Silent Witness releases the LumaView IR 75 infrared illuminator. It offers mission-critical monitoring in low-light or completely dark conditions and enables IR-sensitive CCTV cameras to produce high-quality images under night-time conditions without imposing intensive, obtrusive visible light illumination. The IR 75 illuminator is weather sealed for indoor or outdoor use and works with distances of up to 90 meters. It is offered with three types of filters to suit specific applications. Overt illumination produces a distinct red glow that warns of the presence of IR light (715nm). Semi-covert illumination produces a faint red glow that can be detected with a trained eye (850nm). Full-covert illumination avoids any red glow, making it impossible to detect the presence of IR light (950nm).
