All objects, both natural and manmade, emit infrared energy as heat. By detecting very subtle temperature differences of everything in view, infrared (or thermal imaging) technology reveals what otherwise would be invisible to the naked eye. Even in complete darkness and challenging weather conditions, thermal imaging gives users the ability to see the unseen.

First developed for military purposes, thermal imaging has since been adopted by law enforcement, fire and rescue teams and security professionals. This technology can be used to detect approaching people or vehicles, to track the footsteps of a fugitive or to learn why a fire resists extinguishment.
