What is a Circular Polarizing Lens (CPL) Filter?
A CPL (circular polarizing lens) filter is a lens that you can improve your dash cam video quality by reducing lens flares, glare, and reflection that significantly impact the quality of footage details, like license plates and vehicle models. Eliminate these issues caused by moments of extreme brightness by quickly installing the Vantrue’s Circular Polarizing (CPL) Filter. Then you can reduce glare and increase the quality of your E1 or E2 dash cam footage.
These filters work best when outdoor lighting conditions are at their worst. For example, the sun rises, causing the dashboard to reflect on the inside of the windshield. Polarizing filters can also help reduce glare when facing the sun directly. Check out our comparison footage below, showing the same scene with and without the filter on the dashboard.
