From a guest post on //dronelife.com by talented Part 107 pilot and writer Kara Murphy.
Drones equipped with thermal imaging cameras can detect changes in temperature. One growing area of interest, that utilizes thermal energy or “heat imaging,” is search and rescue.
Both people and animals can be located thanks to this technology.
The scientific explanation for how this all works is best covered by Wikipedia: “Thermographic cameras detect radiation in the long-infrared range (IR) of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 µm) and produce images of that radiation, called thermograms.”
Companies also use infrared imaging for roof inspections, firefighting, cell tower inspections, and the detection of hazardous materials (HAZMAT).

2. The Infrared Training Center (ITC) does a lot of training of thermographers in support to its owner, FLIR Systems, and their customers. FLIR one of the world’s largest manufacturer of thermal imaging equipment and technology both civilian and military.
3. The Infraspection Institute in New Jersey (//www.Infraspection.com) has the distinction of being the oldest training course supplier for Infrared Thermographers (since 1987). They feature all aspects of training and are independent of equipment suppliers. They focus on the practical aspects of the technologies involved as well as the business of Infrared thermography services. They also offer certified training courses at the three typical levels of expertise as well as a large number of online courses.
