Lightning-fast alarms. Verified.
MotionCam U Jeweller is Ajax’s PIR motion detector with camera, adapted to comply with UK regulatory requirements. The built-in camera captures photos when motion is detected, delivering visual evidence of alarms to the Ajax app within 9 seconds1. HDR technology ensures clear detail even in challenging lighting conditions. These features enable quick alarm verification, helping to reduce unnecessary patrol dispatches and ease user anxiety.

More than a photo. Faster than a video.
MotionCam U Jeweller starts capturing images the moment motion is detected — even before the intruder knows they are caught. An animated series of photos is sent instantly, following the alarm, allowing users to assess the situation quickly. Thanks to HDR technology, the camera delivers clear visuals in both bright and dark environments. To achieve this MotionCam U Jeweller takes two photos at different exposure levels and uses a special algorithm to merge them into a single, balanced frame with optimal lighting and detail.

Privacy first
Ajax product portfolio also includes MotionCam U (PhOD) Jeweller with extended photo verification possibilities. This detector also supports Photo on Demand, Photo by Scenario, and Photo by Schedule features.
HDR for challenging lighting conditions
MotionCam U Jeweller captures clear, balanced images using an advanced optical system, a CMOS sensor, and HDR (High Dynamic Range) technology. HDR improves colors and contrast by combining photos with different exposures into one. This prevents images from being too bright or too dark. As a result, photos look more colorful, detailed, and natural — just like we see things in real life.
HDR preserves details in both bright and dark areas. Without HDR, windows appear overexposed, and shadows are too dark.

PIR sensor
All Ajax motion detectors use PIR sensors by Excelitas Technologies, a field-leading American manufacturer specialising 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. This approach ensures the utmost accuracy of intrusion detection.
Sensitivity level
The detector’s sensitivity can be adjusted via Ajax apps to suit specific site conditions. PRO users can choose from three sensitivity levels to balance detection accuracy and false alarm prevention. 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. High sensitivity raises the alarm in case of any motion in the detection zone. 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.
Special lens
The pattern of the Fresnel lens sections is designed to differentiate between the IR diagrams of a human, pet, 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 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 identifies false alarm markers instantly and with high accuracy. As a result, the detector accurately responds to movement 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 corrects the PIR sensor data according to the coefficient table stored in its memory. The detector is effective over the entire operating temperature range.
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, minimising false alarms caused by pets weighing up to 20 kg and below 50 cm in height.
Stable and reliable performance
MotionCam U Jeweller is equipped with high-quality batteries 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 batteries provide stable performance at a temperature from –10 °C to +40 °С.

Unique wireless technologies
Ajax systems use two-way secure radio communication based on Jeweller and Wings proprietary protocols. Radio protocols work in parallel and focus on their own function, guaranteeing instant data delivery even in the event of communication interruptions or a weak signal.

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 status to the hub. Essential parameters, including tamper alarms, communication, power supply, and sensor statuses, 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.

Effortless installation and setup
MotionCam U Jeweller is ready to operate straight out of the box. Using the SmartBracket panel, an installer can effortlessly mount the device on the wall, eliminating the need to disassemble the enclosure. Ajax apps help quickly make the device a part of the ecosystem: simply pair the device with the hub by scanning the QR code. It can always be reconfigured remotely without the need for on-site visits.
