Since you're familiar with the tech, you'll be aware that humans, who are alive, emit IR light which can be picked up by an IR camera, and a mask, which is not, does not.
- detaro 9y ago"IR" as in the heat coming of a human body is very different from "IR light" that is used in setups like this. Just like a cheap phone camera might be able to see the IR from a TV remote, but can't see body heat. And even if it could, heating a mask to body temperature isn't all that difficult.
