What a difference a few decades can make in technology. In the field of video surveillance, it is considerable. In its beginnings in the mid 1960s, a closed circuit camera was linked to a monitor for a live feed and observed by an individual at all times. If an illegal activity was observed, security personnel were notified and sent to the offender for apprehension. Video surveillance genuinely hit its stride when video cassette recorders hit the market, making it possible to record and retrieve evidence that would uphold in court. There was an explosion of video surveillance activity around the world as this technology hit the mass market. It was especially prevalent in law enforcement, traffic control and divorce proceedings.
