DualCurtain Outdoor

Description DualCurtain Outdoor Jeweller

The AJAX DualCurtain Outdoor Jeweller is the quintessential perimeter defense sentinel, engineered to establish an impenetrable, bidirectional digital barrier around any property. This advanced wireless detector integrates four separate Passive Infrared (PIR) sensors—two on each side—to project two distinct, narrowly focused "curtains" of detection, securing façades, gates, and critical entryways across a combined range of up to 30 meters.

Its operational intelligence is defined by the proprietary ELSA (Extended Live Signal Analysis) algorithm. This system requires simultaneous activation of both PIR sensors on the same side before a confirmed alarm is triggered. This sophisticated, two-factor authentication process effectively eliminates false alarms stemming from passing pets (up to 80 cm), wind-driven foliage, or minor weather disturbances. Further ensuring its integrity, the DualCurtain offers independent adjustment of distance and sensitivity for each side and incorporates robust IP54-rated housing, anti-masking technology, and anti-tamper protection, cementing its status as the most precise and reliable solution for critical, pre-intrusion warning.

Key Features and Operational Highlights:

• Bidirectional Curtain Defense: Integrates four PIR sensors (two per side) creating two independent detection curtains with a combined range of up to 30 meters.

• Intelligent False Alarm Immunity: Driven by the ELSA Algorithm, requiring simultaneous activation of both sensors on one side to confirm an intrusion, filtering out environmental noise.

• Precision Customization: Detection distance, direction, and sensitivity are independently and precisely adjustable for both the left and right sides.

• Anti-Sabotage: Features an active Anti-Masking System to detect attempts to obscure the view, alongside tamper protection against unauthorized removal.

• Protocol Superiority: Leverages the highly reliable Jeweller wireless technology for encrypted, stable, long-range communication (up to 1,700m).

• Environmental Resilience: Robust IP54-rated housing ensures reliable operation across extreme temperature variances.
