The term FLIR is an acronym for the abbreviation Forward Looking InfraRed. State-of-the art FLIR thermal imaging camera systems are equipped with different cooled and uncooled two-dimensional imaging detectors that reproduce thermal images in the wavelength ranges of (2 ... 14 µm). This makes FLIR thermal imaging camera systems ideal for people and vehicle detection in government applications, other applications include e.g. industry and research.
