Installed Furrion Wireless System - All I Can Say is WOW!

I have had the Furrion observation system now for 3 years and this year, actually the last trip a few weeks back I noticed a definite drop in video quality. Its been great up until now. I have not had time to pull the camera and look into it but I know its not dirt as I pulled over and cleaned it with a lens wipe. Its almost like either the lens is now scratched somehow, or moisture has gotten inside the camera. Ill post back once I figure it out.
