Glass break sensors are audio sensors that trigger an alarm when they detect the sound of glass being shattered. Glass break sensors work by listening for sound patterns and frequencies of breaking glass, and multiple sensors should be installed to cover the target window area. They are especially popular among businesses that showcase high-value merchandise in a window display such as jewelry stores, luxury retailers and art galleries, which tend to attract “smash and grab” style break-ins. For these types of businesses, their business insurance provider would likely require glass break sensors as part of their comprehensive business security system.
