His camera captures swindle (4)
I believe the answer is:
scam
'swindle' is the definition.
(I know that swindle can be written as scam)
'his camera captures' is the wordplay.
'captures' indicates a hidden word (the answer is trapped within the clue).
'SCAM' can be found hidden inside 'his camera'.
(Other definitions for scam that I've seen before include "Racket" , "Fraud, dishonest scheme" , "A modern kind of swindle" , "Screw" , "Swindle, fraud (colloq.)" .)
