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 a hidden word.
'SCAM' can be found hidden inside 'his camera'.
(Other definitions for scam that I've seen before include "Fraudulent scheme, swindle" , "An informal swindle" , "Fraudulent action" , "Dodgy business" , "Con trick" .)
