His camera captured fraud (4)
I believe the answer is:
scam
'fraud' is the definition.
(scam is a kind of fraud)
'his camera captured' is the wordplay.
'captured' indicates the answer is hidden within the clue.
'SCAM' is hidden within 'his camera'.
(Other definitions for scam that I've seen before include "Fraudulent scheme, swindle" , "An informal swindle" , "Fraudulent action" , "Dodgy business" , "Con trick" .)
