CPL Filter for Street Guardian SGGCX2PRO, SG9663DC, SG9663DCPRO, SGGCX2, SG9665GC V3

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.
