Are there false alarms with glass break detectors?

Look for Dual Technology in Glass Break Detectors

Look for glass break detectors that "hear" both high and low frequency sounds. Otherwise, you may get a lot of false alarms.

The dual technology listens for an object hitting and flexing the glass, followed by the high sound of breaking glass. When it "hears" the two sounds, in that order, the alarm activates.

Sometimes alarm companies use single technology because it is cheaper. But a single technology alarm sometimes mistakes other noises for breaking glass, like music playing, lightning strikes, even someone sneezing.

Dual technology ends those problems and allows for a much more sensitive device.
