I saw one of these on the dash of a MINI at a recent MINIACS Only car meet at Tintern Abbey. Aaron Ewers who had the camera was very helpful and explained how it works.
Bottom line I ordered one. A tenner from EBay and to be fair it’s a lot of kit for a tenner. The video is good quality though sound if you choose to use it is a bit scratchy. Video recording starts when you switch on and stops when you turn off. It makes short recordings the length of which you can determine, sat three or five minutes and immediately records another once the first is done, until you switch off. Should you have an incident you need the film for then it will be in a smaller more managable clip.
Put simply then, I’m very pleased with this.
