Question: How is it wireless if everything seems to be wired?
Document: A big plus that made installation much easier.The camera I wired into the backup lights in my Camry trunk. I cut  the maze of wires and spliced the shortened cut ends together. Thus I got away with a small hole in the trunk lid to pass the wire through.The monitor and wireless receiver:  I powered these with a cigarette lighter power outlet from Radio Shack.
Parts were not cvompatible and as a result I could not use. I attempted to resolve installation issues buy purchasing additional parts to make everything compatible, they did not work. Junk.
This Wireless back up camera and  monitor works real well. I just wish it didn't have the distance lines on the screen all the time.
This item is very versatile. It has good wireless range and good quality picture. of course, it IS a reverse camera, so the image displays backward in the monitor. A minor inconvenience if it really keeps me out of an accident. Great price for what it does!
I got these in 2 boxes. They are not one single package. The wireless is total waste of time. Forget about the instructions. You need an electrical engineer to decipher the instructions. It is wasted of money, particularly the wireless part of the items.
The Taotronics rearview camera system is really great. The clarity and color are exceptional and much better than I expected for such a low price and the guide and distance markers are very helpful. The 4.3 inch screen is just right for viewing and small enough to be conveniently positioned in my Camry. The wireless system is an easy installation once you get over some basic obstacles (the connectors on the camera wires need a larger opening to get through to the trunk).
I have 2005 Toyota Van, I have installed a backup camera long time ago and lately found this one even better.I ordered this a few weeks ago, I have some wireless issue when I received the product but seller was take care it ad replaced it in a very professional way. very nice and also provide me technical help.I will recomment this product and this seller to any one who are looking for a backup carema.
To mount closer to the center of the veichle cause the license plate is on the left side of the van and wouldnt show the right side of the van very well so what I did is cut 1 inch off both sides of the camera bracket and drilled two new 1/4inch holes then drilled two 1/4inch holes into the plastic trim peice the holds the licenses plate lights then ran the wire to the reverse lights like I did with the monitor.No problems with wireless transmitter or receiver  two thumbs up.
this was better than I expected for the money. The color is great and it has a clear picture and good angle of view.
so that I can remove the monitor if I need to clean the window.I read some reviews about interference, but I am not getting anything like that. And you can clearly see what you are backing into at dark. This IR camera works great!Monitor is normally off and it comes on automatically when you put on a revese (when reverse lights comes on).Great price for great product.
Answer: The camera is wired to the back-up lights, and the monitor is wired to any power source that is convenient such as the fuse block, or even a cigar lighter.  THe camera sends the signal to the monitor wirelessly.  However, if you can run a wire easily from the backup lights forward to the monitor, the monitor will be powered only when you are backing up, (when you want it to be)  rather than be powered continuously.
