Since the camera is fixed, it's FOV is going to be fixed, so really, in actuality, what is the point of actively moving the zoom/focus portion of the camera for any reason but maintenance purposes. If you want a PTZ, you buy a PTZ. If you want a large coverage without a PTZ, you buy a fixed lens or a fisheye/panamorph MP camera and dewarp via software or multiple streams.
The purpose of a motorized lens is to simplify maintenance and initial setup, not be used to fix design criteria. The motors are not robust enough to support this; look at the construction of a PTZ vs. a camera with motorized zoom and focus. Huge difference.
