Protection against any threat
Baseline product line comprises wireless devices to protect residential and commercial properties. A wide range of smart indoor and outdoor Ajax devices operate as a unified force to ensure protection against potential intrusion and deliver the best-in-class user experience.

Intruders can break silence, not security
Forget about false alarms from barking dogs, traffic, water, and noise with glass break detectors. GlassProtect Jeweller uses a DualTone digital algorithm to reduce false alarms. Its microphone detects only vibrations from breaking glass. You can adjust one of three sensitivity levels and run a test to ensure it works well.
Enhanced glass break detection
GlassProtect Jeweller uses a sensitive electret microphone and the DualTone digital algorithm to detect glass breaking sounds. It detects low-frequency impact sounds and high-frequency breaking sounds within 1. 5 seconds to register an alarm. This two-stage detection reduces false alarms. The Ajax app allows three sensitivity levels to be set, making it suitable for various objects.

Overview:
GlassProtect is a wireless indoor glass break detector that can detect the sound of shattering glass from up to 9 meters away. It has a battery life of up to 7 years and connects to the Ajax system through the Jeweller radio protocol, with a range of 1,000 meters in line of sight.
Users can configure it via the Ajax app on macOS, Windows, iOS, or Android, receiving notifications through push alerts, SMS, and calls if activated. The Ajax system can also connect to a security company's central monitoring station.
