Superior MotionCam AM (PhOD) Jeweller

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 manufactured devices. This approach ensures the utmost accuracy of intrusion detection.

A new optical system design prioritizes maximum security. Like other Ajax motion detectors, Superior MotionCam AM (PhOD) Jeweller uses a PIR sensor and a Fresnel lens to detect thermal noise and avoid false alarms. The detector features consistent sensitivity throughout the entire detection area and a reduced blind zone¹ of up to 2.6 ft. Since the detection zone extends from floor level to full human height, the detector does not support the pet immunity feature. This allows it to reliably detect any intruder, regardless of whether they are running, crawling², or walking slowly. The specialized pattern of Fresnel lens sections provides the detector with precise information about thermal objects and their movement.

We processed thousands of thermal patterns caused by people 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 filters out potential false triggers such as headlights, lighting devices, and heat flows instantly and with high accuracy. As a result, the detector accurately responds to movement without false alarms.

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.

The detector’s sensitivity can be adjusted via Ajax apps to match specific site conditions. PRO users can choose from four sensitivity levels to balance detection accuracy with false alarm prevention. Lower sensitivity works well in spaces with potential thermal interference, such as areas near heating equipment or in direct sunlight. Higher sensitivity is recommended for spaces requiring enhanced security, while the very high setting ensures detection of even the slightest movement in the protected 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.

With the proper installation at the height of 7.9 ft and lens direction perpendicular to an alleged intrusion path, Superior MotionCam AM (PhOD) Jeweller provides an accurate thermal diagram. It instantly responds to a real threat, minimizing false alarms. The detector is available exclusively to Ajax Systems authorized partners who have completed specialized training. This ensures reliable device operation and maximum security of the protected area.
