In view of the strong vibration of the car, the hard disk video recorder must be installed with special shock-absorbing rubber gaskets in the fixed position of the hard disk bracket and the car body, which can better reduce the damage to the hard disk caused by the car vibration. The main board of the hard disk video recorder should also adopt an integrated single board, which can avoid the problem of loose connection of multiple boards due to vibration. It is recommended to buy a dedicated car hard disk video recorder, and the storage medium is best to choose an electronic hard disk for recording, which can effectively avoid data loss caused by vibration.
