Steve, the others are correct. This is not a mounted camera, nor is it pan, tilt, or zoom.
Your PELCO stuff (I've worked with PELCO cameras; they're not bad) shows only that PTZ cameras exist, not that this is one. It's easy to tell that it's not.
First, no halfway decent security person would put a pan or tilt camera in a corner where this is. See that corner of wall on the left in the foreground? It negates the pan and tilt features. No, if a camera were put in this corner at all, its sole purpose is to observe the door, in which case it would be totally immobile.
Second, watch the top right corner of the transom. See how it cuts off in one of the frames? That action is not attributable to either pan or tilt. The camera mount itself had to move for that to happen, and since no actual mount would move, that means the camera is on something moveable, i.e, someone's hand.
Third, there is no zooming at all in the picture.
Fourth, the PELCO information you quoted does not describe a pre-programmed pan, tilt sequence; it describes a camera with an 8 position joystick for manipulation by someone monitoring the displays at a console somewhere. If that were happening, then this was observed, but the story makes it clear it was not observed.
This is a hoax, Steve. Self-evidently so.
