The Evolution Of Surveillance Cameras: A Historical Perspective

Surveillance cameras have been around for a while, with the first recorded application of closed-circuit television (CCTV) dating back to 1942, when it was used to view the launch of V2 rockets in Germany. The technology was developed by German engineer Walter Bruch and soon picked up by the US government, which used it to observe nuclear bomb testing. By 1949, commercial CCTV systems were available in the US, and primitive security cameras soon became a force to be reckoned with in public and home security. The British police force utilized this technology in 1960 during a visit by the Thai royal family, and London Transport started installing CCTV cameras in train stations to bolster public safety. The first home security system was patented in 1969 by Marie Van Brittan Brown, a nurse from Queens, New York, who created the system to increase her sense of safety when left alone at home.

The first CCTV system was developed in the 1920s by Leon Theremin

The history of surveillance cameras can be traced back to the 1920s when the first closed-circuit television (CCTV) system was developed by Leon Theremin. Also known as Lev Termen, he was a Russian scientist and inventor, famous for creating the world's first electronic musical instrument, the theremin.

In the early 1920s, while working at the Physical Technical Institute in Petrograd, Theremin made a chance discovery. He noticed that when he hooked up audio circuits to an electrical device called an oscillator in a certain way, the oscillator produced an audible tone when he held his hands near it. Furthermore, he could change the tone by moving his hands back and forth. Intrigued by this, he soon delivered the first concert with his new electronic instrument, which he called the etherphone.

In 1925, Theremin travelled to Germany to sell the patent for his invention to the German firm Goldberg and Sons. Two years later, in 1927, he demonstrated moving images using a wireless television with 64 scan lines. This was the first functioning television apparatus in Russia.

Around this time, there is some evidence to suggest that Theremin also created a closed-circuit system using a camera and television in Stalin-era Soviet Russia. This system may have been the first surveillance camera, predating the next development by 15 years. However, the Kremlin quickly classified it, and details remain scarce.

In 1942, 15 years after Theremin possibly built his closed-circuit system, an engineer named Walter Bruch designed what is widely considered the world's first surveillance CCTV system. Bruch's system allowed Nazi scientists and military personnel to safely observe the launch of V-2 rockets at the Peenemunde Airfield.

The earliest CCTV security cameras available to the public were produced by the American company Vericon and appeared in 1949. These early cameras could not record and required constant monitoring. It wasn't until 1951, with the invention of the videotape recorder (VTR), that CCTV systems became more practical for security purposes.

The first publicly available CCTV system was sold by a US company in 1949

The history of surveillance cameras can be traced back to the 1920s, when Leon Theremin invented the first version of the security camera. This system was later installed at the entrance of the Moscow Kremlin to monitor visitors. However, the first publicly available CCTV system didn't come about until a few decades later.

In 1949, an American company called Vericon began selling the first commercial CCTV system. This marked a significant shift in the accessibility of security cameras, as they were no longer exclusive to the military. Businesses, banks, and private residences could now utilise this technology for surveillance purposes.

The introduction of the Vericon CCTV system paved the way for the widespread adoption of security cameras. No longer were they restricted to military applications; they were now being used to monitor streets, businesses, and even royal events. This development set the stage for the integration of CCTV into various aspects of daily life, from law enforcement to home security.

The impact of this technology was quickly felt around the world. By 1953, CCTV systems were used during the coronation of Queen Elizabeth II, and they were also implemented in New York City for security monitoring. This highlighted the growing recognition of CCTV as a valuable tool for safety and security in public spaces.

The evolution of CCTV continued with advancements in recording technology. Initially, CCTV systems relied solely on constant monitoring, as there was no way to record footage. However, with the introduction of reel-to-reel media and the development of videotape recorders, the ability to record and store surveillance footage became possible. This further enhanced the utility of CCTV systems and made them more desirable for various organisations.

