I asked about that issue when I was at the factory. They explained that it can't be done because of the type of camera. It's an "el cheapo" camera designed only for intermittent use... using constantly for long periods of time will burn it out.
Having said that, it CAN be rewired by taking the power from a source other than the power to the back-up lights. However, you then have to turn it on and off manually using the button on the mirror, each time you use it. Remembering not to leave it on too long at any one time... :-(
The solution was to add a wireless camera designed for extended use.
