Infrared radiation (Infrared (IR): English) Named as red or ultraviolet radiation under heat wave length electromagnetic waves and light waves are between radio frequency in the range 1014 Hz frequency 1011 – in the same microwave range. Has wavelength between the red light with radio waves of all kinds of matter at temperatures between-200° c up to 4000 degrees Celsius will be releasing infrared out. Specific properties of infrared, such as no deviation in the electromagnetic fields that are different, it is a property that depends on the frequency, the higher the frequency, the greater is the high power, high.In order to make use of the tools and systems used in remote control (remote control) to create an infrared camera can see objects in the dark, for example, States can use infrared camera sees via fall camps since war Viet Nam and many types of eyes recognized this type of radiation. Make visible or prey on the night.
