I have had a Panasonic BL-C131A IP Camera a long time ago. For a while, it was on a window sill aiming outside. It worked like that for years. However, one day I noticed that it appeared to be slightly out of focus. It took a while to figure out, but the lens appears to have been damaged. I used a microscope to look at it and am surprised it works at all since there are areas that are clearly pitted. I will guess that something reflected direct sunlight into it and caused the plastic lens to melt. The camera works perfectly except for the lens damage. (ie, ethernet, wi-fi, internal processor, pan, tilt, microphone, etc. all work). I hate to throw away things that still have value, but repair parts don't seem to be available anymore. If only I could somehow replace the lens, I would still have a good camera. But, the lens in tiny - approx 1 mm in diameter and buried inside layers of boards and plastic parts. Unless anyone has any good ideas, I guess I will just throw the whole thing in the trash.
