Ajax Superior MotionProtect Plus G3 White — Grade 3 Dual-Tech Motion Detector (PIR + Microwave)

Grade 3 Professional Wireless Dual-Technology Motion Detector Ajax Superior MotionProtect Plus G3 Jeweller White

The Ajax Superior MotionProtect Plus G3 Jeweller in white is the world's first fully wireless dual-technology motion detector certified to strict high-security EN 50131 Grade 3 and PD 6662:2017 standards. Engineered for high-risk commercial, industrial, and institutional premises — such as banks, jewelry stores, museums, server rooms, vault rooms, and defense facilities —, it delivers total immunity to false alarms in spaces with harsh thermal interference.

The key innovation of the Plus model is its combination of a passive infrared (PIR) thermal sensor with a K-band microwave sensor (24 GHz). When the PIR sensor detects a thermal variation, the microwave sensor performs an active Doppler check to verify physical mass movement. This process effectively filters out false alarms caused by HVAC systems, air drafts, fireplaces, heaters, or direct solar glare.

Its optical system relies on a high-precision multifaceted mirror delivering volumetric coverage up to 15 meters with 90° horizontal and 71° vertical field of view. An ultra-short lower blind spot of only 30 cm prevents intruders from crawling unnoticed beneath the device along the wall.

#### Active Anti-Masking & Advanced Sabotage Protection

To meet Grade 3 mandates, MotionProtect Plus G3 Jeweller incorporates an active anti-masking infrared system. It immediately detects attempts to blind the lens using spray paint, lacquer, tape, or physical covers, issuing an alarm within 120 seconds (even when disarmed). Physical security is fortified by triple tamper switches (enclosure opening, wall removal, and SmartBracket panel detachment with holding screw lock).

#### Professional Radio & Quick Installation

Operating via two-way proprietary Superior Jeweller (alarms with frequency hopping and range up to 3,500m) and Wings (OTA updates) protocols, the detector ensures block encryption and jamming protection. It comes with a SmartBracket mounting panel with a built-in bubble level and 4 pre-installed CR123A batteries providing up to 5 years of battery life.
