A:AnswerI had a similar problem with the Kenwood dashcam. I think it was because the G-sensor is too sensitive that it takes every slight road bump as an accident and locks every video, even in the lowest sensitive setting. After the SD card is full of locked videos it will give you warnings that a locked video is overwritten by new videos. I ended up turning the G-sensor fully off and I have not heard that noise so far.
