A favorable point to be noted is that human eye is not sensitive to human eye and so, these sources are not detected by anybody in the area. Good infrared cameras which can light up about 100 ft are easily available in the market.
Another kind of night vision security camera features thermal energy. These cameras are considerably more expensive when compared to infrared based security cameras but are far more useful too. They usually work in a unique way. They detect the heat that is radiating off an object or a human and then convert it into an image. The image generally consists of false colors indicating the levels of the heat. The interesting thing is that these kinds of cameras do not need an illumination source. Such cameras are widely used by the military. They are also used in the factories and plants where temperature monitoring is crucial keeping track of performance of the factories’ equipment.
