The Ajax GlassProtect is a wireless acoustic detector designed to identify the sound of breaking glass and alert you to a potential intrusion. It uses an electret microphone and a specialized DualTone digital algorithm that analyzes both low and high-frequency sounds to distinguish the specific noise of shattering glass from other household sounds. This ensures that the system only triggers when a real threat is present, covering an area with a 180° detection angle and a range of up to 9 meters. This compact white device measures 90 x 20 mm and weighs only 30 g, allowing it to blend discreetly into your interior when mounted on a wall or ceiling. It communicates with your hub via the secure Jeweller radio protocol, which provides a reliable connection over distances up to 2000 meters in open spaces. You can adjust the sensitivity across three different levels to suit your specific environment, and the integrated tamper button protects the unit from unauthorized removal. Powered by a single CR123A battery, the detector can operate for up to 7 years without needing a replacement. It also includes a built-in temperature sensor that functions within a range of -10°C to +40°C. The package comes with everything needed for a quick setup, including the SmartBracket mounting plate and a distance terminal, making it a practical choice for anyone looking to secure large windows or glass doors.
