I think we all have seen the images of crime suspects, running in the dark of the night to escape the police, made with the help of infrared cameras. What can I do to be invisible to these cameras when I run from a bank I just robbed, through gardens, jumping over fences, but not running through long tunnels, or through woods with densely packed trees? When I run without having done anything (except robbing the bank) I show up on the screens connected to these cameras as a highlighted "blob" looking remotely human.
Should I wear a suit filled with ice, enclosing my entire body? Or would that also be visible, because in that case, I can imagine you see a dark human blob on the screen because the temperature of that suit is lower than my surroundings (unless it's a cold winter night, but let's assume it's a normal summer night or winter night if I lived on the southern hemisphere).
Should I wear a suit with excellent heat-isolation enclosing my body and which I've prepared in such a way that it has the same temperature as the air that night?
Keeping something (a big heat-isolating plate) above my head seems unpractical to me, and some parts of my body will certainly show up on the screen helicopter with the cops in it.
What else can I do to be invisible while still being able to run freely?
By the way, I'm not planning anything...
