Just a quick note. We had problems with a cloudy rear vision picture from a Polaris 'Type C' Rear Vision Camera.
Problem was caused by moisture getting in to the camera, clouding the lens and corroding the internal printed circuit boards.
Contacted the supplier, Poron Aust Pty Ltd at Rydalmere. The Poron rep, Naomi, understood the problem I was having immediately and sent me a warranty replacement camera very promptly and without hesitation.
Fantastic service and new camera working great!
