XIQIRear View Backup Camera System, 7" Digital Wireless Split LCD Monitor with Two Wireless Waterproof Ir Color Cameras for Excavator, Cement Truck, Farm Tractor, Trailer, 5th Wheel, Rv Camper, Heavy Truck

I just installed one camera on my 5th wheel trailer 33 feet long. It seems to work good but it did flicker while moving around my yard. I purchased the 12 volt 2.1mm cigarette lighter plug from Amazon which works good on this unit. It just plugs into the wire harness and then into the lighter plugin . It was simple to wire the camera into my clearance lights on my trailer. It has the adaptors needed to wire into your RV. Directions are not to good.Wire red to positive and black to negative. Clearance wires will be the same color. Check wires with voltage meter.Update. I have driven about 600 miles with one camera mounted on my 5th wheel. The total distance from monitor to camera is about 55ft. It does loose signal at times but the picture is good and it will work for what I am using it for. I plan on pulling a trailer behind my 5th wheel so this will let we see what is going on . When I am backing my 5th wheel this allows me to see what is behind and shows the distance I am from any objects. Update, monitor stopped working at 10 months old. I was able to get a new replacement for a $15.00 shipping fee.

OK,. once again I order something on Amazon based on the description and again the seller misleads with incorrect description of what they are selling.  Rear View Backup Camera System, 7" Digital Wireless Split LCD Monitor with Two Wireless Waterproof Ir Color Cameras for Excavator, Cement Truck, Farm Tractor, Trailer, 5th Wheel, Rv Camper, Heavy Truck . The 2 cameras are listed as "Digital Wireless Waterproof IR Camera (MODEL:DF-8275H-SFSx2) Image Type: 1/3 inch Color CMOS Horizontal Resolution:500 TV Lines Effective pixel:NTSC:720(H)X480(V) " They are not!!! What comes is Model DF-8275SFS (missing the H in the model number) cameras which have the smaller 1/4 CMOS and the resolution is less at Horizontal Resolution:420 TV Lines Effective pixel:NTSC 640H x 480V. What you get is crappy cameras! Not what's advertised in the description.Update: Installed the system and the picture is OK but low resolution. My motorhome is 27' with a fiberglass body, I'm happy to say the image stays constant. No issue with loss of signal or flickering. The build quality is good, everything is solid and the power connectors are good (plug and twist connectors). I'm giving this 3 stars because the signal strength is very good but the picture resolution is low but adequate.

Installed this camera over a year ago on a 30' motor home and it has been working perfectly ever since. The two cameras are perfect to provide a bumper view as well as an up high view due to the extra height of a motorhome. The two cameras were wired to the driving lights for power so they are always on when the lights are on and that was easily pulled from the taillights and ICC lights. The monitor installed easily on the dash and is wired to an accessory circuit for continuous use since a rearview mirror isn't that useful in a 30' camper so these are used all the time to see behind when driving. Wirless on them has been working flawlessly as well.

I had a problem with one of the two cameras which in my opinion could have been easily resolved. However the manufacturer did not respond to emails and could not be reached by phone.

I purchased this camera system in November 2015. Installation went smooth, and the monitor had good color. Two weeks ago the monitor is showing green grass & green leaves on trees to be purple. I have contacted the seller and currently waiting their response. Hopefully they will replace it under the warranty. Only time will tell.

Awesome product and awesome service. I installed 2 wireless cameras on the rear of our 40' motor home. Just supply power to the cameras and monitor and everything works perfect out of the box.

I just got it installed today in my John Deere tow behind seed tank, one at the back to view traffic behind and one inside the plastic tank, wasn't sure if it would connect to the monitor, it did and the picture was real good from both cameras. Will be good to use this year.

Great camera video set up. Picture is clear and switching between the 2 cameras is easy. I like the split screen view and the guideline view is handy.
