ABSTRACT:
A full viewing range system for video monitoring of a surveillance area. A first reversible drive preferably is suspended from an overhead support structure and has a first drive shaft that is free to rotate through a substantially full three hundred and sixty degree arc. A second drive is connected to the first drive shaft by an offset connecting member. The second drive is disposed perpendicular to the first drive and is offset a selected distance from the axis of rotation of the first drive shaft by the offset connecting member to center the second drive to one side of the axis of rotation. The second drive is free to rotate in substantially a three hundred sixty degree arc about said axis of rotation. A camera mounted on the second drive shaft is free to rotate in substantially a three hundred sixty degree arc thereon. The viewing axes of the camera are controlled preferably from a remote location by selectively rotating the drive shafts, providing a global view of the surveillance area.
