Thermal cameras, as the name implies, show the use a portrait of the heat signatures in the area of the screen. Since people, animals, and even plants give off heat, they can be identified via this type of camera, even in the dark or behind walls. This tool is portable. There are even apps for thermal imaging that you can download onto your smart phone. The information it provides can be invaluable in a variety of diverse professions.

1. Firefighting. Thermal imaging can tell firefighters where people are located in a burning building even when smoke and darkness hamper normal vision, allowing them to get to them more quickly. This tool can also help firefighters identify hot spots and hidden flames behind walls, keeping firefighters out of harm's way.

2. Law Enforcement. A thermal camera has a myriad of uses for law enforcement personnel. This device can help them find fugitives hiding in places like behind bushes or in closets. It can help with surveillance, especially in the dark. The camera can also help them quickly find people who have been injured in accidents and perhaps thrown from the vehicle. Police can find hidden compartments that criminals may use to stash drugs or weapons, and it will aid law enforcement in other types of search and rescue operations, such as after a flood, tornado or earthquake.

3. HVAC contracting. Thermal imaging can also be very useful to those in the heating and cooling industry. By pointing a thermal imaging device at windows and doors, a contractor can easily tell where a homeowner is losing heat from his or her home and offer ways to correct the situation. Thermal imaging can also be used to locate mold and mildew, since these are live organisms and, thus, give off a heat signature.

4. Farming. Farmers can also be aided by using thermal imaging. These devices can help locate lost livestock, even in the dark and help to track of herds.

5. Veterinarians. Large animals can be difficult to treat, since getting them to the necessary monitoring equipment can be tricky. Thermal imaging lets a vet see if the animal has a higher temperature than normal and help to identify the site of an infection or may other ailments.

Thermal cameras are more than just fascinating toys. These high-tech devices can assist workers in a number of professions, such as fire fighting, law enforcement, rescue, veterinary medicine, and even farming.
