In fact, 32g memory card is enough. Because the current dash cam basically defaults to the cycle recording mode. The logic of the recording mode is that the video captured by the dash cam is stored in the memory card for a certain period of time. When the memory card is full of storage space, the newly recorded video will directly cover the old video, so that there will not be the embarrassment of unable to record video due to the memory overload.
Due to the frequent occurrence of porcelain collision in recent years, many car owners choose to install dash cam in their cars in order to prevent porcelain collision. In fact, the dash cam can not only prevent people from touching porcelain, but also the video information on the dash cam is a strong evidence in case of vehicle accidents. Therefore, the installation of dash cam is really necessary.
At present, the car recorders on the market basically use memory cards to store information, but how much memory cards do we need to buy to meet the needs? Is 32g enough?
其实 32G 的内存卡以及完全够用了。因为目前的行车记录仪基本上默认的是循环录制的模式。该录制模式的逻辑是：将行车记录仪拍摄到的录像以一定的时长为一个片段，储存在内存卡中（片段时长 1 分钟、3 分钟、5 分钟、10 分钟不等）。当内存卡储存空间占满之后，新录制的视频就会直接将旧的视频覆盖（覆盖距离当前时间远的那段视频）。这样就不会出现因内存过满而无法再录制视频的窘况。同时也方面了我们，不用定期的格式化内存卡了。
In fact, a 32g memory card is enough. Because the current dash cam basically defaults to the cycle recording mode. The logic of the recording mode is: the video captured by the dash cam is stored in the memory card with a certain length of time (the length of the video is 1 minute, 3 minutes, 5 minutes and 10 minutes). When the memory card is full, the newly recorded video will directly cover the old video (covering the video far away from the current time). In this way, there will not be too much memory to record video. At the same time, we need not format the memory card regularly.
