In order to set up the correct coefficient for your camera, use the Calibrate button in the Camera tab, or consult the full set of manual set up instructions below. |

+ | **Camera Shift** describes the distance the machine will move by if it does not locate a marker after it has been instructed to look for one. This can happen when the marker is not fully within the region of interest, and then the camera will keep on moving around until it either finds the marker or reaches the end of this specified Camera Shift. It is set automatically in the newer software versions during the calibration process. | ||
