The package includes 2 CPL Polarising Lenses, front and rear. Using the CPL (Circular Polarising Lens) filter on a dashcam can have several benefits. It can reduce reflections and glare from the windscreen and other surfaces, resulting in clearer and more accurate footage. This can be particularly useful in bright sunlight or when driving near water or other reflective surfaces. In addition, a CPL filter can improve color saturation and contrast, making footage more vivid and detailed.

After much analysis, we found that most of the problems of the dash cam are caused by the memory card because the speed and number of erase and write of the memory card cannot meet the requirements. Therefore, the package comes with a free 128GB V30 speed memory card, 1500 times erase and write, this memory card has been tested many times, especially for the 4 FHD cameras dash cam. It is more durable than the high-end memory cards on the market, which can make the D80-4CH-MINI car dash cam more stable and reliable, and work continuously for a long time. We therefore recommend that you use the supplied memory card.

*If you want to use the parking monitor function, please search for B0CGXK823B and purchase our mini USB ACC hard wire kit separately.
