I have 7 RING cameras. 3 are wired and 4 are wireless. Right now all 4 wireless cameras are fogged over. The 3 wired cameras are nice and clear. I believe the wired ones must generate some heat which keeps them from fogging?
Well I've got a wired door bell and it mists over so don't that is the case with door bell son got wireless and his mists over as well
