I am sure that there is a manual adjustment that you can make (up, down, left, right) by getting on a ladder at the back of your RV. If you want to be able to pan or tilt or zoom the camera by remote control (such as while driving), there are some upgrades you can add that do that. Google "PTZ Cameras." \ken
PS. Changing to a PTZ camera is going to require other cool(!) upgrades, as well.
