Used camera was: https://www.amazon.com/SainSmart-Fish-Eye-Camera-Raspberry-Arduino/dp/B00N1YJKFS
(For an alternative mount for bigger cam modules see here)
You will need a dreml to slit the case to allow the flat flex to pass through and a 14mm drill
Note that you can remove the whole insert to make drilling and assembly easier.
- Mount cam in insert
- Mount insert in mount
