The Ajax MotionProtect Curtain is a wireless curtain-type motion detector designed for indoor perimeter security, ideal for protecting windows, doors, and other entry points.
 
It features a narrow horizontal detection angle (6°) and a vertical angle of 90°, with a motion detection range of 6 to 15 meters, adjustable based on sensitivity settings.
 
Equipped with two PIR sensors and a multifaceted mirror optical system, it provides precise detection of human movement, including slow or fast motion, while minimizing false alarms through Correlation Signal Processing.
 
The detector is pet-immune when installed correctly, ignoring animals like large dogs (e.g., Saint Bernards) if mounted upside-down at 40 cm above the ground.It connects to Ajax hubs (Hub, Hub Plus, Hub 2, ReX) via the secure Jeweller protocol, offering a communication range of up to 1,700 meters in open spaces.
 
The device uses advanced encryption and switches frequencies in case of interference or jamming, ensuring reliable data transmission. Powered by a pre-installed CR123A battery, it operates for up to 3 years and is configured via the Ajax mobile app (iOS/Android) by scanning a QR code.
 
The MotionProtect Curtain is IP54-rated, operates in temperatures from -10°C to +40°C, and is suitable for homes, garages, or museums. It supports easy installation with a SmartBracket mount and includes anti-tampering features.
