The Evolution Of CCTV

Each piece of technology has humble origins- even our most modern inventions today will seem comically behind the times in the future! This is a great sign that technology is always evolving to meet the demands of humanity.

CCTV is widely used throughout businesses and homes alike. And while now we know it as a top-of-the-line way to offer complete protection and security, it took quite some time to get to where it is today.

The First CCTV

The first version of CCTV was created in 1942. Seven years later, CCTV became widely available and began being used by security companies and various government agencies.

VCR Tapes and Multiplexing

In the 1970s, CCTV surveillance was able to utilize VCR to store recordings of footage. While this marked a pivotal moment, it also highlighted the drawbacks of VCR.

Twenty years later, the pivotal change with CCTV occurred: multiplexing! Think of the typical portrayal of CCTV in movies or shows- you probably can recall seeing a TV with multiple camera angles. That’s multiplexing! It allowed multiple streams to feed into one TV- saving time and storage.

DVR, NVR, and The Future

The last 23 years have brought major changes to CCTV- and the future continues to be bright!

DVR (digital video recorders) debuted in the early 2000s and allowed for even larger storage and clearer imaging. Today, CCTV utilizes NVR (network video recording)- which allows for remote streaming, nearly unlimited storage, and can be streamed to multiple devices.

As for the future…we can never know until we get there! The last few years have shown the collaboration of drones with CCTV and AI being used to scan CCTV footage.
