I wouldn't be surprised if the ones used in Boots were the same inside as the type that bigclive takes apart.
Anyway, they do remind me of this:-

Going back to my earlier comment about being crude inside. Well yes clearly the rotating mechanism is well made, I mean look at the lovely laced cable-form in bigclive's video. However, as I child I always imagined that an operator could turn it at will to track an individual. It never occurred to me that it simply rotated a small amount at regular intervals.
Of course a camera that rotates every so often is not that useful in practice. Fixed cameras directed at points of interest such as the doors, the tills and aisles by high ticket items are of much more use, but perhaps less of a deterrent.
