First generation video surveillance techniques involved constant monitoring because there was no way to record or store information. Reel-to-reel media was developed that enabled the recording of surveillance footage. However, since these systems required magnetic tapes to be changed manually, it turned out to be 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. Later, VCR technology became available, making it easier to record and erase information.
After several decades of VCR usage, digital multiplexing was developed, allowing several cameras to record at once, as well as time lapse and motion-only recording. This increased savings of time and money and the led to widespread acceptance use of CCTV.
Currently, CCTV technology has been enhanced with internet-based products and storage systems, and enhanced technological developments.
