I have asked the topic title question to the Blackvue support, but didn't really get an answer... What does the setting do really? I have my car parked in a garage for the day, and it is almost constantly recording video for even the smallest movements - e.g. a person walking by all the way to the other side of the parking garage. I have put the setting to 1 (very low), but nothing changes. Anyone any idea how I can make the camera less sensitive?
