Secure your perimeter with unmatched precision using the Ajax Curtain Outdoor Jeweller (101441.289.WH1) – a professional wireless curtain motion detector ideal for outdoor and indoor perimeter protection. This advanced sensor creates a narrow detection "curtain" up to 12 meters long, perfectly safeguarding windows, doors, gates, archways, and facades while ignoring animals, swaying plants, or thermal interference.

Powered by dual PIR sensors and a K-band microwave for dual-technology verification, it virtually eliminates false alarms with proprietary ELSA algorithms and temperature compensation. Features include pet immunity (configurable via slider), active anti-masking system, multi-level tamper protection with accelerometer, and adjustable sensitivity/range directly on the device or via Ajax app.

Rated IP55 for full weather resistance (dust, water jets, UV), it operates reliably from -25°C to +60°C. Easy installation with SmartBracket, optional angle mount or hood for rain/snow protection, and encrypted Jeweller radio protocol for up to 1,700m range.

Pre-installed batteries provide up to 3 years of autonomous operation. Fully compatible with Ajax Hub 2, Hub 2 Plus, and Hub Hybrid – elevate your security system with reliable, intelligent perimeter defense.
