Glass Break Break-Ins

Posted by , , at 2:23 pm

This summer, burglars broke into numerous homes in North Texas using a simple method: breaking the glass backdoor. And this can occur anywhere, not just North Texas. “Criminals know it’s one of the weakest spots in the home,” said Steve Barron of Designer Door & Window, based in Plano, Texas.

The home’s rear entrance has always been a favorite for burglars with 22 percent of all intruders gaining entry to residential homes through the backdoor. But these North Texas thieves aren’t simply jiggling with the locks or opening an unlocked door, they’re actually breaking the glass. And after breaking the glass, they often simply walk through the opening they’ve created.

Based on the article, it appears that these homes either didn’t have effective alarm systems to begin with, or were relying solely on Door and Windows Sensors. And since doors weren’t actually being opened, the alarms weren’t triggered to send an alert.

A Need for a Variety

Burglars are always trying to find easier methods to break into homes. In most cases, relying on a couple of Door and Window Sensors – and no other sensors – won’t get the job done anymore. “Whenever there is a specific type of criminal activity that seems to be successful, I think other people will use a similar technique,” says David Tilley, Plano police spokesman.

Luckily, there’s plenty of sensor variety to choose from. Besides the opening of doors and windows, there are sensors designed to sense motion and even the movement of a garage door.

There’s also a sensor specifically designed to detect the sound of breaking glass. Glass Break Sensors have a large range, so they don’t need to be placed on a specific window. Instead, any windows within a 20 feet radius will be covered.

It’s more important than ever to have variety of security sensors with your system. Burglars are constantly trying to get the jump on you, so stay a step ahead of them by making sure your house is protected against all types of intrusion.

    442-251-2029 I’m interested in glass breaking sensors and motion sensor please call with furthur information and quotes. Thank you

    You say a glass break sensor is effective up to 20 feet. My townhouse back yard patio area has 2 sliding arcadia doors with a concrete block wall between the two @ 10-15 feet long 7-9 feet tall. Would I require 2 separate sensors or one? Plus, my next question is where would be the best place to install a single glass break sensor as opposed to 2 separate sensors? I also have roll down window protection on both back patio arcadia door windows help keep the cost of electricity down.

      Hi Charles, great question! This highly depends on your home’s layout. Does the concrete wall completely block off the two doors from each other? In this case, it’d be best to go with two sensors.

      However, if you place a single Glass Break Sensor on the opposite wall so it faces the two sliding doors, and where it has a line of sight of both doors, a single sensor may work.

    Now, you’ve puzzled me. I thought the glass break sensors only triggered an alarm if the system was armed. Why would it be any other way? If the system is disarmed, isn’t the intent not to have any sensor trigger an alarm?

    Please give me more information like price and install info thanks

      Hi Rhoda, did you mean just the Glass Break Sensor? Or were you interested in a full system?

    We’ve had a rash of burglaries recently here in the Bay Area (California). I’ve seen number of photos of these sliding glass door break-ins posted on our neighborhood Nextdoor website. This seems to be the favorite entry technique. Most of the homes either had improperly placed motion sensors, no glass breakage sensors, or no alarm system at all.

    Question: do curtains or indoor window shades block the sound of breaking glass?

    • Gilbert Cho

      Hi George, curtains/shades will not stop the Glass Break Sensor from detecting the sound of breaking glass, unless it’s too far away. We recommend setting up your Glass Break Sensor no more than 20 feet away from the windows you want to protect.

    Does the glass break sensor arm itself when the “Doors and Windows” feature is armed or only when the “Motions” sensor is armed, or both?

    • Gilbert Cho

      Hi JK, the Glass Break Sensor will be armed by both!

    Which is more effective… A glass break sensor or a motion detector covering the area of a glass door?

    • Marc Miller

      Motion detectors are probably a better buy because they cover things beyond just glass, but if you have large pets or if there is often safe activity happening outside the glass, the motion detector may give too many false alarms. Also motion detectors won’t be effective if disabled (such as when you arm your system at night, disabling motion detectors). Glass sensors on the FrontPoint system stay active all the time, meaning you’ll be alerted immediately of someone breaking in through a back door while the system is disarmed.

      Glass sensors also have caveats — they’re not recommended for areas like kitchens where glass or ceramic plates often clink together because glass sensors work off of the *sound* of glass, and they stay active even while the rest of the system is disarmed. If you or your kids accidentally drop a glass, you have both a mess and a burglar alarm to deal with.

      Of course, you can call FrontPoint to have them ignore the glass sensor signal if you are having windows replaced, or purposely breaking down glass nearby.

    Could you share a link or links or recommended sensors? Thanks.

  9. J Wied

    That’s an excellent idea Dan; I agree that would be an extra deterrent.

  10. Dan Switzler

    Would like to see Frontpoint add “Glass Break Sensor” window sticker option for those of us that have them. This would allow a static sticker to be placed on our large [ i.e. sliding doors ] glass windows to further deter would be burglars, assuming they can read.




      Yes! Please do this! That would be a huge help for us.
