6. Notes on using infrared illuminators


Infrared illuminators as a lighting source can only be used together with infrared B/W or day/night cameras.

When IR illuminators are used, there may be a camera focus shift. This can be avoided by the use of IR-corrected lenses.

The range of infrared illuminators depends on the IR sensitivity of the camera model used. The specified ranges of the illuminators
are based on a camera light sensitivity of 0.1 lux.

Objects can appear unusual in IR light. For example, a green field appears dark in daylight (normal light). In infrared light, however,
green light appears almost white.

As for all illumination sources, the infrared illuminators should be installed as near as possible to the area to be monitored. Make
sure that the light direction is adapted to the camera direction and does not dazzle the camera.

Clean the infrared illuminator regularly (at least every three months) since the light strength is reduced by dirt and the lamp cannot
cool so effectively. Do not use any abrasive substances or alcohol for cleaning.
