@rrands One of my black v2 cams did the same thing a while back. I had to take the cam apart and clean the small round glass, problem solved. I’m guessing your v2 is having the same problem.

See this thread and long discussion on foggy images.

I took one apart to get to the bottom of this and to my surprise, I found a very scuzzy little piece of glass under the lens of the camera but over the sensor. I cleaned it off and the difference has been pretty drastic. I’ll try to fix another camera and get some before and after photos. Can anyone explain the purpose of this little piece of glass? UV filter? And do you mess anything up by cleaning it…
