass break sensors are relatively more expensive. So you want to make sure you buy just the required number of sensors and utilize them in the best, most comprehensive manner.

  • If you have an open kitchen, breakfast corner and a family living room, you can cover all these areas with one device, assuming they will fall within a 35 ft radius

  • If you have a main room, living room with a lot of windows, you can cover them all with one sensor. The greater the number of windows in a room, the more fully utilized your sensor is

  • If you have a basement with windows, it is a very vulnerable area; away from the main house and away from your eyes for the most part. One sensor in the basement may be enough to defend you against any intrusions.

To make sure you come up with a cost effective plan, it would be advisable to sit with a professional and plan out your exact security needs.

A few parting statistics!

If all of the above has not managed to convince you about the importance of defending one of the two main entry points, then you need to take a look at the following: (All figures from BJS)

  • Whether the residence is occupied or not, removing or damaging a window screen during a forcible entry is almost equally likely to occur. (11% for occupied, 9% for unoccupied)

  • 48.8% of the burglaries took place through windows and this involved forcible entry. This statistic is when a household member was in the house.

  • Out of the above 48.8%, 30% were attributed to a pane damaged or removed

  • When household members were present, window forcible entry was used 47% of the time, out of which 27.6% was by damaging or removing the window pane

So instead of becoming one of these numbers, get yourself a set of glass break sensors. Even with a sophisticated home security system, all the burglar needs is one weak point. Don’t give it to him.
