I’m sure I have seen this topic before, but a search did not find anything related.
A couple of my V2 cameras are now out of focus. Below are two screen captures from at the top the V2 camera I had pointed at my front door and at the bottom is the V2 that I replaced it with. You can see that the top image is clearly out of focus. At least one other V2 is also rather soft (but not this bad). Yes, the lenses are clean. Any solutions? Note that both of the out of focus cameras are old.
Also note that I have thought about a lens replacement (zoomed in), so this might be a good test case if it seems to be a lens issue.
