This clue might be a double definition.

'private' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.

'room taken on vacation' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?

Can you help me to learn more?

(Other definitions for camera that I've seen before include "Photo-taker" , "Brownie possibly" , "Source of pictures" , "A court held in it is not open to the public" , "One never lies" .)
