The Javelina power supplies take coach voltage and add 5 volts then regulate that number down to 12 volts.
Did your old system have a power supply that you removed?

Everything that powered my original factory installed rear view camera system is still present and (I assume) functioning.  All I did was remove the (useless) original camera, installed the new camera and wireless transmitter, and connected the original power wire to the new gear.  I still use the original dash (MONITOR) switch to turn on the camera.  Only difference is now the image shows up on the overhead 10.5" LCD screen instead of the little in-dash B&W CRT.

So, my best guess is the wireless video while good for resolution, is not up to speed for color.

How is the night image? Ours lacks color at night but has a good image.
Pierce,

You'll see in one of my posts above that I hooked my 2nd identical camera to the monitor in the coach with a video cable.  I then had "wireless" camera on CH-1, and "wired" camera on CH-2.  Switching back and forth showed exactly the same color problem from both cameras.  I don't THINK the wireless modules are the problem.

The night image is in black & white, and is nice and clear, but the range is limited to about 15-20' behind the coach.  Beyond that don't see much.

Is there any way to look at the exterior of a camera and tell if it is CCD or CMOS?  I ordered, and was charged for, a "upgrade" to a CCD camera.  After looking at several side-by-side camera comparisons on YouTube, I am beginning to suspect that what I got was CMOS.  If I did not get what I paid for, then I WILL be P'd Off!.

Will be calling Tadi Bros again tomorrow.  I am determined to get to the bottom of this!

Two possibilities left as I see it. Try a alternate video source into the monitor (DVD player, camcorder, etc) and see if your color image is the same quality or the other possibility would be to bring the camera image into a HDTV and see what it looks like. Most HDTVs have a yellow RCA video input on the side or back.

Somewhere on the camera should be a model number or possibly on the packaging. With that in hand, a google search should come up with the type of image sensor. While CMOS sensors found in some video cameras are very good, most are not as good as CCD. Would think for a camera with night vision like yours, a CCD would be the image sensor of choice. That's why I was asking about the night vision earlier.

CMOS sensors are cheaper to make so it makes sense that an upgrade would include a camera with a CCD sensor.

Have you looked to see if there is some kind of film coating on the lens to protect it during packaging ? Just asking 2 camaras same problem.

Pierce - Good ideas!  I will check my DVR and TV for the yellow RCA connectors - been ages since I even thought about those type inputs/outputs.

Alan - No protective film on the cameras.  The lens on these "weather proof" cameras is mounted behind a glass "window", which I suppose is scratch resistant.

Taking Pierce's suggestion, I continued my analysis of my rear view camera "color" problem.

First, I found a yellow video output on my DVR, so I connected that to the rear view monitor.  Results shown in photos below.  (Sorry about the subject matter - just happened to be on when I snapped the photos)  It is obvious to me that the monitor works fine - it has no problem displaying the full color spectrum when fed a decent signal.

Next, I checked our 37" flat screen, and found a yellow RCA input, so I ran a jumper from the rear view camera to the TV.  As the photos below clearly show, I get the exact same color-challenged image displayed on the TV, so the camera is definitely the source of my complaint.  Wired or wireless, the camera puts out a degraded, basically purplish-brown monotone image.

Following up on my suspicion that I may have been shipped a CMOS camera instead of the CCD camera I ordered AND PAID FOR, I called Tadi customer service yet another time.  I have spoken to the same female employee each time I have called.  Up till now she has been willing to send replacements, but has offered zero technical advice.  This morning, our conversation got truly bizarre.  I asked her if it was possible that I may have received a CMOS camera "by mistake" (allowing them the benefit of the doubt).  She stated that since I got a white camera, it had to be a CCD, because "We only sell one white camera, and it is CCD".  I told her I was sitting at my computer, looking at their website, and it clearly shows that they sell BOTH the CMOS and CCD cameras in white.  She started sounding irate, and said "I don't care what the website shows - I don't design the website - I'm telling you we only sell one white camera and it is CCD".  It was obvious I was getting nowhere with her, so I hung up.  I then called the Tadi "Sales" number and spoke to a salesman.  I asked if I could buy a white camera in CMOS or CCD, and he said "Sure - we have them both in stock, and can ship either one today".  I then asked (if I ordered one) how I could tell which camera I received.  He said "It will be marked on the box".  I asked if there was any kind of identification on the camera body, and he said "No, the only way we can tell them apart is by looking at the box".

