Thermal imaging cameras were credited with saving multiple lives per year through victim identification and removal from low visibility conditions as early as 1999. They can be used to search for victims outdoors on a cool night, spot smoldering fires inside a wall, or detect overheating electrical wiring. Since thermal imaging cameras can "see" through darkness or smoke, they allow firefighters to quickly find the seat of a structure fire, or see the heat signature of visually obscured victims.

Preliminary recommendations from the field include visible low-battery warnings, ability to withstand full immersion in water, and the ability to provide meaningful visual readouts beyond 2,000 ☏ (~1,100 ☌).

Army Night Vision Laboratory has contributed to the effort. The National Institute of Standards and Technology Fire Research division is the lead government agency developing performance standards for fire service thermal imaging cameras in the United States, although the U.S. The majority of thermal imaging cameras in use in the fire service are handheld models.

A handheld camera requires one hand to position and operate, leaving only one free hand for other tasks, but can be easily transferred between firefighters.

Ĭameras may be handheld or helmet-mounted. Many thermal imaging cameras use grayscale to represent normal temperature objects, but highlight dangerously hot surfaces in different colors. The camera display shows infrared output differentials, so two objects with the same temperature will appear to be the same "color". These parts work together to render infrared radiation, such as that given off by warm objects or flames, into a visible light representation in real time. Fire-service specific thermal imaging cameras incorporate these components in a heat-resistant, ruggedized, and waterproof housing. Their extremely high resolutions, excellent accuracy, and large ranges enable them to pick out temperature variations throughout a structure.A thermal imaging camera consists of five components: an optic system, detector, amplifier, signal processing, and display. Most of these thermal cameras have large internal memories and even wireless connectivity for simple data transfer.įinally, the high-spec thermal camera models have specific applications in building surveying. There are even FLIR cameras that integrate digital visuals into the on-screen thermograph to create a more true-to-life image. Typically, they feature an additional digital camera which can take visual images to go alongside the thermographs to enable easier analysis. Mid-range thermal cameras have greater thermal resolution and more advanced analytic capabilities. Nevertheless they still have multiple applications such as detecting overheating components in electrical installations, finding moisture leaks from HVAC systems, and detecting gaps in insulation in buildings. We stock a wide range of cameras from FLIR, Testo, Chauvin Arnoux, Martindale and Fluke which vary in thermal resolution, temperature measurement range, and analytic capabilities.Īt the lower-spec end of the range, cameras provide a basic thermal image which tend to have a lower resolution and lesser temperature range. Thermal imaging cameras are an extremely useful tool for multiple applications across the engineering, motor, electrical, marine and HVAC sectors.
