As fans of 1985's "Witness" will remember, John Book goes to great lengths to protect the Amish child turned star witness in a murder case. It stands to r­eason that he'd work to ensure the safety of other children in our make-believe "Witness" sequel, which is why John Book will just love our next car gadget: back-up parking cameras. According to safety advocacy group Kids and Cars, two children are killed and 48 children are seriously injured every week because a driver that was backing up didn't see them [source: Consumer Reports]. It's not that these drivers are lazy or bad people, it's just that there's a blind spot when a car is reversing that's perfect for unknowing children to play in.

Enter back-up parking cameras. These cameras send live images of what's behind the car to a screen on the dashboard; the image comes up as soon as the driver puts it into reverse. And even if no children, pets or bad guys are hiding behind your vehicle, it still provides a handy way to parallel park perfectly or to back your vehicle up to a trailer hitch. This is a gadget that comes ready-installed in some vehicles, but wireless and wired versions are available as well.
