I still have a Sony CD camera (as in disk not ccd) which has near IR and a IR led. Fun to play with for night recording (its intended use) and you can see though thin clothes a tiny bit but range is very limited. Skin patterns much less due to lacking contrast. Resolution in that mode is also lacking so detail is not really a thing. I can understand the problem and I think that is the reason my IR camera in my laptop has a moire pattern in the hardware to make it almost useless to the common eye. But that last part is just a guess.

Sony was forced to cripple the "night vision" feature of some cameras because it was too easy to abuse to see through clothing.
