Ajax MotionProtect Jeweller
Summary
The Ajax MotionProtect Jeweller is a sophisticated wireless indoor IR motion detector designed to deliver exceptional security performance with advanced false alarm prevention. Featuring a detection range of up to 12 metres with 88.5° horizontal and 80° vertical viewing angles, this detector provides comprehensive coverage for indoor security applications whilst intelligently filtering out common sources of false alarms.
Engineered with cutting-edge SmartDetect algorithm and special optics, the MotionProtect Jeweller combines hardware and software innovations to distinguish between genuine security threats and false triggers such as pets, temperature fluctuations, and environmental interference. The detector offers pet immunity for animals up to 20kg in weight and 50cm in height, making it ideal for homes and businesses with pets.
Built for professional installation and long-term reliability, the MotionProtect Jeweller operates for up to 5 years on a single pre-installed CR123A battery and communicates via the secure Jeweller protocol with up to 1,700m range. The effortless installation system with SmartBracket mounting and QR code pairing ensures quick deployment, whilst temperature compensation and three adjustable sensitivity levels provide optimal performance in diverse environments.

FAQ
How does the false alarm prevention system work?
The MotionProtect Jeweller uses a combination of special optics and the SmartDetect algorithm. The detector lens increases sensitivity to human motion whilst filtering out IR radiation from pets and other interferences. The SmartDetect algorithm continuously analyses thermal patterns, movement size, speed, and other parameters to distinguish between genuine threats and false triggers.
What pets can the detector ignore and how is this achieved?
The detector provides pet immunity for animals up to 20kg in weight and 50cm in height. This is achieved through the special optical design where small lens sections are affected by pet movement, whilst larger sections focus on areas most likely to detect human intruders. When properly installed at 2.4m height, the system reliably ignores common household pets.
How long does the battery last and can it be replaced?
The MotionProtect Jeweller operates for up to 5 years on a single pre-installed CR123A battery. The battery is user-replaceable, and the system provides low battery notifications well in advance through the Ajax app, ensuring uninterrupted security coverage.
What is the detection range and coverage area?
The detector provides up to 12m detection distance when installed at the recommended height of 2.4m. It offers 88.5° horizontal and 80° vertical viewing angles, creating comprehensive coverage for rooms and corridors. The detection works optimally for motion speeds between 0.3 to 2.0 m/s.
Can the sensitivity be adjusted for different environments?
Yes, the MotionProtect Jeweller offers three adjustable sensitivity levels that can be configured remotely via the Ajax app. This allows fine-tuning for different environments, room sizes, and specific security requirements, whilst the temperature compensation ensures consistent performance across varying conditions.
How does the wireless communication work and what is the range?
The detector uses Ajax’s proprietary Jeweller communication technology with encryption and device authentication. It provides up to 1,700m communication range in open space with polling intervals from 12-300 seconds. The system includes anti-jamming protection and real-time status monitoring.
Is professional installation required?
While the MotionProtect Jeweller features effortless installation with the SmartBracket mounting system and QR code pairing, professional installation is recommended to ensure optimal placement, coverage, and integration with the security system for maximum effectiveness and minimal false alarms.
