Step 4 : Check Camera and illuminator Settings
 Ensure all tests are undertaken by a qualified, trained engineer. Ensure
safe working practices are followed at all times.
 Check if the camera and illuminator are aligned correctly.
 For Infra-Red illumination, ensure that a Day and Night or Black and
White camera is used and that the camera switches correctly into night
mode.
 Check camera and lens. Is iris fully open at night and set correctly.
Ensure camera is fully operational and has correct night time settings
and capability.
 Ensure correct illuminator lens angle selected for required distance –
check stated performance.
If the angle is too narrow it may cause hot spots and the aperture of
the camera lens to close down. Too wide and there may be insufficient
light on scene and light going where it is not needed.
 Check Camera model number to Raytec performance specification to
ensure required distance is achievable
