Circular Polarizing ( CPL ) filter mainly used on dashcams to help to reduce dashboard glare.

Depending on the angle of outside light source ( sun in day time or street lights at night ) which reflects from car dashboard, in many cases dashcamera may record quite heavy dashboard glare which may block partially recorded footage. In those cases CPL filter may reduce this glare.

Below are screenshot comparison of side by side Street Guardian SG9665GC With and Without CPL filter.

Top is without CPL, Bottom is with CPL

CPL filter shell made of strong and flexible plastic with heatproof rating up to 80C / 176F.
Made In Germany CPL glass consist of 4 layers: protective glass + Circular Polarized glass + protective glass + UV glass.
NB! CPL glass comes already manually pre-adjusted for correct polarization.
Buyers don't need to adjust anything, - just attach to SG9665GC

Very easy to attach / detach. Stays firmly attached in place and can withstand strong shaking ( road bumps / potholes )

thanks for putting this together, I know it has taken a few days work already

edit (moved post)
No problem. There are more to come. Videos and screenshots from different scenes. Processing-editing-synchronizing takes ages. I wish I could have a "Tianhe-2". OK, I am even fine with "Tianhe-1" ;)

More than my wife thinks I need.
Looks good!! ThumbsUp.jpg

Lens material is a lighter color than what I used for my DIY version so there should be less light loss. Will be ordering as soon as available.

yeah if you have a look at the night results it works quite well, I think it's a good balance between performance and glare reduction, a heavier filter might have cut more glare but then become unworkable in a lot of situations

Does the circular lens rotate?

Edit: Ok, next time I'll read the whole lot first. ;)
