Is a CPL filter worth adding on?

A CPL, or Circular Polarizing Lens filter, is one of the simplest yet most effective upgrades you can add to your dashcam. Think of it as a pair of sunglasses for your camera — it fits neatly over the lens and works to cut down glare and reflections from your windscreen and dashboard. The result is footage that looks clearer, sharper, and far more natural, especially when driving on bright, sunny days.

The way it works is straightforward but powerful. A CPL filter selectively blocks reflected light, particularly the horizontal glare that often bounces off dashboards, car interiors, and wet roads. By allowing only direct light to reach the camera’s sensor, it eliminates those distracting reflections that can obscure details. This enhances overall image contrast, deepens colours, and brings out crisp detail in the sky, road, and surrounding vehicles.

Whether you’re using your dashcam for daily driving or capturing scenic road trips, a CPL filter makes every recording look cleaner and more professional. It’s a small accessory that delivers a big improvement in video quality — ensuring your dashcam captures every moment as clearly as you see it through your own eyes.
