Ajax DualCurtain Outdoor White | 2-Way Wireless Outdoor Curtain PIR Detector, 30m Range, Pet Immune

Protect windows, doors, gates, fences, and shopfronts with the Ajax DualCurtain Outdoor White—a bidirectional wireless outdoor curtain motion detector featuring dual PIR sensors on each side for adjustable coverage up to 30 meters total (15m per side) with a narrow 4.5° horizontal angle. This weatherproof device (IP54 rated) creates focused vertical curtains to detect intruders approaching protected perimeters while ignoring animals up to 80cm tall, swaying trees, or passersby, thanks to the ELSA dual-signal analysis algorithm and temperature compensation for reliable performance from -25°C to +60°C. With independent zones for each side, optional Near Area Detection to cover blind spots close to the detector (up to 40° downward), and anti-masking sensors that alert to spray, paint, or covers even when disarmed, it ensures robust perimeter security. Communicates securely via Jeweller protocol up to 1,700m in open spaces, with tamper protection and frequency hopping against jamming. Powered by pre-installed CR123A batteries for up to 4 years, it pairs in seconds via QR code and supports remote sensitivity adjustments, entry/exit delays, and automation scenarios through Ajax apps for iOS, Android, macOS, or Windows—compatible with Hub Plus, Hub 2, Hub 2 Plus, and ReX extenders.

Features:

• Dual Independent Detection Zones: Two PIR sensors per side create narrow curtain zones up to 15m each (total 30m), adjustable independently via toggles for precise perimeter protection without false alarms from distant movements.
• Optional Near Area Detection: Patented technology adds a downward 40° sector from the upper PIR sensor to cover blind spots near the detector, ideal for facades, gates, or complex structures.
• Pet Immunity Up to 80cm Tall: Advanced ELSA algorithm analyzes dual IR signals to ignore animals, birds, or environmental interferences like wind or sunlight, focusing on human intruders.
• Anti-Masking Protection: IR masking sensors detect obstacles, spray, or covers on lenses, triggering tamper alerts even in disarmed mode for proactive sabotage prevention.
• 1,700m Two-Way Jeweller Communication: Secure bidirectional protocol with 6.35mW max power and frequency hopping ensures reliable alarms up to 1,700m, with motion speeds from 0.3-2 m/s.
• Up to 4 Years Battery Operation: Pre-installed CR123A batteries with low-level alerts support extended use; IP54 enclosure withstands dust, rain, and temperatures from -25°C to +60°C.
• Tamper and Jamming Resistance: Accelerometer-based tamper triggers on detachment or opening; jamming detection switches channels with encrypted transmission for uninterrupted security.
• Fast QR Code Pairing & App Control: Connects to Ajax hubs in under 30 seconds; remotely configure sensitivity, delays, and scenarios via apps, with real-time testing and event logs.
