Every type of CCTV camera, taken apart, with the physics that decides what each one can see: bullet, dome, turret, box, PTZ, fisheye, multisensor, multi-directional, thermal, bispectral, plate reader, covert and battery cameras. Why domes fog at night, what C and CS mounts are, why 30x digital zoom shows a face as two pixels while 30x optical zoom shows seventy-five, why a 12 megapixel fisheye only uses about seven, how stitched panoramas double people near the seams, and why a thermal camera can find a person 200 metres away in total darkness but cannot tell you who it is. Every number is sourced below.
