My "original" wireless back up camera worked pretty well most of the time.  Sometimes I could not get a signal and when I would go through an underpass or by a big wall it would seem to reflect the signal and I could see the toad. It was at best unreliable at 40 ft.

I just got a new one and have not yet installed it. On this one there is an antenna that I can extend to the front or part way toward the front of the bus --- hopefully it will work better.

I agree the range that is in the package is usually very optimistic at best.

Dave,

The camera has pretty much a straight line-of-sight from the camera to the monitor. The monitor is on the sun visor and the camera is on the rear shelf about 1/3 the way up the rear window. 

Bill's post gives me an idea. If you have no wire on a switch to the rear you could hook the camera power to the running lights so all you need do is turn them on when you need the camera. Of course the camera would be on all the time at night but that not usually a lot. Even then you can turn off the monitor when you don't want to have it on.

Well Lo and behold, I moved a cabinet in the garage this morning and when I emptied it I found a brand new 5" color monitor and a 6mm wire-in camera. I found the instruction books and set-up guide and guess what??? After reading it , the entire instructions make absolutely no sense to me what so ever. (A lot has to do with the fact that the product comes from China and the book has obviously been poorly translated so the words don't make all the sense that they should.) (Plus I bought this 5 years ago and I am not sure that I have all the parts I need.)

How can I transmit what I have (info) and seek guidance from all you pros out there as to how to hook up?

Don't get me wrong I am thrilled that I found this stuff, just concerned about installing it correctly.

Can anyone help me on this one?

pretty sure that as usual a picture is worth at least a thousand words.  If you post pics of the components, the wiring ports on each with enough detail that we can read the labels, the wires you have etc...someone here will put you right.  We are talking setting up your car stereo level of complexity so it will be doable.  Posting pics of the instructions will help as well

Dave,

Google  the model and name and you can probably find a newer, better written instruction manual. I've done this with numerous things.

The confusing Oriental to English translations can usually be clarified after closer reading. I find many of them very funny but can usually figure out what they mean. Sometimes they call electrical "ground" "earth", very British.

A picture of the actual parts you have would probably help confirm that the instructions match that gear.

The instructions talk about a wireless receiver for a wireless camera, while the diagram shows a wired camera. However, assuming they are the right instructions for whatever parts you have, they do make some sense.

The "6-pin to RCA connector" is the pigtail adapter connected to the monitor in the diagram. This has 3 RCA connections, two of which are video (Yellow and Red), and one which is audio (White). You're supposed to use Red for the backup camera. Yellow is your aux video input, which means you probably won't use it. So plug the video (yellow RCA plug) from the wireless receiver into the red connector on the pigtail. Then you need power to the power connector (red being +12V, black GND). And there's a single black wire labeled (backward in) that should go to your backup light power (so the monitor will use the backup video input when you go into reverse). If you don't have that, or it's not easily available, you could add a panel switch to flip instead...connect it to 12V.

The camera and wireless receiver also need to be connected to power, of course. Given how far apart things are, I'm sure you wont be sharing power connections like the diagram suggests.

As for the wire labeled "backwards in" I'd just go ahead an put it on a switch so you can run it while going down the road to check on the toad & etc!

Usually "backwards" or "reverse" means the view in the monitor is the same as in the rear view mirrors.

and then on e bay get a 7 incher http://cgi.ebay.com/Access-HD-7-inch-Portable-Digital-TV-Brand-New-Box-/120732013239?pt=Televisions&hash=item1c1c3052b7
run the power off the tail lights and all you really need is one wire for the center of the video as you can ground the shield but i would use 2 wires [coax]

Any wireless working in the 2.4GHz will be susceptible to interference from a host of devices. 2.4Ghz is the natural resonance of water, so microwave ovens and humidity will affect performance. The guy driving by with a wireless ipod transmitter in his cigar lighter will attack the signal, your laptop may well interfere as well. There are only 3 non-overlapping channels in that frequency range, every device MUST accept interference and is limited in power output.

 I know nothing about backup cameras (other than I have an ancient BW in the S&S) but every 2.4GHz device I have worked with in the last few years has experienced interference issues. Are there any camera systems up in the 5GHz range? Many more channels available and less devices playing in that range.

We had a 2.4GHz scanner in our truck and when the kids were younger they would shout McDonalds every time it went off, their ovens gave off such a strong signal!
