Question: where can i get this professionally installed?
Document: Am excited but have not installed the backup system as yetdo plan to do so in the near future. Looking forward to beingable to see behind me in the big rig. Score only out of the box.
I agree with the other reviewers that this is a great value. The screen is nice and big. The mounting bracket is really articulate and you can position it just about anywhere. The buttons are easy to get to. The menu is easy to navigate. The installation directions are sparse but adequate. I am a journeyman plumber so I might have more mechanical inclination that the average bear.Be patient with the installation.
This is a professional unit for a commercial vehicle. Don't get it if you want a sleek unit that won't stick out much. Do get it if you want a reliable setup with a great picture from a company that will answer your questions in good English.I would have given it 5 starts, but the camera in one of the mounts is crooked. The camera works great, but it's mounted crooked inside the cover.
I have a small one man cattle operation. Feeding with a hydra bed bale handler and bulk cube feeder. Due to my job I don't get to feed until 7:00pm its dark! Not being able to see well and having the cube feeder blocking my view I'm always worried about backing over a calf. Backing up to trailers is time consuming because you are getting out of the cab and walking to the back to see if you can hook up to the trailer.
The detail and clarity night or day is exceptional!I mounted my camera on strong magnets so I can move it to the head-ach rack when I take the feeder off this spring. Camera angle is not the best at this time but will improve when I get it mounted higher. Install was simple, BUT the monitor mount is very weak in my opinion. The screen size is very nice, but being so big I feel it creates a dangerous blind spot if mounted on the dash.
We installed this setup on out New Holland TN75 to help keep an eye on the manure spreader, baler, cutter, and bale wagon. So far it's working very well. It saves your neck and has a very bright screen. It makes it much easier to keep an eye on what's going on behind you since you can't hear in the cab with the AC and radio on. Good night vision as well.
Arrived on time as promised. Installed one camera behind my truck as a rear view mirror. The second camera is on my boat trailer for a 22 foot pontoon. I can now safely change lanes on the express way without worrying about cutting some one off. The camera and all parts are made of high quality material. Would highly recommend tis to any one as I did to my younger brother who owns a camper with a fifth wheel.
It worked great! Then I checked for voltage, ground and continuity from inside the multiplexer to inside the monitor. I tested each wire until I discovered that there was no 12 volts to the board. This troubleshooting was done knowing that I invalidated my warrantee and any chance of returning the unit as I had to take the monitor and multiplexer units apart to check continuity of each wire. It was an easy decision based on the fact that I had already installed the rear camera and the 65 feet of cabling.
Why not make the second camera a side view from the start?
We purchased this backup camera for our 40ft RV to replace the black and white one it came with. we are extremely happy wit it.
Answer: I dont know about professionally installation however if is very easy to do if one is inclined to be sort of a do it yourselfer.  Really easy.  Just takes a little thinking.  Cable can run along the frame and come into the interior through one of the rubber plugs in the body.
