don't get me wrong like the way you build it

you can take the cam apart so you have only the inner parts.so it's much smaller.
like this guy is doing
http://www.ugolog.com/pages/build-a-spy-camera
he is building it in a fake charger. but you can make it in the inside of the cap.
with a hole for the cam lens.

if it's possible.
to make that kind of system.
