What camera has a wire long enough for our GMC's? As some I've looked at don't say how long the wire is to the rear. I know there are some that are wireless. But I'm not interested in having another device that needs batteries. The main reason I want it. Is that when I'm all done. I'll have no back window that I can look out of.Bob Dunahugh 78 Royale.

The wireless ones don't need a battery. I have a set wired to my brake lights. It is a 12 volt system consisting of a camera and transmitter in the back that are powered from the brake tail light, and a monitor and receiver in the front that are powered up with the ignition. That being said, if I was doing a full restoration I'd do wired as the wireless quality is easily interfered with.

Jeremy,
Your rear view camera only works when the brake lights are on??? Seems to
me that's not very useful "going down the road".
My solution to the same problem was to tie into the tail lights. That
reminds me that it's a good practice to have headlights on even in the
daytime -- no rear view means I need to turn the lights on. Not as neat as
an on-with-ignition setup, but lots easier to wire.

You are right. That would be pretty useless. Apparently I need more coffee. What I should have wrote is my rear view camera is tied in to my backup lights. So it only comes on when I go in reverse. Tail lights would be a better idea, I just never really found the need to have it on when going forward. Maybe one day I'll switch it. Good catch!

Bob,
On my "wireless" back-up camera, (Yada from Costco, not great quality, but okay) only the video signal is wireless. It still needed a power wire. The wire that came on the camera was about 10' long. I ran it up under my ceiling to about the location of the center roof AC, grounded the black wire to the aluminum roof framing, and extended the red hot wire to the dash.
I took ignition switched power from the fuse block behind the glove compartment, and ran power to a switch on the dash. I then powered the camera and the monitor from that switch. I could have done as Ken did and just turned on the running lights when I wanted to use the camera, but I decided to do it the hard way instead.

When we first got our coach, it had a wireless backup camera powered from the backup lights. There was also a power switch you could use when going forwards but the downside is the backup lights would come on. This was very annoying to following traffic. The wireless signal left a lot to be desired with lots of dropouts and generally iffy images.
So when the backup camera system died, I replaced it with a wired model. Now I get a crystal clear color image that auto-adjusts to night vision and I have it powered by a switch in the dash when ever I want/need it. We usually have it on all the time as I like to be able to confirm what is or is not behind me. I mounted the camera monitor to the internal mirror mount so in essence the camera becomes my rear-view 'mirror'. The system I purchased has a head control unit that I can attach other cameras to as well and it came with more than enough cable to get from the back to the front. Kind of pain to route the cable and hide it as much as possible without resorting to stripping out the cabinetry but I go t it to work.

That's a real bargain Ken. The Yada I got from Costco (as a gift) was about $30.00 more and only has a 5" monitor. It seems satisfactory though after working out a few initial problems I had with it.

Bob,
Fish camera's make good rear view cameras, and can be hardwired(charges via usb).
http://www.aquavu.com/Products/Aqua-Vu-Viewing-Systems/AV-Micro-II
I am sure there are cheaper ways to do it, but thought I would toss out that option. I won one at a fish contest, and will eventually get around to using in the coach as my rear view camera. Color, IR capability.

The video 'wire' is actually 75 ohm video cable. Available at WalMart or via the web.

My coach should hopefully be on the road within the next 60 days, and my plan was to try and kill two birds with one stone by installing a Garmin RV 760LMT GPS with the BC20 wireless backup camera. I was going to power the camera through the tail lights. In Canada we have mandatory daytime running lights, which means that there would always be power going to the camera.
Two questions if I may:
First, a couple of comments in this interesting thread suggest that wireless translates into poor and possibly even intermittent picture on the GPS screen. Is this a function of the quality of the unit, or is it a generalized problem. I am hoping that with Garmin being a premium brand and my coach being a 23 footer, that I will be OK without fishing wires.
Second, since the lights will always be on, the camera will always be powered. Can I presume that there is a toggle on the GPS screen that allows it to switch back and forth between the GPS function and the backup camera? I scanned the Garmin literature and didn't find a specific confirmation of this.
Thanks in advance for any answers.

