Key Features

Why choose Ajax DualCurtain Outdoor Jeweller?

Professional-grade hardware engineered for reliable performance in Canadian climate conditions.

🚧
Dual Curtain Detection Zone
Two independent PIR sensors create overlapping vertical detection planes — an intruder must cross both to confirm an alarm, dramatically reducing false triggers.
🌿
Weather & Vegetation Filtering
Advanced algorithm distinguishes swaying branches, rain, and small animals from human movement — reliable outdoor operation 24/7.
🐾
Pet Immunity
Low-profile detection zone is configured to ignore animals — cats, dogs, and wildlife passing at ground level do not trigger alarms.
🚫
Anti-Masking
Detects attempts to block the optics with tape, spray, or physical obstruction — triggers immediate tamper alarm.
🌧️
IP55 All-Weather
Sealed housing rated for Canadian outdoor conditions — rain, snow, frost, and summer humidity.
📏
30 m Narrow Zone
Narrow curtain detection pattern covers the full height of a door or gate up to 3 m, reaching 30 m along a fence line.
