5. 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 MEGA LED IR illuminators is based on a camera light sensitivity of 0.01 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. Use water with a little
washing-up liquid.
6. Description of IR illuminator
For ceiling or wall installation, use the ceiling/wall bracket supplied as an optional accessory. Proceed as follows:

2. Connect the infrared illuminator to a stabilised 12V DC power source with sufficient power (up to 36 Watt,
depending on the model).
Check for correct polarity: red/brown (+), blue/black (–).
3. Mount the infrared illuminator on the wall/ceiling bracket.
Adjust the direction of the infrared illuminator and fix the position.
