The Argus 3 Thermal Imaging Camera is an excellent example of how good design can be a matter of life or death. New and improved technology necessitated the redesign of the original Argus camera, an infrared imaging system that allows the user to see through smoke and total darkness. In order to fully understand the needs of the end-user, the design director undertook comprehensive firefighting training, which led to making accessibility and compactness priorities in the redesign.
