Car DVR currently has three storage methods: hard disk, U disk and SD card. Compared with the U disk (vehicle mounted U VCR), the reliability is higher.

1, the U disk has no mechanical moving parts and low power consumption. It can be used in all kinds of buses with rough traffic condition and bad power environment. In these cars, the hard disk VCR can not work normally.

2, the transcriptional data is convenient, directly inserts the U disk into the computer USB interface, can replay the video and save the video, without the hard disk connector, the USB adapter and so on, the operation is more simple.

3, U disk interface design is suitable for repeated plug and play, which is more reliable than SD card. SD card interface is the device interface, not suitable for frequent insertion, otherwise the damage rate is quite high. The USB interface is the interface between devices, which is designed to exchange data between devices. Whether the electrical, physical, or mechanical properties of the interface are suitable for the exchange of data between devices for a long time.
