Semi-covert infra-red illuminators for near-invisible surveillance.
Semi-covert infra-red illumination produces a dull red glow that is unnoticeable in most cases. Most CCTV cameras are only sensitive to 850nm Infra-Red. For a completely covert illuminator, please see the covert illuminator section and check that your camera is sensitive to 940nm covert Infra-Red.
