The Ajax MotionProtect Curtain is a wireless motion detector designed to protect large glass surfaces, such as windows or balconies, by creating a narrow detection zone. It utilizes two PIR sensors with a multifaceted mirror to monitor a vertical area, with a detection distance that you can adjust between 6 and 15 meters. To ensure accuracy, the device features three sensitivity levels and Correlation Signal Processing, which helps reduce the likelihood of false alarms. This white detector is built for indoor use and is best installed at a height of 2.4 meters. Its compact 134 × 44 × 34 mm frame is protected by an IP54 rating, making it resilient to dust and moisture. It communicates with Ajax hubs and range extenders via the Jeweller radio protocol, maintaining a stable connection over distances up to 1700 meters in open areas. Integrated sensors allow the device to monitor the ambient temperature, while a simple LED indicator provides visual status updates. Powered by a single CR123A battery, the unit can operate for up to 3 years without a replacement. When movement is detected, the system delivers an alarm signal in just 0.15 seconds, providing a rapid response for your home or office security.
