Check ‘park’ I found the missing in that folder
i check its empty.
i had a similar issue. Innovv advised you check camera connections. Apparently the front camera controls the power once up and running, if that is loose it’s cuts power through vibration.
I hsd similar problems. Tightened up all cabling and no problem after.
If you have tried tightening the lens and the same situation still occurs, try the following.
The problem happens on DVR, that could be the vibration from the motorcycle makes the pin connection between SD card and SD card slot lost suddenly.
The soluiton is 1) fix DVR without movement, 2) like below photo, cut a piece of insulating tape to cover on SD card to reduce the gap between SD card and the slot.
What helped me is to hang the DVR in foam. This foam dampens the vibrations and so I have no more problems with writing the video files to the SD card.
There is now no chance that the insulation tape will remain in the DVR when you want to remove the SD card.
If insulation tape gets hot, it can come off.
