Here are some videos that actually use thermal imaging cameras for some scenes or even for recording the whole thing to give you a better idea on what kind of images thermal cameras produce. Mind you these videos rely on much higher-end thermal cameras than the affordable consumer options I have covered above, so they are capable of recording high framerate videos with a significantly higher thermal resolution…
