Infrared Illuminators
Infrared illuminators are used in areas where light is not sufficient for surveillance. They are generally used with black and white cameras since these cameras have greater sensitivity to infrared light. Color cameras that have the capability to auto switch to black and white can take advantage of IR light at night to illuminate dark areas. There are certain cameras that also have a built in IR cut filter that will help in utilizing IR effectively.

Infrared illuminators use light emitting diodes, or LEDs, to transmit light. A single LED produces only a small amount of light so banks of LED’s are used. These banks can last up to 100,000 hours. LEDs are therefore extremely economical as well as efficient.
