I have this cam model (https://www.sparkfun.com/products/14028) and I need put this on peep hole. This cam model can't fit the peephole I have on the door. My idea is film through a tube (+/-) 10mm in diameter and 50mm long. I plan to film whoever is at the door through the peep holes. Is there a lens for the raspberry pi that's long enough to fit into the door?
I found this articles but I can't find any type of the lens equal or fit the cam to mine peep hole:
