First thermographic camera In 1929, Hungarian physicist KÃ¡lmÃ¡n Tihanyi invented the infrared-sensitive (night vision) electronic television camera for anti-aircraft defense in Britain. The first thermographic cameras developed were infrared line scanners.
Agema developed the first commercial infrared scanner, designed for powerline inspections, in 1965, the first battery-operated portable infrared scanner in 1973, the first dual-wavelength system capable of real-time analog recording for R&D markets in 1978, and the first uncooled infrared camera, the Agema 570, and 1997.
