Normally the camera order is set when the installation of C3 is done in a vehicle, but it may also be done afterwards by using the Camera order function in OEC.
To set a new camera order, select a vehicle with C3 enabled cameras, go to the Cameras tab, and click the Camera order button.
Several arrows will now be visible, simply click on an arrow to move a camera up or down until the cameras have the preferred order, then click on Save below the camera list.
