Ajax MotionProtect Plus Jeweller
Summary
The Ajax MotionProtect Plus Jeweller represents the pinnacle of wireless motion detection technology, featuring dual-sensor architecture with both PIR and K-band microwave sensors. This advanced motion detector provides up to 12 metres detection distance with 88.5° horizontal viewing angle, whilst the innovative dual-technology approach virtually eliminates false alarms by requiring verification from both sensors before triggering an alarm.
Engineered for maximum reliability, the MotionProtect Plus combines the proven SmartDetect algorithm with dual-sensor verification, where the microwave sensor confirms PIR sensor alarms before activation. This sophisticated approach, combined with temperature compensation and three adjustable sensitivity levels, ensures exceptional performance across diverse environments whilst maintaining pet immunity for animals up to 20kg weight and 50cm height.
Designed for professional security installations requiring the highest levels of reliability, the MotionProtect Plus operates for up to 5 years on pre-installed batteries and communicates via the secure Jeweller protocol with up to 1,200m range. The effortless installation system with SmartBracket mounting, QR code pairing, and battery replacement without opening the enclosure ensures minimal maintenance and maximum uptime for critical security applications.

FAQ
How does the dual-sensor technology work and why is it better?
The MotionProtect Plus features both PIR (infrared) and K-band microwave sensors working together. The PIR sensor detects thermal changes whilst the microwave sensor detects movement. An alarm is only triggered when both sensors detect motion simultaneously, virtually eliminating false alarms from sources like temperature changes, small animals, or environmental factors that might trigger a single sensor.
What is the difference between MotionProtect and MotionProtect Plus?
The Plus version adds a K-band microwave sensor to the standard PIR sensor, providing dual-technology verification that significantly reduces false alarms. This makes the Plus ideal for environments where false alarm prevention is critical, such as areas with pets, temperature fluctuations, or other potential interference sources.
How does the pet immunity work with dual sensors?
The dual-sensor design enhances pet immunity beyond the standard model. The PIR sensor uses special optics to minimise pet detection, whilst the microwave sensor can be configured to ignore the movement patterns typical of pets up to 20kg and 50cm height. Both sensors must confirm human-sized movement for an alarm to trigger.
What is the detection range and optimal installation height?
The detector provides up to 12m detection distance when installed at the recommended height of 2.4m. The 88.5° horizontal viewing angle ensures comprehensive room coverage, and the detector should be positioned so the lens is perpendicular to the expected intrusion path for optimal performance.
How long does installation and setup take?
Installation is designed to be effortless with the SmartBracket mounting system requiring no enclosure disassembly. Setup involves mounting the detector, pairing via QR code scan, and configuring sensitivity levels through the Ajax app. The entire process typically takes just minutes per detector.
What maintenance is required and how often?
The MotionProtect Plus requires minimal maintenance thanks to its 5-year battery life and tamper-resistant design. Battery replacement can be performed without opening the enclosure, and the system provides advance low-battery notifications. Regular system checks via the Ajax app confirm operational status.
Can the sensitivity be adjusted for different environments?
Yes, both sensors offer three adjustable sensitivity levels that can be configured remotely via the Ajax app. This allows fine-tuning for different room sizes, environmental conditions, and specific security requirements whilst maintaining the dual-sensor verification process.
