What is a thermal or IR camera and what is it capable of?
A human eye is unable to see things in the dark. The Infrared light is useful to see things in the dark because it is based on a principle of thermal imaging.It emits infrared light which makes it visible. It is used in different areas like X-raycamera, surveillance camera.
I am using AXTON IR illuminator . I find it very useful at night surveillance. If you are thinking of buying any IR illuminator then go for it.

An IR (infrared) camera, also known as a thermal camera, shows you changes in, or differences in, temperature on the surface of the target. More experienced and trained users can use it to measure exact temperatures. It’s often used for preventative maintenance applications, like detecting hotspots in switchgear, and for home inspections, to detect heat loss. IR/thermal cameras do not work like x-ray cameras, which is a common misconception.
