CCTV cameras have become part and parcel of everyday life. We see them on the tube, in shops, offices, trains – and surveillance is now so commonplace we often don’t give it a second thought!
However, the history of CCTV is extraordinary, and the technical capacity of cameras has innovated substantially since this form of surveillance was first introduced.
Let’s take a trip back through time to look at when CCTV was invented and how it has evolved into the formats we see today.
When Was CCTV First Used in the UK and who invented CCTV?
CCTV was invented by Walter Bruch and was first used back in 1942 in Germany to capture live video footage. Operators used these early forms of CCTV in wartime to monitor V-2 rockets.
It wasn’t until seven years later, in 1949, that CCTV became available commercially. It quickly gained interest as an advanced security control and was picked up by the governmental contractor, Vericon, in the states.
CCTV reached British shores in 1960.
Back then, CCTV wasn’t anywhere near as technical as it is now. Rather than automated sensors, infrared cameras and body temperature detection, they provided live monitoring, streamed to monitors – without the capacity to record the footage.
These days, there isn’t much CCTV can’t do!
- Real-time feeds are available through mobile devices and remote monitors.
- Wireless installations are available with solar-powered batteries I.e CCTV Towers.
- Automatic sensors activate CCTV when movement or breaches are detected.
- Alarm monitoring services provide instant responses when an alert is raised.
Still, it’s taken 80 years for CCTV to develop into the systems we rely on today, and it’s well worth reminding ourselves of the fundamental technology that allowed this innovation to happen!
How Has CCTV Evolved Over the Last Eight Decades?
To get a good idea of how CCTV surveillance systems first started, we’ll go right back to the beginning.
After the initial systems, designed by Bruch, engineers introduced reel-to-reel recording systems. These could capture footage but still required ongoing manual controls, with an operator needed to thread tapes through the recorder and be ready to switch them over.
This system proved too fiddly to use and was quickly outdated when VCR recording arrived in the 1970s. VCRs became widely available, relatively cheap to run and buy, and were a far more convenient solution.
The benefits included leaving the VCR to record and run autonomously and then going back to look at the footage later on.
However, there were still some issues:
- VCR tapes had a finite capacity and still needed to be changed regularly.
- Tape libraries required a large amount of storage space.
- Most CCTV users would need to tape over old tapes to avoid having a limitless library of footage, and over time the videos would wear down.
Next up came multiplexing, around 20 years later in the 1990s.
Multiplexing solutions mean that multiple signals from multiple CCTV cameras can feed together onto one monitor.
This concept was ideal for larger organisations or businesses who needed to protect several areas at once – and we’re all familiar with the site of a security office at a large property with multiple feeds showing all of the entrance points, communal areas or stairwells.
We were still reliant on VCR recording, but this development dramatically reduced the physical storage requirements. For example, if four CCTV cameras were streaming to one monitor, you would require a quarter of the storage capacity.
When Was Digital CCTV Introduced?
In the present day, so much of what we do is facilitated by digital technology. In the 1990s, concepts such as smartphones, Wi-Fi, and indeed broadband were figments of imagination!
When digital technology became mainstream in the early 2000s, CCTV changed forever.
- VCRs are now replaced with DVRs (digital video recorders) with significantly greater storage capacity, speed, and image quality.
- Multiplexers remain in use and are built into CCTV systems meaning they take much less time to install and manage.
- Digital footage is stored without the need for any manual tapes, making CCTV security far more accessible.
Pricing is also a significant factor. New technology is expensive. While CCTV has been around for several decades, when digital systems first became available, they would only have been affordable to high-value organisations with the budget to invest in this security.
Now, digital technology is widely accessible and affordable, whether for small businesses, private homes, or larger commercial premises.
In 2021, we haven’t stopped innovating, and there are new frontiers still out there, which will make security faster, easier, more convenient, and potentially cheaper!
NVRs, (network video recorders) are among the best options for modern CCTV systems and incorporate video processing and encoding capacity within the camera itself.
The footage is then streamed to the NVR for viewing or recording remotely – so for organisations with multiple sites or across a wide area; every camera can stream directly to the same remote device simultaneously.
It’s interesting to review the journey of CCTV and see how such a basic concept has grown into a responsive, digital system that combats crime and provides safety across our lives.
