MotionProtect Curtain Outdoor

The first line of defense

Curtain Outdoor Jeweller is a motion detector for covering the perimeter of a site with exceptional accuracy and a near-zero chance of false alarms. Featuring a unique optical system, the device looks over narrow sectors of up to 12 m long. Dual motion detection technology engaging two PIR sensors and one Ka-band microwave sensor allows filtering out false alarms caused by thermal noise, animals, or plants. The detection range and pet immunity mode are configured via a slider on the detector’s enclosure, and sensitivity is configured in Ajax apps to meet the specific needs of the site. Pre-installed batteries ensure stable performance for up to three years.

Two operating modes

Curtain Outdoor Jeweller operates in two modes: regular and with pet immunity on. In the regular mode, any motion within the covered area triggers an alarm. The pet immunity mode is designed to ignore the movement of animals up to 100 cm tall and minimize false alarms.

• Without pet immunity
• With pet immunity

Facility-specific motion detection

The device offers up to 12 m of detection range, which, however, can be adjusted to fit the peculiarities of a site. For example, the range can be set for the detector to cover doors and windows yet to ignore high-traffic zones like a walkway. Detection sensitivity levels are also essential to limit false patrol dispatches. Set the sensitivity to low in areas prone to false alarms, medium for most sites, and high in obstacle-free zones where immediate threat detection is crucial.

Two PIR sensors

Curtain Outdoor Jeweller has two PIR sensors to ensure accurate motion detection. The detector does not respond to a movement if only one sensor is triggered. When both sensors detect motion, proprietary digital algorithms come into play. In a fraction of a second, they perform a three-step signal analysis, filter out natural obstacles or animals, and decide whether an alarm should be raised.

K-band microwave sensor

The K-band microwave sensor verifies alarms triggered by PIR sensors. It performs a radio-wave scan of an area to minimize false alarms triggered by thermal interferences. Unlike traditional X-band sensors, the Ka-band sensor offers superior precision and energy efficiency, with significantly fewer false alarms and hardly noticeable impact on the battery life. Additionally, the sensor is completely safe and poses no threat to health.

Thermal interferences filter

SmartDetect
When the system is in armed mode, the detector constantly analyzes the thermal diagram from the PIR sensors, including the IR radiation intensity, thermal spot size, movement speed, time spent in the detection zone, and other parameters. The SmartDetect software algorithm identifies false alarm markers instantly and with high accuracy. As a result, the device accurately responds to human movement without false alarms.

Temperature compensation

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

Sensitivity level

Curtain Outdoor Jeweller has in-app sensitivity settings. Low sensitivity makes the detector less likely to respond to interferences, while high sensitivity ensures an alarm is raised in case of any movement in the detection zone. Set up the needed sensitivity level to avoid costly patrol dispatches to false alarms.

Professional installation

With the correct installation, the detector performs with high precision. The device should be perpendicular to the ground level, while the potential path of an intruder should be perpendicular to the axis of the detector’s lens. When configured with the correct operating mode, sensitivity, and detection range, Curtain Outdoor Jeweller instantly responds to real threats and generates barely any false alarms.
