My almost 2 year old V3 has also developed an internal lens cataract. Since the camera is beyond warranty, I decided to disassemble it to see if there was any chance I could get the lens apart and clean it. The inside of the camera was spotless … absolutely no water intrusion. However, the lens is clearly damaged internally. My guess is that water has worked around the outer edge of the lens seal and gotten between the elements. Unfortunately there is no way to take apart and clean the lens assembly. It appears to have a threaded barrel which is probably adjusted to perfect the focus. It is then super glued into position. I’m guessing that Wyze does not replace out of warranty cameras. Has anyone found an exception to that?
