How does a thermal imaging camera work?

Even in complete darkness, all objects emit thermal radiation. Thermal radiation is light in the long-wave infrared range, which is invisible to the human eye. It is precisely this long-wave infrared radiation that a thermal imaging camera uses to generate an image.

Hi, I'm doing a presentation on thermal imaging camera's use in the movies. Do you know any movies where they shot scenes with one? Thank you very much!
