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 12m 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. 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 100cm tall and minimize false alarms. The device offers up to 12m 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.
