Thermal Imaging Cameras have a variety of uses. Some thermal imaging camera models that can be used for general troubleshooting and inspection including building envelope, restoration and remediation, inspection and roofing applications. Higher end thermal imaging cameras are typically used by military and law enforcement personnel as well as firefighters. Firefighters find thermal imaging cameras especially helpful because they "see" through smoke and haze and locate hot spots where fire may be hiding.
You may have heard the term FLIR (forward looking infrared) before and even noticed some of their cameras mounted underneath helicopters. Sometimes these thermal imaging cameras make it to the big screen or on television because they are very effective at showing heat and therefore finding hiding criminals. I've seen thermal imaging cameras on COPS and many other real life police hunt type shows.
Thermal imaging is not only for catching bad guys. Home inspectors often times use thermal imaging cameras to identify areas of heat loss in a structure that can be fixed or insulated, saving property owners quite a bit of money.
If you are in the market for a thermal imaging camera, take a look at these models and see if something meets your needs.
