Contact RVCAMS.COM. They can give you any help that you need to buy the adapters so that your existing cable can be used with any new cameras. A wireless camera sounds great but it is not completely wireless. You still need to have power to it and you need to have a way to turn the power on and off. My experience with them is that the picture image is NOT as good as the wired cameras. I have one wireless camera that I use to tell when my fuel fill is next to the pump. RVCAM.COM is very knowledgeable about Voyager products and can take care of all of your needs.
