Ajax MotionProtect Plus Wi-Fi Jeweller Black
Wireless IR motion detector with an additional K-band microwave sensor.
Precise motion detection in a complex environment
MotionProtect Plus Jeweller is a wireless IR motion detector featuring a dual detection technology comprising PIR and microwave sensors. The microwave sensor is activated solely to confirm the detection triggered by the PIR motion sensor, ensuring precise detection even in areas with significant thermal interference, like those with active air conditioners or fireplaces. With a sleek design, detectors are seamlessly integrated into any space. Installation is simplified with wireless capabilities and the SmartBracket mounting panel, while remote configuration eliminates the need for on-site visits to resolve minor requests.
No intruder goes unnoticed
PIR sensor
All Ajax motion detectors use PIR sensors by Excelitas Technologies — a field-leading American manufacturer which specializes in designing and producing optronic components since 1931. Ajax Systems constantly proves the sensor's superior quality at the production stage: we test 100% of manufactured devices. Wrapped into Ajax technologies, the sensors bring the utmost accuracy of intrusion detection.
K-band microwave sensor
The K-band microwave sensor scans a room to minimize false alarms triggered by thermal interferences. Operating in conjunction with the PIR sensor, it uses microwave technology only for PIR sensor alarm verification. Unlike traditional X-band sensors, the K-band sensor offers enhanced precision and superior energy efficiency. This results in minimal impact on battery life and significantly fewer false alarms. Additionally, the sensor is entirely safe, posing no harm to human health.
Special lens
The pattern of the Fresnel lens sections is designed to differentiate between the IR diagrams of a human, animal, and thermal noise. Large lens sections capture radiation at an adult's head and torso level. Smaller sections make the diagram more detailed. The lens provides the detector with accurate information about the thermal object in the detection zone and the nature of its movement.
Thermal interferences filter
We processed thousands of thermal patterns caused by humans, animals, and the environment to develop the SmartDetect software algorithm. In armed mode, the detector constantly analyzes the thermal diagram from the PIR sensor, including the IR radiation intensity, thermal spot size, movement speed, time spent in the detection zone, and other parameters. The algorithm identifies false alarm markers instantly and with high accuracy. As a result, the detector accurately responds to human movement without false alarms.
Temperature compensation
Temperature compensation is a software mechanism keeping the thermal diagram contrast even if the ambient temperature is close to the temperature of the human body. With each ambient temperature measurement, the detector corrects the PIR sensor data according to the coefficient table stored in its memory. The detector is effective over the entire operating temperature range.
Sensitivity level
The detector can adapt to the conditions of a particular facility, considering possible thermal interference or pets. The sensitivity setting changes the set of markers by which false alarms are filtered. Low sensitivity makes the detector less likely to respond to an active pet. A high sensitivity will raise the alarm in case of any movement in the detection zone.
Professional installation
With the correct installation at the height of 2.4 m and lens direction perpendicular to an alleged intrusion path, the detector provides an accurate thermal diagram and pet immunity. It instantly responds to a real threat, minimizing false alarms caused by animals weighing up to 20 kg and below 50 cm in height.
Wire-free flexibility and reliable performance
Baseline devices operate without any wires, offering maximum flexibility during installation. The pre-installed CR123A battery from proven manufacturers ensures a hassle-free setup, requiring no additional steps to start operating the devices. In addition to real-time testing during battery production, Ajax Systems inspects every unit to ensure the accuracy of the battery characteristics. The battery is easily replaceable, allowing one to swap them out after approximately five years of autonomous operation. The battery status is always accessible via the Ajax app. Users and security companies receive low battery level warnings months in advance, allowing for timely replacement without rushing.
Unique wireless technology
The Ajax system uses secure two-way radio communication based on the Jeweller proprietary protocol. It supports block encryption and device authentication on every session with the hub to prevent sabotage, spoofing, and data theft.
