True, though CCTV or Closed Circuit Television used to be “fully loca” l and “closed”. Tapes and recordings were only available or accessible to the property or person in most situations being recorded over older recordings.

Newer tech now is interconnected with companies trying to infer extra information from full databases of recordings from multiple different locations all around a town or city, or state.

CCTV used to be like a security guard sitting on a lawn chair. Where modern security cameras/systems are like having a personal tail following you all day and night.
