What is a CPL filter?Updated a year ago

We have a page dedicated to this inquiry that you can find on our What is a CPL Filter guide.

A CPL (circular polarizing lens) filter is a lens that you can put over your existing dash cam lens to reduce glare and reflection, which in turn improves video quality.

Vehicles with dashboards that have shiny or light-colored plastic tend to suffer from the most reflections which can be distracting and make details like license plates and vehicle makes/models harder to pick up - this issue is actually quite prevalent for many vehicles.
