Add controlled 850 nm infrared light to camera scenes that need coverage after visible lighting falls below usable levels. IQSIGHT IIR-50850-SR uses six interchangeable diffuser lenses to match illumination to the camera field of view: 10°, 20°, 30°, 60°, 80°, or 95°. Adjustable IR intensity from 10 to 100 percent lets installers reduce excess foreground illumination and tune output for the scene. At its narrow 10° setting, the illuminator is rated for up to 510 ft (156 m); wider beam settings trade range for broader coverage. An adjustable photocell provides automatic day/night switching, with sensitivity configurable from 20 to 70 lux. Telemetry input and photocell output support integration with external surveillance-system controls. The unit accepts 12–32 VDC or 24 VAC ±10% input and consumes 13 W. A 9 ft (3 m) cable provides the connection lead from the illuminator to the selected power source or control point. The anodized aluminum enclosure carries an IP66 rating for outdoor exposure and operates from -58 to 122 °F (-50 to 50 °C). Its polycarbonate front window combines high transmission with vandal-resistant construction and a self-cleaning surface treatment. An adjustable black powder-coated stainless steel U-bracket is included for aiming the illuminator at the protected area. This short-range configuration suits entrances, gates, lanes, perimeters, and other camera views where beam width and IR intensity need to be selected for the installed lens and scene.
