A dash cam or dash camera is a little digital video camera mounted in the windshield of the vehicle to record all that’s happening in front and sometimes at the back of the driver. It comes in handy when you encounter a road accident or in case some Youtube-worthy events happen. Think of them as GoPros on your car.
There are two basic types of dash cams available today- single lens and dual lens. Single lens models are fitted to the front windscreen and records videos from the front of the vehicle. Dual lens models, on the hand, have two lenses to record the front and rear of your car.