This seems like a situation ripe for product "bait and switching".  I have received 2 cameras from Tadi, in identical boxes, and neither box had ANY marking or notation to indicate if it is CMOS or CCD.  I paid $50 extra for the upgraded camera, but they could have sent me either one and there is no way for me to know what I ended up with.  I can't even complain that they cheated me (if they did) because I have no way to prove my claim.  This would be a easy question to resolve, if I could walk into their store and ask to see a demonstration of both camera types.  As a online buyer, I have no recourse, especially when Customer Service is staffed by totally illogical employees.

After I talked to the salesman, I had him transfer me back to Customer Service.  I got a different (male) employee, but I could hear the female yelling at him in the background.  He was sympathetic, but no more helpful.  The way it stands now, I told them I would send one monitor and one camera back to them using a return authorization label (UPS Ground) they provided.  They said as soon as they get that stuff back, they will send me ANOTHER camera.  I asked if it would be a white CCD camera - He said "O yes Sir, we guarantee the box will be marked CCD".  I'm pretty confident THAT statement IS true.

I retract any real or implied recommendation I may have EVER given to Tadi Brothers - find another vendor if you value your sanity (and your cash).

There a lot of factors that play into the image quality of a video camera. The type of image sensor is just one factor, and not necessarily any more important than many others. For instance, I have a 6 or 7 year old HD video camcorder, a Sony HDR-HC1 2.8MP High Definition MiniDV Camcorder w/10x Optical Zoom, 1/3-inch CMOS sensor with 3.0-megapixel still-image resolution that takes terrific 1080i video. There are advantages and disadvantages to each type of image sensor. It is as much about the quality of lens, the aperture (not only the lens but also the grid of the image sensor). Heck, even my iPhone 5s takes pretty 1080p video...
It bugs me when these vendors selling back up cameras and cheap security cameras with a composite video output claim to be HD, when they don't even have a connection that will support an HD signal (i.e., HDMI, DVI, SDI, Display Port, etc. for digital, and RGB which uses at least 4 conductors, Component which uses 3). I suppose, it might be "high definition", if you allow the term to mean a  somewhat better image when compared to another camera...
When I was looking for a way to get an HD image to a dash monitor, I kept coming across the term used so loosely that it was meaningless. I finally settled on a security camera which is IP66 Weatherproof, has a 3 to 1 Optical zoom, and an SDI (Serial Digital Interface) output. It was a fair amount of work, but I remain happy with the results. It was also part of the whole in-dash computer install, and as such required a bit of extra pieces to make it work. Finding a 7" monitor bright enough with a decent native resolution (1024X600) that would work for both the monitor and the computer, an SDI to HDMI converter (all digital, no loss in quality), a 4X2 HDMI matrix switcher to name a few... It boggles my mind that there doesn't seem to be any providers who make a turn key system like this. Even the systems sported in newer IH45's, Newels and Prevos are SD camera systems. They do have pan and tilt cameras, and multiplexed auto switching displays, but still with SD over composite video cables... People who have these great coaches deserve better options! Rant over...
Of course the most important thing is that the visibility is there when you need it when backing up or changing lanes, and these systems fit the bill for that... I just wish they wouldn't use the term HD, which actually has an accepted international definition (at least 1280X720p or 1080i).

Don,

Perhaps the builders believe that by the time customers can afford high-dollar coaches, their eyesight is so poor they can't tell the difference!

Didn't they have a old video standard called LDTV (Low Definition)?  These backup cameras should be labeled LD.  If you can see a image, and actually guess what it is, then it meets the requirements.

Well, duh of course HD uses HDMI cabling I knew that but never put HD back up system together with HD cameras,  displays and the required cabling. One hundred per cent correct again Don,  you don't run an HD for image through the cabling they put in our coaches 20 years ago. However the system is great for backing up, keeping an eye on the toad  and the wide angle lens picks up vehicles coming around you, just not very good for watching a TV show. :P  Wouldn't be without it and until Chuck mentioned it never noticed how terrible the colors were.

