Obviously, I can't tell what yours is/is not doing. But we started getting strange activity on our back up monitor just as we set down for the winter. On the docket was new coach/house batteries. We put our heads together and figured the camera is powered by the house batteries. When we changed the batteries, all was well. We've traveled about 3000 miles since and nary a problem.
