What Does CCTV Stand For and When Was It Invented?
CCTV stands for Closed-Circuit Television. It is a system comprised of cameras and monitors. It is designed to send video signals in a closed loop.
Unlike broadcast television, where signals are sent to anyone with a receiver, CCTV is private and secure, a feature that has made it indispensable for crime prevention, public safety, and surveillance.
CCTV cameras are now standard in offices, shops, homes, and public spaces, providing the foundation for both professional security work and everyday monitoring.
But when was CCTV invented, and how did it evolve into the powerful tool it is today?
Let’s briefly examine its origins before exploring the history of CCTV.
When Was CCTV Invented?
The history of CCTV dates back to the 1920s, when rudimentary mechanical television systems were experimented with for monitoring industrial processes.
The first recognisable CCTV system, however, was developed in 1942 by German engineer Walter Bruch, during World War II, to observe V-2 rocket launches.
Shortly after, in the 1940s and 50s, CCTV technology began to spread, with early use in the United States for industrial monitoring.
CCTV was first introduced in the UK in the late 1950s, primarily for crowd surveillance during significant events.
Below is a timeline showing the evolution of CCTV over the decades.
CCTV Timeline: Key Milestones

1920 | Experimental mechanical television systems used in industrial settings. |
1942 | Walter Bruch designed the first proper CCTV to monitor V-2 rocket launches. |
1949 | American company Vericon markets CCTV systems commercially in the U.S. |
1960s | CCTV first appeared in the UK for crowd monitoring during public events. |
1960s-70s | CCTV becomes more widely used in banks, shops, and public spaces. |
1980s | The introduction of video cassette recorders (VCRs) made recording feasible. |
1990s | Digital video recorders (DVRs) replaced analogue systems, improving storage and playback capabilities. |
2000s–present | CCTV is integrated with the internet, AI, facial recognition, and cloud storage. |
These milestones highlight how CCTV transitioned from a niche technology to a mainstream security tool.
In the UK, the Security Industry Authority (SIA) – UK’s regulatory body for private security, emphasises the crucial role that CCTV plays in protecting the public, retail environments, and critical infrastructure.
Today, CCTV has become a vital tool for retail security, enabling licensed operators to monitor retail spaces, public areas, and private properties.
History of CCTV: When Were Security Cameras Invented & When Was It First Used?
The history of CCTV begins during one of the most turbulent periods in modern history: World War II.
As the need for controlled observation grew, engineers and scientists developed the first security cameras. This marked the point when CCTV started to be used as a real tool to keep an eye on things, and not just as a test.
In 1942, German engineer Walter Bruch designed and implemented a closed-circuit camera system to monitor V-2 rocket launches safely and discreetly. This was the first documented use of CCTV for an operational purpose, ensuring that sensitive military activities could be observed without risk to personnel.
After the war, this technology crossed the Atlantic and began to find new uses.
By 1949, CCTV technology was commercially available in the United States.
American banks first used security cameras to watch customers and detect potential robberies.
Soon after that, industrial facilities, including factories, laboratories, and power plants, began to utilise CCTV to enhance safety, laying the groundwork for its broader adoption in public and commercial spaces.
These early establishments in the history of CCTV set the stage for its global adoption. What began as a wartime innovation evolved into a trusted tool for safety, control, and security.
The first use of CCTV during the war and its post-war expansion into American industry marked the moment when security cameras were truly invented as a field, bridging military, industrial, and eventually public life.
CCTV in the UK: Growth & Adoption
When CCTV advanced from military and industrial applications into public life, the UK quickly recognised its potential.
It was introduced in the UK in the 1950s, initially to monitor crowds at big events, but soon became part of urban security.
Over the decades, its role expanded from event surveillance to traffic control, crime prevention, and eventually, everyday monitoring in public and private spaces.
Let’s look at the growth of CCTV in the UK security sector:
- 1953 CCTV was first used in the UK to monitor the crowd at Queen Elizabeth II’s coronation. An early use of CCTV for crowd management.
- 1961 London Transport installed cameras in one of its train stations to improve passenger safety and deter crime, a first at the time.
- 1964 Liverpool police conducted an experiment by deploying four hidden cameras on the streets – one of the first uses of CCTV for urban crime prevention.
- 1970s and 1980s as technology became more affordable and reliable, local councils began to roll out CCTV in car parks, housing estates, and shopping centres.
- 1990s CCTV grew the most in the UK, it became part of urban infrastructure due to government funding to reduce crime in town centres.
These milestones show how the UK adopted CCTV to address the growing security needs.
