After much analysis, we have 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 D90-4CH dash cam, which has 4 FHD lenses. It is more durable than the high-end memory cards on the market, which can make the D90-4CH car dash cam more stable, reliable and work continuously for a long time. Therefore, we recommend you to use the memory card provided by us.
