Firefighters sometimes have to face extreme temperatures while on the job. Luckily, they can rely on thermal imaging cameras (TIC) to find victims faster or to seek their way out of a building in such circumstances. In an attempt to choose equipment with the best specifications, firefighters sometimes go for cameras that are able to display very high temperature ranges, up to +1,100°C (+2,000ºF), in a so-called third-gain mode. This is not a good idea. In fact, there are very good
reasons why some thermal imaging cameras do not have a third gain mode, and only measure up to +650°C (+1,202ºF).
