Our Top Glass Break Alarms Sensors

1. EVA LOGIK Glass Break Sensor

EVA LOGIK Glass Break Sensor

Alarms are really loud and the flashing LED is a great touch to give any thieves a second guess...

Our Rating:
4.5/5

The EVA LOGIK glass break sensor is a vibration-based alarm that picks up the shock vibrations caused by a shattering window.

It has high and low sensitivity settings as well, indicated by a plus and minus symbol, respectively.

The alarm is super easy to install, as it sticks right onto the windowpane via adhesive. It also comes with a double-sided warning sticker that shows through the glass when you place it on the window.

The alarm runs on two AAA batteries – not included – which last a lot longer than traditional button batteries (about two years, to be exact).

An LED on the sensor blinks every four seconds to deter possible intruders even in the dark and stays solid red when the battery life is low, indicating that you need to replace the batteries.

The alarm itself is also incredibly loud, sounding off for a continuous 60 seconds at 120 decibels, so you’re guaranteed to hear it when it goes off.

2. Doberman Security

I bought these alarms last year and last night they saved my house from a full robbery...

Our Rating:
4.1/5

The Doberman alarm is another vibration type sensor that comes with a strong adhesive backing to install the device right onto the windowpane.

The sensor is slim, and you can reposition it if you work it off the window with a thin object such as a knife. The Doberman alarm runs on button batteries, which do come included.

There is no LED indicator to alert you of low battery life, but there is an on and off switch which allows you to save battery life if you know you won’t need to use the sensor.

The Doberman sensor doesn’t come with any sensitivity settings, but it is relatively well-tuned to cut down on false alarms. A strong pounding on the window will set it off, but otherwise, it’ll take an actual break-in to get it going.

Strong winds and heavy rain won’t set it off, though hail might if the hailstones are large enough or frequent enough. When something triggers the alarm, the Doberman sounds off for 30 seconds at 100 decibels and then automatically shuts off.

3. Honeywell Intellisense Acoustic Sensor

If you are looking for a hardwired glass break this unit works great....

Our Rating:
4.3/5

The Honeywell Acoustic Sensor is a sound-based system that covers a wide range of 25 feet.

It picks up the frequencies for any glass type and has adjustable sensitivity via the two switches within the sensor.

It’s a hardwired unit, which means you’ll need to mount the alarm and connect the wires, but it only takes about 15 minutes to do the job, and you won’t need to worry about frequently replacing batteries.

4. Toeeson 120DB Alarm for Doors and Windows

door break alarm

I got them as I have toddlers and want to know if they open a door or window....

Our Rating:
4.5/5

The Toesson alarm is a unique type of sensor because it uses magnets.

Each sensor (as you get multiple when you order them) comes with a magnet that sits right next to each sensor.

These alarms come with a strong adhesive backing that allows you to place them on doors as well.

The on and off switch allows you to turn them off when you need to open the windows and doors then on during the night, so if an intruder manages to open either, you’ll know.

The sensor runs on three LR44 button batteries with an LED indicator to alert you when battery life is low. The sensor must be within a centimeter of the magnet for things to work correctly and comes with helpful arrows to show you how to line things up.
 
The alarm sounds off at 120 decibels, so you’re guaranteed to wake up when it goes off.

5. Honeywell 5853 Wireless Glass Break Detector

honeywell 5853

Extremely sensitive out of the box. It takes a bit of trial and error to dial in the sensitivity settings....

Our Rating:
4.5/5

For our last recommendation, we have another Honeywell product, though this one is a wireless unit.

It’s a sound-based sensor that runs on long-lasting batteries (you can get about ten years out of it), and you must mount it onto the wall. The range is about 25 feet and detects the sound of multiple types of glass, such as tampered, laminate, wired, and ordinary plate glass.

This alarm has four different sensitivity settings: Max, medium, low, and lowest. It takes a little trial and error to get the sensitivity settings just right, but once you do, you ensure you have a unit that functions incredibly well.

If you purchase an FG-701 tester, you can also activate a test mode for this unit.

This Honeywell product is compatible with other wireless devices of the 5800 series.

Unfortunately, however, ADT – a prominent security system manufacturer – might not let you install these devices in your home.

The Best Alarm Overall

While every sensor on this list is a strong competitor for the best for different reasons, the sensor we’d recommend the most would be the EVA LOGIK Window Alarm.

The EVA LOGIK is easy to install, has a long battery life, and has adjustable sensitivity. The sensor comes wireless and ready to stick right onto your windowpane and possesses that warning blinking LED that the others do not.

If the LED and the warning sticker aren’t enough to deter the intruder, the high volume of the alarm once the window is shattered or pounded on certainly will.

While we’d recommend the EVA LOGIK to anyone looking to buy their first alarm that’s guaranteed to do the job, check out the others on the list, especially if you think you want something sound-based or, like Toeeson, magnet-based.

Do invest in at least one of them, however, because a window break alarm is a security measure that every home can benefit from.
