Corrected entry: The art gallery is conveniently fitted with heat sensitive cameras. However, this would not be sensible in an art gallery, as infra-rad cameras cannot make distinctions such as precise facial features, necessary for identifying a thief.

Correction: They would however be capable of detecting the presence of a human being and setting off the alarm. Even most regular security video cameras give fairly poor images and are not much use for identifying people unless they look right at it for a few seconds.
