When using in public places, the height of the operator differs but you cannot change the camera angle. In this case, you can use the auto-tracking feature.
When auto-tracking mode is on, the height of the operator will be detected and the operation area will change according to it. In the aeroTAP 3D camera tab, the operator is marked with a gray rectangle. When you check Enable auto tracking and select Adjust vertical direction, the light blue rectangle (indicating the operation area) will move according to the operator's height.
