I am looking at installing a wireless reversing camera to my van. I already have a screen in the tow vehicle. I have heard of some interference problems with 2.4GHz models (but not apparently with 4.2GHz models?). The 2.4GHz models are quite a bit cheaper.
Can somebody tell me if the interference is restricted to petrol vehicles, or if it has also been experienced in turbo-diesels?

I have 3 different types of AV wireless transmitters 2.4Ghz and finally used 2.
I have decided against an integrated wireless camera because I can position the transmitter independently and closer to receiver to minimise interference.
I have 2 sets of 2W 2.4Ghz transmitter/receiver in a metal housing with 9V supply voltage. While the transmission quality is good the housings get pretty hot and I do not want that to operate long time because of fire danger.. really hot.
I use these 2 only for my 2 cameras on my truck camper while I load up, so the heat is not a problem.
I also have tried a set of 12V supply indoor units and while there is no heat problem with the housing the image quality is poor.
I have use one set with very satisfactory results. Here is a link on ebay
AV transmitter
He is charging too much and too much postage but thats the product I am happy with. It has 12V supply for the transmitter and a 5V supply for the receiver with - in center of pin. Very odd pin out and voltage but thats not a problem when you know. The image quality is very good and no heat problem.
I would bring the transmitter to the front of the van and the receiver to the rear of the vehicle so you have minimal distance and maximum quality.
Works
well ...
good luck

Thanks for your info gmd. That really looks like a bit of overkill to me. I am looking at a system like this one:

well .. you try it .. cheap enough to throw it in the bin.
I have a total of 11 cameras in use on my truck camper and vehicle
connected through quad processors and auto serial switches connected to 4 different kinds of screens. I have used number plate cameras, small and larger night vision, bullet cameras, butterfly cameras and my conclusion was to separate camera and wireless transmitter to achieve best results. The number plate camera was the worst quality and I use it exclusively for the tow ball when I couple the boat trailer.
You decide .. just giving you info ...
good luck .. you will probably need it .. lol

I have tried every combination of cameras and screens and found the wireless ones to be useless.
Why Because of the amount of metal between camera and receiver.
Even putting the receiver at the back of the car made no difference.
The one you see on Ebay may be different because of the wire to allow a change of position for the sender, but I doubt it.
However if you are going to run it to the front of the van and the receiver to the back of the car you might as
well buy a wired one and know it will work
The wireless one I had wouldn't work properly on the back of the van but if I stood out to the side in line of sight of the receiver it worked fine.
Easiest way is to use a wired one and run the power off a side light on the van and run the video wire under the plastic cover over the screws on the edge sealing strip, then up through the chassis to the towball.
In answer to one posts heat problem I found that 12 v was too much for the camera and bought a little stepdown power board at Dickies and ran the camera on 8 volts and it worked and didn't get hot at all.
Try it with a 9 volt battery and see what difference it makes, thats what I did first.

I run them on 9V
does not make a difference.
I dont have your transmission problems though.
You are right with a wired solution. Cheaper .. probably easier
but not very "elegant" .. lol ..
I had been thinking about it but I wanted two cameras on my camper while I reverse under it when I load .. thats very awkward with cables .. \
so I experimented until I found a solution that works ..
The product I mentioned works very
well over more than 30' through walls
have fun

I second that Graham, just got
mine out of the box and it is 2.4 GHz.
Next to useless for me, that's why it is still in the box.

Like Graham, we had too much metal on our van for the wireless, although the same model worked fine on someone's Jayco. It would work when inside the van, but the final layer to the exterior was just too much. We were able to add wires to it and hard wire.
