I understand sentry is to record when parking and dashcam when moving, but it seems dash cam for me also record when car is parking. What's the difference then???? I have sentry mode off but still see all the clips recorded at usb drive.
Dashcam and Sentry mode (if turned on) recordings are stored in the same place, the external USB drive you added. If you are viewing them in the car, you can filter to only show you either category.
