Dual reverse camera setup. Want 1 to be wireless.Please help

Take a look here. Many options. I was able to make up my own package at a great price. I would avoid the monitor that hangs on the rear view mirror. There was a great deal of glare. It washed out the image. I exchanged it for a dash monitor with no problems. I am happy.
