This was easily the least cost combo backup/rear-View Camera with sensors I could find on the internet. I purchased it for ease of install and use. While it did take me about 3 hours to install, that was a function of the plastic clips on my Venza hatch. The actual install is very simple. Just hook up two power wires to your backup light wires and run the long s-video like wire to the dash and plug into the monitor. Yes the monitor is tiny at 2.5 inches, but good enough to see if there is anything in the way and works just fine in the dark, except for some glare if there are lights shining from behind the car from another source. The sensors beep slowly from about a 4 foot distance to an obstacle and sounds continuously at about 3 feet, so it works as promised when there is a solid object, or just a pole, behind the car. If you are beside n object, it gives a much shorter range of warning, only about a foot or two, depending on the severity of the angle. Overall I can't imagine a simpler solution, unless you are willing to spend more than twice as much to get the video and range detection.
