Ajax DualCurtain Outdoor White Wireless Bidirectional Curtain Motion Detector

Ajax DualCurtain Outdoor (White) - Wireless Bidirectional Curtain Motion Detector

The Ajax DualCurtain Outdoor is a wireless, battery-powered perimeter motion detector built specifically for outdoor use. It watches two directions at once, creating a narrow detection curtain along fence lines, facades, walkways, and driveways rather than flooding an open area with coverage. Designed to integrate with an Ajax security system, it combines long-range wireless connectivity, smart false-alarm filtering, and rugged outdoor construction, making it well suited to Australian homes and commercial perimeters that need reliable detection without nuisance triggers from pets, weather, or passers-by.

Key Features

• Bidirectional curtain detection covering up to 30 metres total range, or 15 metres on each side, using two independent optical systems with dual PIR sensors.
• Independently adjustable zones so each side's detection distance can be tuned separately from the Ajax app to match the site layout and avoid false triggers from moving foliage or nearby footpaths.
• Patented Near Area Detection that angles the upper sensor 40 degrees downward, closing the typical blind spot directly beneath the unit for tighter coverage of doors and windows.
• Pet immunity that filters out the movement of animals up to roughly 80 cm in height when installed and configured correctly.
• Anti-masking protection with dedicated sensors that detect attempts to cover, spray-paint, or obstruct the lenses.
• ELSA and SmartDetect filtering algorithms that cross-check signals from both PIR sensors to distinguish genuine intruders from environmental noise.
• Tamper-resistant housing that triggers an alarm if the device is pried off its mounting bracket.
• Long-range Jeweller wireless protocol with encrypted communication back to the hub over distances of up to 1,700 metres line of sight.
• Up to 4 years of battery life from two included CR123A lithium cells under standard usage.

Built for Outdoor Perimeter Protection

Mounted via the included SmartBracket, the DualCurtain Outdoor is intended for permanent installation on exterior walls, fences, gateposts, or shopfronts. Because its two detection fields run along the protected line rather than out into open ground, it is a strong fit for guarding a boundary, a walkway approach, or the front of a building while ignoring people or animals safely inside the property. It pairs with compatible Ajax hubs and range extenders as part of a broader wireless intrusion detection system covering both indoor and outdoor zones.

Frequently Asked Questions

Which hubs is this detector compatible with?
It works with Hub Plus, Hub 2, Hub 2 Plus, and Superior Hub Hybrid, plus Ajax radio signal range extenders. It is not compatible with the original Hub or with ocBridge Plus/uartBridge integration modules.

Will it false-alarm on my dog or cat?
The detector includes pet immunity that ignores animals up to approximately 80 cm tall when the unit is correctly positioned and configured, though enabling Near Area Detection reduces this immunity close to the device.

How weatherproof is it?
The DualCurtain Outdoor is built for permanent outdoor installation and remains effective across a wide temperature range, from well below freezing to over 40°C, with sealing rated for rain, dust, and everyday weather exposure.
