    Who remembers the 80s style Dalek CCTV cameras? Usually found in big retail stores.

    Any idea how they worked? I seem to recall that CCTV camera modules were very bulky at that time.

    There were five full camera in each of those modules. The later ones had the camera offset in the hemisphere so the camera bodies could overlap each other. The hemispheres were much smaller with the same cameras inside.

    No special technology, just a camera and a cable back to a video board. The video board switched signals manually or automatically (depending if security wanted to monitor one specific individual or rotate scans of the whole store.

    Yes, because they used a tube for the sensor -- not a semiconductor imager like a CCD.

    edit: Arrrg. I can't embed an image of an old camera for some reason.