The first thing I thought of when I saw the pics was that the monitor was producing the red yellow and green backing guide overlay so it had to be the camera. Not the sharpest knife in the drawer but sounded logical to me. But of course I don't know how the overlay is configured.

The red/yellow/green "range marks" or backing guide or whatever its called, is generated within the camera.  You can see that in the last set of photos I posted...they show up even when the camera is connected to our 37" flat screen.  Included in the wiring harness coming out of the camera is a small 2-conductor wire with the ends of the wire stripped bare.  According to the instructions, if you wrap the bare wire ends together BEFORE you apply power to the camera, the "range marks" will be removed (turned off).

Howdy Chuck,
  I'm wondering if you have resolved the color issues?  Would you still buy and install this system?  Replacing my backup camera and monitor is next on my never ending list of "things to do".

Dave,

In my last post on my dealings with Tadi Bros I was waiting for them to send me a THIRD camera.  Well, they did, and true to their word the box was marked to indicate it was a "CCD" camera.  Unfortunately, the (identical) camera was neither better or worse than the previous two - the color is still terrible.  I sent the 2nd camera back to Tadi, kept the 3rd, and told them they wouldn't hear from me again.  Sweet news to their ears, I'm sure.

I will keep the Tadi system, because it DOES do the job.  The image is clear, and it is easy to discern objects behind the coach.  I have taken 2 trips since installing the system, and I find it VERY useful, especially for passing and merging back into lanes of traffic.  It works beautifully for backing up the coach, and gives me much greater confidence in all driving situations.  I would say it is essential when pulling a towd.

I did have the opportunity recently to look at Bill Chaplin's rear view camera setup, and the (poor) color rendition on his unit is very similar to mine.  I believe his is a wired rear camera from a different manufacturer, and was installed some time ago.  I have seen only these two examples of aftermarket rear view systems, so I don't have much to go on, but I may be asking too much of these cameras.  Perhaps accurate color is not a high priority?

To answer your question, YES, I would install this system again.  The wireless installation is very simple, and works flawlessly.  My only real complaint is the color rendition.  I may eventually try buying another camera, and see if I can get better color.  Because the camera and transmitter are separate devices, you can use any camera with this system.

If I were you, I would shop around and consider the features versus cost of "wireless" systems from other sources, before deciding on the Tadi offering.  But that's just me...

Here is a shot of our monitor. Used OEM wires. Taken just after I installed it about four years ago. Not high resolution but the colors are good. About $60 for the rear camera/ monitor package delivered with another $60 or so for a wireless transmitter. Wireless transmitters at: wireless video transmitter | eBay Make sure wireless model is 12V.

So, what do you think of the "colors" displayed on the monitor?  Does green grass and green leaves on trees look green?  Are other colors rendered accurately?

Craig,

Thanks!

I looked at the sliding coffee/map/etc table and after finding the stop for it, I removed it and installed a bracket screwing upward to hold it in place. Then I used another screw to put the mount for the monitor in place on top of the new bracket. Slid table back into place and away we go.

Like to have a second camera/monitor for the famous GV blind spot. I come close to crushing a car at least once on every trip unless Gaylie is in the seat over there. Got to hear 10 seconds of Bosch horns from a late BMW the last time.

Dave A: our camera/monitor is still working well about 4 years later. Don't know about the quality of the wireless they include. Suspect that it could be short on range at that price as is probably designed for a car. I see some of the others advertise 150 meters. I just wired ours using the stock wires and coax. Image at night is outstanding. You can see how many IR projectors it has in the photo.

So you still have the OEM camera/monitor in operation? If so, where did you mount the LED cam?

No, the OEM was DOA when we bought the coach. LED cam is mounted in the old location. See my photos at: https://plus.google.com/u/0/photos/100921130470085833749/albums/5593685542808777185?authkey=CJW2kP3fn7f2XQ

They show the new monitor location on the dash, a close up, the LED voltmeters I installed in the Audit CRT location as well as how I mounted the new camera and used a router to mount the camera before putting the finishing plate on. It is waterproof so it just sticks out.

Sorry for my poor explanation as my ADHD never allows me to put more than a couple of sentences together without going off........look, a chicken.
