If your home is similar to many other wired homes, you will have plenty of glass windows for ventilation and/or for letting the outside world into your home. With so much glass a home like this can have its own security issues. Enter the professional-grade security device that just listens for glass breaking.

This device made by HAI, listens for glass breaking. You already have windows and doors covered by a security system that detects when a door or a window is opened. But what about if a glass window is broken, the security strips do not work. Enter the HAI device which detects glass breaking.

From a radius of 20 feet this device is sensitive to the sound of a glass window 1ft or 2ft square or larger being broken. Installation is simple but it does need communication through a wireless/wifi system to the network.

Priced at just US$109 it is a very worthwhile investment to further improve the security of your home.
