First, its Infrared camera, not inferred camera.  Secondarly, no.  The
camera you are talking about is basicaly a simple black n' white camera
which is sensitive down to part of the infrared wavelengths as well as the
visible.  This camera is basically useless for applications such as thermal
imaging.  

A true infrared camera, such as those made by FLIR systems (www.flir-dot-com),
is sensitive only in the infrared range (or will even combine both visible
and infrared range into one image).   These type of cameras also divide (can
be custom set) a preset temperature range (say 0degC to 100degC) into some
type of color scheme.  For example 0-10degC might be bluish, 10-20degC might
be green, 50deg orange, 60deg red, up to 100deg which is white etc....

Here are some sample images from my Solid State Tesla Coil.  You can see
some diodes and resistors on the board which are very hot compared to the
other components:

You can pick up an inferred camera for abut $39. from most of the
electronics parts houses. Its a single chip camera mounted on a small PC
board, about 3/4" square.
I've used these and they work great. They can see a hot clothes iron in the
dark, or the flash of a remote control.
