Thermal imaging cameras were originally created for military use, but now their reach has extended even further. Firefighters use them to see through smoke, find trapped people and hotspots. Law enforcement uses them for surveillance, locating suspects, investigating crime scenes, and conducting search and rescue operations. They are also used by power-line maintenance workers, building construction technicians, home inspectors, and other types of workers.

These cameras aren’t cheap. A good thermal imaging camera can run you anywhere from a couple hundred to a couple thousand dollars. Here you’ll find five cheap, but quality, thermal imaging cameras that won’t put a dent in your wallet.
