    From what I understand is that it senses a certain sound frequency that glass breaks at. With that said there are other sounds that are similar within that range and would set it off. For example I set it off by coming in the back door and throwing something on the table which bounced a center piece with rocks on it while I was on the way to turn the alarm off. I was puzzled for a moment about why the alarm sounded before I disarmed, but then realized what I did. My friend set it off once by her high pitch sneeze, but she was within 5ft of the sensor. I think it's a great product, I also tried setting it off to see if it works 30ft away by breaking glass in a trash can, and that worked.

    I'm giving it 3 stars because it has falsed a couple times on me...I have not tried actually breaking glass. But the unit is located in my living room and my surround sound system can set it off with big band music...which will normally just make it chime so not a huge deal...another time my cat knocked the laptop over and no glass was broken but this set my alarm off at night. Because of this I'm pretty sure an actual window breaking will set it off..but be careful about false alarms. on the bright side I've heard barking can set it off..and this glass break seems to completely ignore barks from my 80lb puppy.
