During the 1990s, digital multiplexing was developed, allowing several cameras to record at once, as well as time lapse and motion-only recording.

There are about 350 million surveillance cameras worldwide as of 2016. The growth of CCTV has been slowing in recent years. Very little is known about Vericon except it was advertised as not requiring a government permit.

The earliest video surveillance systems involved constant monitoring because there was no way to record and store information.

The first use by local government was in King's Lynn, Norfolk, in 1987.

These were deemed successful in the government report "CCTV: Looking Out For You", issued by the Home Office in 1994, and paved the way for an increase in the number of CCTV systems installed.

is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors.

It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint (P2MP), or mesh wired or wireless links.

The development of reel-to-reel media enabled the recording of surveillance footage.

These systems required magnetic tapes to be changed manually, which was a time consuming, expensive and unreliable process, with the operator having to manually thread the tape from the tape reel through the recorder onto an empty take-up reel.

Due to these shortcomings, video surveillance was not widespread.

VCR technology became available in the 1970s, making it easier to record and erase information, and use of video surveillance became more common.
