## Summary description

The Ajax GlassProtect is a wireless door/window sensor designed for security. It operates at a frequency of 868 MHz and uses a CR123A battery with a lifespan of up to 84 months. Compact dimensions of 20x20x90 mm make it easy to install in various locations. Ideal for protecting your home or office from unauthorized access.

## Long description

The Ajax GlassProtect Wireless detector notifies the system when glass is broken by intruders. Compact and battery-powered, the device is intended for mounting near windows and covers detection at distances up to 9 m while filtering out common false triggers.
Advantages
The detector uses an electret microphone to register both the impact on the glass and the sound of falling glass, enabling reliable detection of breakage. A two-factor detection algorithm reduces false alarms caused by thunder, barking dogs or traffic noise. The unit comes with a preinstalled CR123A battery and pairs with the Ajax hub via the mobile app with a single click, allowing quick installation and immediate operation.
Suitable for
Protecting home windows and balcony doors
Securing office glass partitions and storefront windows
Use in apartments, houses and commercial premises where wireless detection is required
