Wireless Reversing Camera Interference

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 ebayAV 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

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.