Gordon,
The quality of my picture is good, not excellent because the colors are a
little washed out. The biggest problem with the wireless cameras is that
they all seem to operate on the same frequency so that in the right
position, you may see someone else's view. The only time it's happened to
me was parked at Bean Station only 15'-20' from someone who had their
camera on while my receiver was powered but the camera was not. A VERY
minor problem, IMHO.
I do occasional have have a video drop-out, but not often nor persistent.
For my cost, it's tolerable; better units are probably less susceptible.

My thoughts.
Wireless = too lazy to do it right. Also, too many things are now "wireless" meaning that there will be collisions in the data being transmitted. Depending on where you are and what other channels of strength around you, your image quality could be problematic in some way either for you or another device.
Two cameras are better than one. Since you will have no rear window, i'd recommend a two camera system since motorized and pivoting cameras seem to have disappeared from the landscape. They did exist ten years ago. The two camera system will give you a view down the road and a view (when switching on the monitor from A to B) of the bumper, hitch, and towed vehicle also makes sense. On the SOBs, most cameras point to the hitch/towed. When I had another coach with the pivoting camera, I started using the "down the road" view as much as my mirrors.
Monitor size - it does make a difference. Avoid anything that is the size of a rearview mirror. They become impractical. 7-inch is the minimum.
Several monitors allow you to hook into an installed GPS. Problem is, most monitors will accept only two inputs. Some are coming to market that will support four (left, right, rear, GPS). GPS radios that hook to those monitors are, in comparison to all-in-one units, very expensive. Their price still needs to come down. Apparently they are going after the after market of people with cars built before 2012 and which includes getting a radio, bluetooth connectivity, etc. They aren't going after the RV market.
Wiring to the camera - it depends on the brand of camera. Some will use anything suitable for RCA video/sound.
Sound -- having a microphone back there will come in handy. When I back up I turn up the volume to hear the discussions of the folks trying to help me back into a site. Gets humorous especially when your wife calls you an SOB and isn't referring to Some Other Brand. Audio does help overcome the lack of understanding as to what all those signals mean. This, of course, assumes the one doing the signaling has had no training.
tadi.com seems to be a good source and gets high marks from customers. There are real people on the phone there and they do speak 'Merican English.
Camera on license plate - these are made for automobiles where the plate is in the center of the vehicle and there is no high point on which to mount a camera. Therefore the field of view of the camera is restricted. I don't view this as optimal for a motorhome or any higher and longer than a van vehicle.

______________________________________________
I started out with a wireless camera. I mounted it inside at the top of the rear window, connected it to a toggle switch (ran a cable all the way back to the camera) on the dash. I wanted to be able to see who is riding my bumper while driving and of course to assist while backing up. It worked fairly well. Only downsize being that it didn't work well at night and there was no sound. But it was cheap. New ones apparently can work at night.
A few years ago I decided that I wanted something with a bigger display and could support multiple cameras. Reason being is that I frequently backup on to roads with traffic and wanted to be able to see what might be coming. Since I travel frequently alone, I could not rely on someone to look out the back window to alert me to traffic.
After a few sessions of Google research, I decided on the "Rear View Safety RVS-770613 Video Camera with 7.0-Inch LCD". Available on Amazon. It has inputs for 3 cameras, has sound and a decent size display. I pulled the rear headliner out and installed the 3 cameras and cables (you can order them in a number of lengths). Got it all wired up and so far it works great. Now I can see traffic on both sides as well as rear. It works at night and can pickup audio. It also has the ability to tie in to the turn signal switch to automatically switch views to go with the turn signals. Another useful feature are the "distance grid lines" that can be turned on to show the distance to walls trees or other obstacles while backing up. I use that a lot.
