How Do Glass Break Sensors Work?

Posted: May 06, 2019

Glass break sensors are a must-have home security component, but do you know how it works? When a pane of glass shatters, they give off a very distinct frequency. That frequency is "heard" by the glass break sensor and triggers your alarm to send help.

You may be thinking to yourself, that sounds great, but do I need one? Here's why a glass break sensor can help keep your family and home safe.
