->  RJT> Not as elegant as an IR camera,  but one hell of a lot cheaper!   :-)

-> I think most electronic cameras are sensitive to IR to some extent...
-> (with the lights off of course) since to a CCD a photon of any colour is
-> still a photon. I think a cheap alternative may be those simple camera
-> modules used to wire into a circuit.

 As I recall one of the Sony Consumer Market Digital Cameras has an
Infra Red capability.
