Bosch IIR-50940-SR Concise Descriptor

Overview

The Bosch IIR-50940-SR is a short-range, 940nm infrared illuminator designed to enhance low-light and nighttime video surveillance performance. Its adjustable beam angles and intensity allow you to precisely match illumination to camera capabilities and scene coverage, preventing overexposure or underexposure. This unit is ideal for extending the effective range of cameras in environments like loading docks, parking areas, or perimeter fences where ambient light is insufficient for clear imaging after dark. The 940nm wavelength is considered covert, minimizing visible red glow often associated with lower-wavelength IR sources.

Compatibility

This illuminator is designed for use with IP cameras that feature 1/1.8-inch or larger sensors and have a maximum IR sensitivity range of 940nm. It is compatible with cameras requiring up to 13W of power and can be integrated with systems supporting 12 to 32 VDC input. Specific camera models are not listed, but its broad compatibility makes it suitable for many Bosch and third-party surveillance cameras operating in challenging light conditions.

Installation Notes

Installation requires a 12 to 32 VDC power source capable of delivering at least 13W. The unit includes a stainless steel U-bracket for mounting, with dimensions of 110 x 125 x 35 mm. The illuminator itself measures 110 x 68 x 75 mm. A 3-meter (9 ft) power cable is provided. The photocell sensitivity can be adjusted between 20 lx and 70 lx to control activation based on ambient light levels. The housing is constructed from anodized aluminum extrusion with a polycarbonate front window, rated IP66 for dust and water ingress protection and IK09 for impact resistance.
