The ones I remember in the early 1970's were not like the ones in the youtube clip they were a black sphere with camera lenses poking out at all angles they had the red light and rotated.
They were used in a discount store called Briley's in Peterborough. Frank Briley had a reputation of being a bit of a wide boy, he did lots of publicity stunts involving Walter Cornelius "The birdman of Peterborough". He also had a "fire" from time to time and while the store was being repaired sold his stuff from stalls along the river embankment which was near his shop on the town bridge.
As a kid I remember watching the cameras as they were very Sci-Fi and not seen anywhere else. My dad always said they were fake though as he didn't think Frank Briley would pay for real ones. the shop was a bit run down, you had to watch out for the potholes in the floor...
