The following are some key considerations in determining the best illumination method:
• The requirements will dictate if IR illuminators or visible lighting is used. The cameras used
with IR illuminators must be either B&W or day/night cameras capable of automatically
switching between colour/B&W depending on the conditions. Visible lighting must be used
for colour cameras. The level of lighting required is higher for colour cameras as these have
less sensitivity compared to B&W cameras.
• The sensitivity of the cameras determines the required level of illumination. When visible
illumination is used, the lighting should be sufficient for the human eye to see targets at the
maximum detection range. When using IR illumination, verify the intensity by viewing the
camera output on a monitor.
• It is important to ensure that areas where lighting casts shadows do not provide dark areas
for intruders to utilise.
• Illuminators (visible or IR) should not be positioned to face directly into a camera.
• Typically, the best type of visible lighting is closest to normal daylight, i.e. a white light
source rather than a coloured light source such as sodium vapour.
