I didn't know they could see through walls in the first place.

Right. TI just reads heat. If the wall is cool, it'll appear as dark on the output.

You've lost me.

Yes, a bit of canvas is much more heat permeable than a concrete wall.

Most glass you will find will block the Long range IR wavelengths (that's just how it's made anymore) and if you place a pane of glass between you and that system you won't see through it.

I see what you were saying. I thought you were saying that even if the glass is warm you won't see the heat on it.

And I think that they have shortwave FLIRs already on the market that allow you to see filaments inside light bulbs, for example. Pretty cool.

this is why i prefer Backscatter X-ray technology and Millimeter wave radar for all my "seeing through walls" needs.
