Rear cameras are used much like a rearview mirror except the operator can get a very wide view of the entire area behind the truck in a single glance. Available in a range of lens angles, rear cameras can provide a wide angle view for general safety when backing or with the correct mounting these cameras can also be used for very precise backing in tight quarters, allowing the operator a view into the blind spot directly behind the truck. A magnetic base makes for a quick and secure mounting that can easily be changed if required.
