I purchased this item to install on my late model minivan after having had a WinPlus backup camera (very similar) on my previous vehicle--so I have an idea of how these type of cameras perform in general. Ultimately, I chose this item over similar ones because I wanted something weatherproof and having a larger field of vision (more on that later). I don't really like the camera being included in the somewhat bulky license plate mounting bracket, but settled for that to get the other features that were more important to me. I actually prefer a smaller unit that can be mounted less conspicuously. If you install this unit on the top of the license plate it obscures the state name (in my state anyway) which is illegal, so I had to install on the bottom holes of the license plate. Also, in order to achieve an appropriate amount of downward angle on the camera/bracket so that you can see closer to your bumper, the use of the supplied angled shims and adjustments to the license plate mounting overall is clunky (the camera itself is not adjustable and cannot be tilted up or down independent of the entire bracket it is housed in).
This brings me to my biggest issue and that is the error in the product description--not just on Amazon, but everywhere on the internet it seems. The product description online claims 110 degrees of horizontal view which is superior to the typical 90 degrees of similar products. More expensive cameras can show 130 up to 170 degrees which would allow you to see almost everything on either side close to your bumper, but 110 is acceptable to me. This makes a big difference in what you can see from side-to-side, especially the closer you are to the camera (e.g. small kids or toys on the corners of you bumper). However, when the product arrived, the box and packaging clearly state that the horizontal view is only 80 degrees (vertical is 60 degrees)! So beware, you will not be seeing much on the sides as you get closer to your bumper--field of view is shaped like a pie piece, getting broader the further away from the camera you go. To me, it is most important to see things closer to your bumper which requires a larger field of view. This mediocre field of view was confirmed upon installation. If I could find a comparably priced system that was weatherproof (maybe this one isn't either if they were wrong about other things) and had a larger field of view I would buy that instead of this one. Very disappointed in the erroneous product description which led me to purchase a product that I might not have otherwise.
The installation went ok...pretty much as described though I could not get the inline wire connectors to work and had to hardwire it into the driver's side backup light socket. Once installed, the camera functions reasonably well. With all wireless cameras, you will get some occasional flicker/static--more depending on whether you are near other 2.4ghz wireless interference (e.g. wifi internet connections). It works according to specs and does an adequate job, even in low light with the included night vision (notice the tiny infrared 'bulbs' on either side of the camera lens). Would be nice if the included LCD monitor was a little larger than 2.5 inches. My previous unit had a 3.5 inch monitor which was noticeably larger and easier to view. Overall, this is a pretty average unit compared to similarly-priced options. Don't know that you will do much better unless you spend more.
Positives: Inexpensive, works, weatherproof (or is it?)
Suggested improvements: Improve the field of vision and put the camera and transmitter in a smaller form factor that can be more easily mounted in other locations besides the license plate. Include a larger LCD monitor.
