The white Large Universal Ceiling Mount from PTZOptics is a two-piece assembly that supports any PTZ camera, even larger sizes, with a 1/4"-20 mounting interface on the bottom. It attaches directly to the ceiling and the camera attaches to it upside down. The bottom piece is flat and therefore any size camera is supported. This mount can also be used to attach directly to U.S. single gang device boxes, junction boxes, or European single gang boxes. All necessary mounting hardware is included.
