Ajax MotionProtect Outdoor

MotionProtect Outdoor Jeweller is a wireless outdoor motion detector. Its adjustable motion detection distance is up to 15 meters. It has an anti-masking system that detects attempts to block the detector view. When installed and set up correctly, the detector does not react to animals up to 80 cm tall.

MotionProtect Outdoor Jeweller is a wireless outdoor motion detector. Its adjustable motion detection distance is up to 15 meters. It has an anti-masking system that detects attempts to block the detector view. When installed and set up correctly, the detector does not react to animals up to 80 cm tall.

The detector is compatible with all Ajax hubs and radio signal range extenders. Connection to ocBridge Plus and uartBridge integration modules is not provided.

MotionProtect Outdoor operates as part of the Ajax system by connecting to the hub via the secure Jeweller radio protocol designed to transmit alarms and events. The hub communication range is up to 1,700 meters without obstacles.

Operating principle

MotionProtect Outdoor detects motion using two built-in infrared (IR) sensors, capturing moving objects with temperatures close to that of the human body.

As soon as an armed detector identifies motion, it instantly sends an alarm to the hub. The hub, in turn, activates the connected sirens, activates scenarios, and notifies the security company and the users.

Users know exactly where motion is detected. The notifications contain the name of the hub (the name of the protected facility), the name of the device, and the virtual room to which the detector is assigned.

Protection against false alarms

Like Ajax indoor detectors, MotionProtect Outdoor uses the SmartDetect algorithm for protection against false alarms.

Thanks to this algorithm, the detector analyzes the thermal diagram read by the sensor: the intensity of infrared radiation, size of the heat spot, speed of movement, time spent in the detection area, and other parameters.

Normally, at this point, the detector is ready to make a decision: ignore or raise the alarm. But if the situation is not clear, the detector activates the two-step LISA algorithm. This is how it works: as soon as both IR sensors detect movement, LISA performs correlation and spectral analysis of the signals, distinguishing between real threats and interferences.

Correlation analysis

Each time a motion is detected, the LISA algorithm analyzes and compares the waveforms of two signals from the infrared sensors in real time. If they are similar, the detector raises the alarm.

Spectral analysis

When both IR sensors detect motion but correlation analysis does not reveal the sufficient similarity of waveforms, LISA compares the frequency components of the signals from the two sensors.
