Ajax Superior MotionProtect G3 Black — Grade 3 Wireless Motion Detector with Anti-Masking

Professional Grade 3 High-Security Wireless PIR Motion Detector Ajax Superior MotionProtect G3 Jeweller Black

The Ajax Superior MotionProtect G3 Jeweller in black marks a significant technological milestone in electronic security, serving as the world's first fully wireless passive infrared (PIR) motion detector to achieve the prestigious high-security EN 50131 Grade 3 and PD 6662:2017 certification. This top-tier classification makes it the required choice for protecting critical infrastructure and high-risk commercial premises, such as banking institutions, jewelry stores, museums, government buildings, high-value warehouses, and military facilities.

Unlike standard motion sensors, MotionProtect G3 utilizes an advanced optical system built around a high-precision multifaceted focusing mirror combined with a latest-generation volumetric PIR sensor. This optics design enables accurate detection of slow, fast, or crawling human movement up to 15 meters away while maintaining a wide 90° horizontal and 71° vertical field of view. Furthermore, the mirror optical path reduces the lower blind spot to just 30 cm, preventing intruders from crawling beneath the detector along the wall unnoticed.

#### Active Anti-Masking System & Triple Tamper Protection

To comply with rigorous Grade 3 standards, the device features an active anti-masking system that operates continuously, even when the security system is disarmed. Utilizing dedicated infrared sensors, the detector instantly identifies sabotage attempts involving spray paint, adhesive tape, transparent lacquer, or physical barriers placed in front of the lens, triggering an alert in less than 120 seconds. Physical security is fortified by a triple tamper switch that monitors casing opening, wall detachment, and bracket removal.

#### Professional Radio Protocols & Exceptional Battery Life

Communication with the hub is powered by the Superior Jeweller high-security radio protocol, featuring dynamic key encryption, frequency hopping, and automatic jamming detection to reach up to 3,000 meters in open terrain. The secondary Wings protocol manages fast over-the-air (OTA) firmware updates. The unit comes equipped with the SmartBracket mounting panel featuring a built-in bubble level, holding locking screw, and 4 pre-installed CR123A batteries delivering up to 7 years of continuous operation.
