VIP room of former Epcot Horizons pavilion had a video "window" with robotic control of a rooftop camera, and a camera facing the pavilion. Current state of of the pavilion-facing apparatus.

Robotic camera system that was on the roof of the old Epcot Horizons pavilion. Covered for service. Guests in the General Electric VIP room could remotely control the camera. Video was seen on a large screen, substituting as a window into the park.

A glimpse of the audio/visual control panel in the GE Executive Club (Epcot Horizons VIP room). Best I can find right now, a paper printout of a screenshot.

It was a color user interface, mouse operated, on a Sun Microsystems workstation. All icons custom-drawn.

1989 video clips showing the cameras (one on robot) and views that guests had on a large video screen inside the GE VIP room in the Horizons pavilion at EPCOT. See also earlier tweets in this thread.
