I slept at Holiday Inn last night. Infrared cameras work by sensing infrared energy (heat.) Since heat is transferred from molecule to molecule within an object - there is no definitive "line" of energy difference to be detected - objects appears blurry because there is typically a gradient of heat difference across the surface being observed. This is unlike a visible light camera - which detects the minute details of color differences in clothing, objects, flesh, etc.
