Infrared (IR) illuminators are typically used when ambient light is either not present or too dim. Sometimes an IR camera's IR array is too narrowly focused or not strong enough, in that case an external IR illuminator can provide an extra source of invisible infrared light. Many black and white cameras are sensitive to infrared light, where as only certain color cameras have a the ability to switch to black and white mode in low light conditions.
