The Ajax DualCurtain Outdoor Jeweller features two independent optical systems with dual PIR sensors, providing comprehensive perimeter coverage. The ELSA algorithm ensures accurate detection while minimizing false alarms, and Near Area Detection addresses blind spots. With an IP54-rated body and up to 4 years of battery life, it offers reliable outdoor security.
Bidirectional Curtain Detection: Two independent optical systems offer a narrow detection range for effective perimeter protection.
Advanced Motion Analysis: The ELSA algorithm analyzes signals to distinguish between human movement and false triggers like animals or swaying plants.
Near Area Detection: Expands coverage close to the detector to address blind spots, ideal for windows and entryways.
Pet Immunity: Ignores small animals, minimizing false alarms.
Weather Resistant: IP54-rated protection ensures reliability in harsh outdoor conditions.
Long Battery Life: Operates for up to 4 years on two pre-installed CR123A batteries.
Extended Communication Range: Jeweller technology provides a communication range of up to 5,600 ft in open space, with performance varying based on obstacles and environmental conditions.
