In this day and age, it's a really good idea to have one of these in every car. Recently I saw on FB that a motorcycle stopped in front of a car and the driver threw himself onto the hood of the car pretending to be hit. Luckily the driver of the car had one of these cameras and shouted to the motorcycleist that he had been caught on video. The motorcyclist took off immediately! There are a lot of shady people out there now and one of these can be invaluable. It is easy enough to hook up, but the instructions are very hard to understand and I'm not sure how to do a lot of things on the camera, but I have it working and recording in a 5 minute loop. You will need to purchase a mini SD card to be able to record or use this camera. It has a good, clear picture and does a good job. Good enough for the price.
