An adapter is absolutely feasible and would be easy money for wyze. I’ve found some resources and it looks like a DIY solution is completely doable. I’ve ordered another v3 and a 25mm M12 lens. The zoom lens should allow the v3 to look through an already installed peephole normally. I’ll update this thread with my results. Will just require a little disassembly and setting the focus correctly.
As for the cord it’s not hard to just run an extension. Not the cleanest solution. A longer thin USB cable would probably look better.
