I am not sure about the camera interfaced with microcontroller....
but I have used a camera in one of my robot,
it was a RF wireless camera.
9 volt battery is required for camera & RF transmitter
and RF receiver should be connected to TV
There was no interfacing with microcontroller. Camera unit was working independently
But you can interface camera with microcontroller by controlling the 9 v supply given to camera.
This will allow you to turn the camera ON/OFF using microcontroller.
