Break Glass Detectors

Break glass detectors are designed to detect glass break activity and trigger a compatible alarm system. Depending on the model, they may detect the sound frequency of breaking glass, vibration through a surface, or both.

Break glass sensors help protect vulnerable glass areas that may not be fully covered by standard motion detectors or reed switches alone. They can trigger an alarm when glass break activity is detected, helping alert you earlier to a possible intrusion.

• Detects the sound or vibration of breaking glass
• Helps protect windows, glass doors and shopfronts
• Provides early warning of forced-entry attempts
• Suitable for homes, offices and retail stores
• Can be used with compatible wired or wireless alarm systems
• Useful for rooms with large glass panels or multiple windows
• Adds protection where intruders may avoid opening a door or window
• Supports layered alarm system design

Glass break detectors are commonly used in areas where glass is a likely target for forced entry. They can be especially useful in properties with large windows, sliding doors, display areas or external glass panels.

• Front windows and rear windows
• Glass sliding doors
• Retail shopfronts
• Office glass entry points
• Showrooms and display areas
• Homes with large glass doors or windows
• Commercial reception areas
• Ground-floor offices and exposed glass areas

Shop break glass sensors and glass break detectors from trusted alarm and security brands. Compatibility will depend on your alarm panel, receiver and system type.

The right break glass detector depends on the alarm system brand, room layout, glass type, distance from the glass, wiring requirements and whether you need wired or wireless detection. Correct placement is important for reliable performance.

Where should break glass sensors be installed?
They are commonly used near windows, glass sliding doors, retail shopfronts, display areas and other vulnerable glass entry points.

Are break glass detectors wired or wireless?
Break glass detectors are available in wired and wireless options, depending on the brand and compatible alarm system.

Do I still need reed switches if I have break glass sensors?
Break glass sensors and reed switches do different jobs. Reed switches detect opening doors or windows, while break glass sensors help detect smashed glass. Many systems use both for layered protection.
