MotionProtect Plus U Jeweller

Wireless PIR motion detector with an additional K-band microwave sensor

Product is not available in your region

Precise motion detection in a complex environment

MotionProtect Plus U Jeweller is a wireless motion detector equipped with an additional microwave sensor for enhanced accuracy. It detects the movement of objects with temperatures similar to those of the human body. When motion is detected, the device performs an RF scan of the area using its built-in K-band microwave sensor. This approach helps prevent false alarms caused by thermal radiation emitted by objects, such as air conditioners or fireplaces.

PIR sensor

All Ajax motion detectors use PIR sensors by Excelitas Technologies, a field-leading American manufacturer specializing 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 the manufactured devices. This approach ensures the utmost accuracy of intrusion detection.

PIR sensor

K-band microwave sensor

The K-band microwave sensor scans a room to minimize false alarms caused by thermal radiation. 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 lifespan and significantly fewer false alarms. Additionally, the sensor is completely safe and does not harm human health.

Special lens

The pattern of the Fresnel lens sections is designed to differentiate between the IR diagrams of people, animals, and objects that can cause false alarms. Large lens sections capture radiation at the level of an adult’s head and torso, while the smaller sections make the diagram more detailed. The lens provides the detector with accurate data on thermal objects in the detection zone and the nature of their motion.

Thermal interference filter

SmartDetect

We processed thousands of thermal patterns caused by people, pets, and the environment to develop the SmartDetect software algorithm. In armed mode, the detector constantly analyses 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 filters out false alarm triggers instantly and with high accuracy. As a result, the detector accurately responds to human motion without false alarms.

Temperature compensation

Temperature compensation is a software mechanism that maintains the contrast of the thermal diagram even if the ambient temperature is close to the temperature of the human body. With each ambient temperature measurement, the detector adjusts the PIR sensor data according to the coefficient table stored in its memory. The detector is effective over the entire operating temperature range.

Temperature compensation

Sensitivity level

The detector features four sensitivity levels that can be adjusted in an Ajax app. PRO users can choose from three sensitivity levels to balance detection accuracy with false alarm prevention. Low sensitivity makes the detector less likely to respond to an active pet. With high sensitivity, an alarm is raised whenever there is any movement in the detection area. The optimal setting can be determined during installation via the detection zone test. The setting can be adjusted at any time when the system is disarmed if environmental conditions change or false alarms occur.

Sensitivity level

Professional installation

When installed properly at a height of 2.4 m and with the lens facing directly toward a potential intrusion path, the detector provides an accurate thermal diagram and is immune to pets. It instantly responds to real threats, minimizing false alarms caused by pets that weigh up to 20 kg and are under 50 cm in height.

Professional installation

Stable and reliable performance

MotionProtect Plus U Jeweller is equipped with a high-quality battery from proven manufacturers only. In addition to real-time testing during battery production, Ajax Systems inspects every unit to ensure the accuracy of the batteries’ characteristics. The battery provides stable performance at temperatures from –10 °C to +40 °С.

Jeweller

Unique wireless technology

Jeweller is Ajax’s proprietary radio protocol for secure two-way communication. It provides block encryption and device authentication during each communication session with an Ajax hub or radio signal range extender. Jeweller prevents sabotage, spoofing, and data theft.

Communication through steel and concrete

Some facilities have thick walls, metal partitions, or sheer distances that affect signal quality. Ajax range extenders are designed to increase the range of a wireless network and deliver stable connection with a hub despite the obstacles. And by choosing the model with an Ethernet cable connector, you get an additional communication channel. А single system can accommodate up to five range extenders.

Up to 5 range extenders within one system

Ethernet-equipped model available

System supervision

The device performs automatic self-diagnosis and reports its state to the hub. Essential parameters, including tamper, communication, power supply, and sensor states, are continuously monitored. The Ajax Cloud server controls communication between the hub and Ajax apps, ensuring instant notifications for ARCs and users. In case of any malfunction or communication failure, an engineer is informed immediately to provide necessary services.

Tamper alarm

Tamper alarm

MotionProtect Plus U Jeweller has a tamper button that detects if the device is detached from the mounting panel or removed from the surface. The system instantly alerts the monitoring company and users to device dismantling. A holding screw helps to secure the device on the mounting panel.

Data encryption

Data encryption

All data stored and transmitted in the system is protected by block encryption featuring a dynamic key. This encryption provides protection against data theft, spoofing, and software tampering.

Informative notifications

Informative notifications

An Ajax system instantly informs monitoring companies and users about alarms and events. The notifications include precise details about each incident, including time, location, and the triggered device.

Device authentication against spoofing

Device authentication against spoofing

To authenticate the detector, the hub checks its unique parameters during each communication session. If any parameter fails the check, the hub ignores the device commands.

Regular polling

Regular polling

The detector regularly exchanges data with the hub. The system controls the device’s state and reports any malfunction or communication loss.

Communication loss detection

Communication loss detection

With a minimal polling interval (3 data packages every 12 seconds), it takes only 36 seconds to detect communication loss and notify the monitoring company and users of the incident.

Effortless installation and setup

MotionProtect Plus U Jeweller is ready to operate straight out of the box. Using the SmartBracket panel, an installer can effortlessly mount the device, eliminating the need to disassemble the enclosure. Ajax apps help quickly make the device part of the ecosystem: simply scan the QR code to add the device to the hub. All settings can be configured remotely. Therefore, on-site visits are not needed.
