Did you know the current thermal images are based on technology that was originally developed for the military? On Feb. 11, 1800, astronomer Sir William Herschel was searching for optical filter material to reduce the brightness of the sun’s image in telescopes during solar observation. The first heat-picture became possible in 1840, the result of work by Sir John Herschel. The growth of thermal in the security industry is only in its infancy stages. With the need and desire to improve video surveillance and the ever-increasing application for the system analytics, thermal is here to stay.
