Hi Tommy,
1:
If there are no incidents, the videos are not recorded in the accident folder. Depending on the G-sensor sensitivity setting, the videos are saved in the accident folder.
You have to find the correct G-sensor setting through trial and error. Set the G-sensor to the most sensitive setting. Go for a ride and check the recordings. Set the G-sensor to a slightly lower sensitivity and check the recordings. Reduce the G-sensor sensitivity until no recordings appear in the accident folder during a normal ride.

You can only delete protected files by formatting the SD card using the Innovv app. Please note that this will delete all recordings, including those in all other folders.
You can also insert the SD card into your computer and then empty the accident folder. This is not recommended, as the Innovv camera may then no longer be able to handle the SD card properly.
