Ajax MotionProtect Outdoor (Jeweller) – Wireless Outdoor Dual-PIR Motion Detector with Anti-Masking & Pet Immunity (White, 9NA)

Product Overview

The Ajax MotionProtect Outdoor Jeweller (SKU: 28302.33.WH3, 9NA region frequency) is a heavy-duty wireless outdoor dual-PIR motion detector engineered to protect building perimeters, courtyards, driveways, and open exterior areas before an intruder reaches the structure. Utilizing an advanced two-sensor optical system with an adjustable detection distance ranging from 3 to 15 meters (10 to  50 ft), it creates an impenetrable outdoor detection barrier with a broad 90° horizontal field of view.

Powered by proprietary LISA (Live Intelligent Spectrum Analysis) digital correlation algorithms, MotionProtect Outdoor analyzes the spectral characteristics of moving objects simultaneously across both PIR sensors to prevent false alarms from pets up to 80 cm in height, swaying branches, birds, and thermal air currents. Communicating over the secure Jeweller wireless radio protocol across open-space distances up to 1,700 meters (5,500 ft), the device delivers instant 0.15 s alarm signaling, Grade 3 active anti-masking protection, an IP55 weather-resistant enclosure, and up to 5 years of autonomous battery life on pre-installed CR123A lithium batteries (with support for optional external 12 VDC power) in a clean matte white finish.

Key System Features & Functionality

• Dual-PIR Optical Detection System: Two independent PIR sensors evaluate moving thermal signatures in parallel to ensure accurate human intrusion detection while ignoring ground-level disturbances.

• LISA False Alarm Prevention Algorithm: Digital two-stage signal analysis compares waveforms from both optical sensors in real time to filter out pets, birds, falling leaves, and sun reflections.

• Grade 3 Active Anti-Masking System: Continuous infrared scanning monitors for attempts to cover, spray paint, tape over, or place objects in front of the lenses (24/7, even when the system is disarmed).

• Adjustable Detection Range: Mechanical distance slider on the rear panel enables simple manual calibration of detection distance from 3 to 15 meters (10 to 50 ft).

• Weatherproof IP55 Enclosure with Hood: Sealed UV-resistant casing equipped with an integrated protective Hood shields lenses against snow, driving rain, dust, and direct sunlight.

• Dual Power Architecture: Operates completely wire-free for up to 5 years on 2 x CR123A lithium batteries or connects to an external 12 VDC auxiliary power line.

• Sabotage & Tamper Defense: SmartBracket mounting base includes an integrated tamper switch that reports unlatching or dismounting immediately to the Ajax app and CMS.
