The fisheye security camera mounted flat in the middle of the ceiling and pointing straight down: a circular image in a black frame, with a white line of text below for the camera name and time. The room becomes a floor plan: beds, sofas and tables are seen only from the top, the walls, doors and windows fall outward around the rim, and people are just the tops of heads, shoulders and backs, foreshortened toward the floor. At night it switches to infrared black and white.How to prompt: start with <code>ceilingfisheyecam, overhead circular fisheye view of</code>, then the room, then say plainly that the camera is in the middle of the ceiling pointing straight at the floor: furniture seen from the top, walls falling outward at the rim, people seen as heads and backs. Then who is where doing what, and finally the camera label and timestamp (e.g. CAM 04 DORM 312 2026-11-02 21:14:33) and color or infrared black and white. Without the "straight down" part it tends to come out as a corner camera at an angle with a circle pasted on.
