Ajax MotionCam U Jeweller

The Ajax MotionCam U Jeweller is a next-generation wireless motion detector with a built-in photo verification camera, designed to deliver instant, reliable intrusion alerts and visual confirmation. Using Ajax’s advanced U-Jeweller wireless technology, it combines high-speed communication, long-range connectivity, and exceptional energy efficiency — making it ideal for both residential and commercial security systems.

When motion is detected, the MotionCam U captures a series of encrypted images and sends them to the Ajax app within seconds, allowing users or monitoring centres to verify alarms visually and eliminate false triggers. Its pet immunity, PIR detection, and anti-tamper protection ensure dependable performance and minimal false alarms in everyday environments.

More than a photo. Faster than a video

MotionCam Jeweller will show the actual situation from the scene even before the burglars understand that they’re busted. An animated series of photos follows the instant alarm for an accurate situation appraisal. MotionCam Jeweller can only take photos in case of an alarm. The detector software architecture does not support taking a photo on demand.

Special lens
The pattern of the Fresnel lens sections is designed so that the diagrams of the infrared radiation of a human, an animal, and thermal noise have significant differences. Large sections of the lens capture radiation at the level of the head and torso of an adult. Smaller sections make the diagram more detailed. The MotionCam Jeweller lens provides the detector with accurate information about the thermal object in the detection zone and the nature of its movement.

Filter for thermal interferences

The detector instantly analyzes the thermal diagram from the sensor: the infrared radiation intensity, the heat spot size, the motion speed, the time spent in the detection zone, and other parameters.

Ajax engineers have analyzed thousands of IR sensor triggerings caused by humans, animals, and thermal interference and developed SmartDetect. The software algorithm finds false alarm markers instantly and with high accuracy. As a result, the detector accurately responds to a human and does not bother the user with false alarms.
