Nope. IR reads surface temperatures only. It just doesn’t “see through walls,” I don’t care how many movies there are in which Arnie has to fight a guy looking through walls with an IR scope. They don’t exist. Not ones that look thru walls.
Tech to look through walls may exist, but it’s not IR.
I can make deductions about what’s going on inside a wall, for instance if part of the wall is wet or poorly insulated, but that’s because these conditions change the surface temperature in those areas.
IR will see through smoke and fog quite well. Most plastic materials are transparent or translucent to it, even heavy black plastic. But most types of glass are a mirror.
The above all applies to the IR spectrum most often used in cameras. Other parts of the spectrum might work somewhat different.
Millimeter wave camera sees through plywood (sort of):

Maybe a more advanced version might work on the Wells Fargo building ... where are the guards? where is the money? where is the twit with the PA microphone? Gotta take her out first! Oceans 14?
