Recently I designed a camera system based on a Raspberry Pi, to keep tabs on my workplace (100 foot high fire tower) I modified a HD3000 Lifecam to do this, and potted the circuit board into epoxy resin to keep it water proof. This mounting system was designed to attach to a magnet and allow a small amount of adjustment of the finished product, while remaining reasonably discreet. Photo attached. I'll also be uploading my adapter shims to fit a raspberry Pi into a Tupperware clone container.
