It would be pretty handy to have a black box for your car, just like airplanes have. That way if you got into an accident, saw a crime being committed or got beaten up by a cop for no good reason, you would have a record of the event.
That’s basically what the Car Cam Voyager does. It acts like a black box. It’s the first video camera for the car that allows you to record what is happening in real time while you’re driving. The device can display captured video on the 2-inch 320×240 screen and can record up to 48 hours of video on the road to a 32GB microSD card.
