I purchase the basic Furrion 5" single camera wireless about 6 years ago on Amazon. (paid about $400 back then)
It was great. started to get really foggy video recently.
I just got a new trailer and when I transferred the camera from old trailer, I polished the lens and was amazed how it looks like brand new unit. Video is now crystal clear.
I used one of the headlight polish kits with attachment for drill. 800 grit to start, 1500 and then polish. I had this already for a car that needed headlight restoration.
$17.00 on Amazon.
