Infrared Illuminators (I.R. Illuminators)
Cameras respond to light, however adequate light is not always possible. In
those cases another source is needed to allow the camera to "see" in the
dark. Infrared Illuminators are designed to light an area for the cameras
without the need for artificial lights. This also helps in areas where
covert surveillance is required, because the light waves are not in the
visible range and cannot be seen. (Note: The closer the nanometer rating to
the 700nm barrier, the more visible the light may be. The lowest
nanometer rating, 850nm, is just visible at the light source itself. The
940nm models are invisible to the naked eye). IR illuminators are much less
expensive than regular lights, and require less maintenance.
