This depends on the user manual of the driving recorder: what kind of card can be equipped, how large the card can be are all explained in there. As long as the size does not exceed the carrying capacity of the equipment, you can choose according to your actual situation.
However, if you want to save the entire video on a self-driving tour, it would be a problem if the capacity is too small. Even the loop video can only save about one and a half hours of video. Once a traffic accident requires evidence collection, there may be data loss. So, try to buy a memory card with a larger memory.
Due to the complicated driving conditions of many car owners, the jitter can easily cause the recorder to be too hot, unable to store, unable to record, crash and black screen, and may even burn the driving recorder directly. It is said that the smaller the capacity, the easier it is to break.
As long as you drive, the memory card will be written and erased continuously, while the number of erasing and writing of a consumer-level memory card is only 300, frequent card replacement has become a headache for many drivers. In addition, consumer-grade memory cards do not have a life reminder function, and car owners have no idea when their card should be replaced, and once the number of erasing and writing is used up, data loss is extremely likely to occur. In addition, bad weather can easily cause damage to the memory card, so it is particularly important to ensure the quality when purchasing a memory card.
