Review on PARKVISION Mini Car Side View Camera/Rear View Camera/Front View Camera: 360° Rotatable Lens, Easy Installation Without Drilling, Upside Down Flip Image function - No Guidelines [S142] by John May

I had a problem and found a solution with this and several other products. We have an RV with 5 wheels and I wanted to be able to line it up when connecting the 5th wheel to the 5th wheel. Trailer hitch. With the rear seats up in our 2004 Chevy Silverado Crew Cab, I can't see the hitch and wanted to fix it. Yes you can use these magnetic tennis balls on folding poles and I have used them but they actually work better with our trailer when attached to this RV. I shopped at Revain and recognized a small camera on a small screen as the large rear camera could easily see the pin box on the fifth wheel wheel and hitch on the back of the truck. I bought this product and also got a '4.3' foldable monitor from E-Kylin, all from Revain sellers.As shown in the photos, I installed the camera under a high mounted taillight on the cab of the truck, I used a round file and made a hole under the light for the wire so it wouldn't break.I then routed the wiring down the cab and up to the front instrument panel.With a small foldable monitor,an additional red one and black wires and a 12 volt power supply. I connected the camera and the supplied monitor power plug to the power plug, the red power plug and yellow video plug go to the foldable monitor. and connection. If the RV is plugged in, turn it off , fold down the monitor and you're good to go until next time.Only 4 stars because the instructions are included in the very nice packaging, but of course they are rlich is a bit vague and the functions do not work as stated in the instructions. I was able to easily work around this and get it working to my satisfaction. A tip: There is a white reference line on the camera. I didn't notice it at all until I mounted and installed the camera with its strong double-sided tape. When trying to flip the camera view since it was upside down at first, I manually rotated the camera on the camera base until the video was properly set. Then I saw the tick! The line is done! When needed the video quality is fine and the whole project took a couple of hours and about forty dollars for all the necessary parts. At the moment the problem is solved.
