Answer 1

many cops military forces use this technology.the camera picks up thermal radiation from anything.believe it or not humans give off thermal radiation.the camera picks it up.that device is used to see in difficulty at night.somewhere that is difficult for humans to see.or in another words info red light.

Answer 2

I remember some military videos featuring thermal cams where they can see the bodies of soldiers within buildings. It will depend on the material and thickness of the walls (technically materials with better heat conductivity such as metals will offer more transparency).

EDIT: Opps, it appears that the answer is no. http://www.prtech-thermalimaging.com/pro...
