I'm a little stuck... Click here to teach me more about this clue!

'secretly' is the definition.
(I've seen this before)

I cannot understand how the rest of the clue works.

(Other definitions for in camera that I've seen before include "Kept private (law)" , "It's not open court" , "In private court" , "(Held) in private" , "as films these days are less often seen" .)

I've seen this clue in The Telegraph.
