Optex QXI-ST Outdoor Wide Angle PIR – 862-01-QXI-ST
The Optex QXI-ST Outdoor Wide Angle PIR is a professional wired outdoor motion detector designed for reliable perimeter and intrusion detection around homes, offices, warehouses, commercial premises, estates, and outdoor security zones. As part of the Optex QX Infinity Series, it combines wide-angle detection, compact styling, and advanced false-alarm reduction technology for dependable outdoor performance.
With a 12m detection range and 120° wide detection coverage, the QXI-ST is ideal for monitoring open outdoor areas such as driveways, entrances, gardens, patios, boundary walls, parking areas, walkways, and building perimeters. Its passive infrared detection method is designed to detect movement across the protected zone and trigger the connected alarm system when intrusion activity is detected.
The detector includes selectable mounting height and detection pattern options, allowing installers to configure the unit for multi-level detection or pet-alley detection depending on the site requirement. The pet-alley option removes lower-area detection to help reduce nuisance alarms caused by small animals when correctly installed.
To improve stability in outdoor environments, the QXI-ST uses Optex SMDA logic, which analyses detection patterns and environmental changes to help distinguish between genuine intrusions and false-alarm causes such as vegetation movement or weather changes. Double conductive shielding helps reduce visible light disturbance and radio-frequency interference, improving detection reliability.
The sleek and compact housing is made from UV-resistant ASA material and is suitable for indoor or outdoor wall or ceiling mounting. With IP54 protection and an operating temperature range from -40°C to +60°C, the QXI-ST is built for challenging outdoor security installations.
