Appears to be a decent setup. Read all the specs. & options on it. It comes with one camera, but can be expanded to two, for extra $. Several other camera mounts are also available, aside from the license plate frame mount. Instructions indicate you can hot wire it to the ignition system or the reverse backup light circuit. Another option to that, is to connect to your headlight system, the camera would be on when the headlights are on only, rather than the ignition system method that has the camera on constantly, which I deam unnecessary & can still be used during daylight hours if you wish, like seeing behind the rig driving down the highway.
