Thermal imaging camera is also called thermal imager or infrared thermal imaging camera. It is a kind of equipment for photosensitive imaging of infrared rays emitted by objects. This equipment is widely used in military, fire protection, industrial production, customs inspection. Also, vehicle mounted thermal camera can be used for patrolling and law enforcement.

Common thermal imaging cameras are: short-wave and long-wave thermal imaging cameras. 

Shortwave, the spectrum range is 3-5um, usually as cooled infrared thermal imaging camera, the material is generally InSb, HCT. Long wave, the spectrum range is 8-14um, usually as uncooled infrared thermal imaging camera, the material is generally: VOx, α-silicon. 

Short-wave infrared thermal imaging cameras are mostly used in the military field. The resolution is generally high and the cost is relatively high. It usually takes about 10 minutes for the cooled thermal imaging camera to be able to use. 

Long-wave infrared thermal imaging cameras are widely used in border and coastal defense, airports, perimeter of oil fields, mines, and forest fire detection/alarm  and other fields with its’ excellent effect.
