Room-Wide Coverage
A single sensor can cover multiple windows within line of sight, so you don't need one per window.
Callaway Security & Sound installs glass break detectors that listen for the exact sound of breaking glass, closing a gap that door and window sensors alone can miss. One sensor can cover an entire room of windows from a single mounting point.
A door sensor only knows if a door opens. It won't catch someone who skips the door entirely and smashes a window instead. Callaway Security & Sound installs Alarm.com powered glass break detectors that listen for the exact sound of shattering glass and trigger an alert immediately, closing a gap that door and window contacts alone can miss.
Older glass break sensors were notorious for going off over everyday noise. Today's detectors are far more precise, requiring two specific sounds in sequence before they ever trigger an alarm.
The sensor first listens for the low-pitched "thud" of an object striking the glass.
It then confirms the high-pitched frequency that only happens when glass actually breaks.
Only when both sounds are confirmed does the sensor trigger, keeping false alarms rare.
We'll help you decide where glass break coverage makes sense during your walkthrough.
A single sensor can cover multiple windows within line of sight, so you don't need one per window.
Requires both the impact sound and the glass frequency, so dropped dishes or clapping won't set it off.
Wireless models communicate over an encrypted connection to the panel, keeping the signal secure.
A good option for rooms where a motion sensor isn't practical because of a large dog or cat in the house.
Available as a hardwired or wireless sensor, so it fits new construction and retrofits alike.
Popular with retailers and jewelers to monitor display cases and storefront glass, not just windows.
Here's the gap a glass break detector closes that a window contact can't cover by itself.
| Scenario | Window Sensor Only | Window Sensor + Glass Break |
|---|---|---|
| Window Is Opened | Alarm triggers | Alarm triggers |
| Glass Is Shattered | May not trigger | Alarm triggers on the sound of breakage |
| Multiple Windows in One Room | A sensor needed on each one | One detector can cover the whole room |
| Sliding Glass Doors | Limited coverage | Added protection against a smashed panel |
Glass break detectors are designed to work alongside door and window sensors, not replace them. Together they cover both how a window is opened and how it can be broken into.
Anywhere glass is the easiest way in, or the thing worth protecting.
Answers to what customers ask us most about glass break detectors.
Window sensors only trigger if the window is opened. A glass break detector catches someone who shatters the glass instead of opening it, which is a common way windows are bypassed during a break-in.
It shouldn't. Modern detectors are built to confirm two specific sounds, the impact and the actual glass frequency, before triggering, which filters out things like dropped dishes or a loud clap.
A single sensor can typically cover a room with several windows, as long as they're within line of sight and roughly 25 feet of the sensor. We'll confirm placement during your walkthrough.
In some cases, yes. Homes with large dogs or cats sometimes use glass break detectors in place of motion sensors to avoid false alarms triggered by pet movement.
No. These sensors listen for airborne sound, so they're designed to cover the room they're installed in, not adjacent rooms behind closed doors or walls.
No. They're also popular for retail storefronts, jewelers, and offices with glass partitions or display cases, anywhere breakable glass is a way in or something worth protecting.
We'll walk your property, point out the windows and doors most at risk, and give you a clear quote before anything is installed.
