Have you tried taking the connections loose and cleaning them on the back of the monitor also? You can go wireless but I would determine which part of your system is failing, either monitor or camera, and then just replace that bad part. You can upgrade either end of your back-up system, using your existing wiring, with the use of some adapters. Of course that all assumes that you do not have a problem with the wiring itself.
