I did a lot of experimenting with polarizers last summer and fall and while they can be useful I found that it wasn't worth all the trouble. As soon as the angle of reflection changes you've got a glare again and I often forgot to remove the filter at night which gave me poor exposures. Without a polarizer I am generally capturing the vital video imagery I need even if the footage isn't quite so attractive to look at. It is rare that a glare prevents me from capturing license plates and other important details.
I may experiment with some filters again but the fact is that most polarized lenses are not made to contend with constantly shifting reflection angles of light. There are some exotic polarized lens designs available that can better handle these conditions but they would cost more than the dash cams we wish to use them on.
Where do you find polarizers for a lens this small?
Do the normal and wide angle lenses have a different diameter?
Does anyone make a lens cover that has a clear glass or plastic cover to protect against dust especially in a car environment?
After looking at this camera I keep wondering why the heat sink is a chrome color instead of black. I assume the heat sink is aluminum. Black anodizing on the heat sink would cost little while allowing the camera to be hidden much better.
