The loop recording of each driving recorder has an on and off setting. Check whether your dash cam has been turned on and set the time of the loop recording.

The speed of reading and writing the memory card of the driving recorder is slow, which may result in the inability to record continuously. It is necessary to ensure that the memory card is a genuine card, and a Class 10 Micro SD card with a faster card speed can be considered.

If the crash video clip of the dash cam disappears, it may be that the dash cam is powered off during the collision, causing the crash video clip to disappear. It may also be that the driving recorder is stuttering or lag, and there is a loss of recording. In addition, it may also be a problem with the settings of the dash camera itself. When the car collision, the locked video of some dash cams will be renamed and saved, making it difficult to find.

If the motion detection function is turned on while driving, it may also cause the video to not be covered, so you can choose to turn off the motion detection when you driving.

The loop recording time setting should not be too short. If it is too short, the video files will be broken and the service life of the memory card will be shortened. If the time setting is too long, it may be troublesome to find the accident footage, so it is generally recommended that you set it to 3 minutes or 5 minutes.