The US played a pivotal role in the development and popularisation of CCTV technology. From its inception with Vericon to its integration in cities like New York, the US was at the forefront of making CCTV a mainstream surveillance solution. This set the stage for the extensive use of CCTV in various sectors, including law enforcement, retail, and home security.

The first home security system was invented by Marie Van Brittan Brown in 1966

The history of surveillance cameras can be traced back to the 1920s, when the first version of a security camera was invented by Leon Theremin. This early system was used to monitor the entrance of the Moscow Kremlin. However, the widespread use of surveillance cameras is a more recent phenomenon.

Among the pioneers of modern home security systems, Marie Van Brittan Brown stands out as a true innovator. In 1966, she invented the first home security system, which revolutionised the way people protected their homes and paved the way for the sophisticated systems we use today.

Marie Van Brittan Brown was driven by a desire to enhance her personal security. As a nurse, she often had to walk home late at night through a dangerous neighbourhood in Queens, New York City. The high crime rate and slow police response times motivated her to create a security system that would allow her to monitor her home and quickly call for help if needed.

Collaborating with her husband, Albert Brown, an electronics technician, she designed an integrated security system. The system featured multiple peepholes to accommodate people of different heights, a sliding surveillance camera, a monitor, and two-way audio. This enabled Brown to see and communicate with visitors, and if necessary, alert the police with the push of a button. Additionally, she could remotely unlock the door from a safe distance.

The Browns' security system was the first of its kind and laid the foundation for modern security features such as video monitoring, remote-controlled door locks, and instant messaging to security providers. The patent for their invention, titled "Home Security System Utilising Television Surveillance," was granted in 1969 and recognised by the National Scientists Committee.

Marie Van Brittan Brown's contributions to home security were significant, and her legacy continues to impact the world of security today. Her invention has been cited in numerous subsequent patent applications, demonstrating its enduring relevance and influence on the evolution of home security systems.

The first IP camera, the Axis NetEye 200, was released in 1996

The first internet protocol (IP) camera, the Axis NetEye 200, was released in 1996. This camera was the world's first internet camera and webserver in one. The Axis NetEye 200 was a palm-sized digital colour camera that could be installed as a self-contained web server. It required no additional system resources or file server involvement. Users could take snapshots using a browser and use them for any web application or send them over the internet.

Special software allowed the Axis NetEye 200 to function as a time-lapse recorder, saving images as JPEG files. The camera could record 1 fps in CIF and 1 frame every 17 seconds in 4CIF. The Axis NetEye 200 was the forefather of modern web and surveillance cameras.

The Axis NetEye 200 was also the first Internet of Things (IoT) device. Ulf Ridell from Informationssystem AB in Sweden designed an outdoor housing for the camera that included heating and a thermostat, a sun/rain roof, and a socket for the power supply. The camera was sold through the Axis website and became increasingly popular. One of the cameras was used to monitor the Davis Cup Finals in 1996.

The first video surveillance system was developed by Vericon in 1949

The history of surveillance cameras can be traced back to the 1920s, when the first version of a security camera was invented by Leon Theremin. This early system had a resolution of only 100 lines, resulting in a grainy and unclear picture. However, it was still used to monitor the entrance of the Moscow Kremlin. Fast forward to the 1940s, and we see the development of the first video surveillance system by Vericon in 1949. This system was the first to be commercially available to the public, marking a significant step towards making security cameras accessible to businesses, banks, and private residences.

The Vericon system was designed by CBS Laboratories and sold by Remington Rand in the United States. One of its key features was the use of cabled connections between the camera and monitor, eliminating the need for a government permit as it did not rely on over-the-air transmission. However, like its predecessors, the Vericon system still required constant monitoring as there was no way to record and store information at the time. This meant that someone had to be watching the monitor at all times, making it a time-consuming and inefficient process.

Despite this limitation, the introduction of the Vericon system represented a pivotal moment in the history of surveillance technology. It laid the foundation for future advancements, such as the development of reel-to-reel media and videotape recorders in the 1950s and 1970s, respectively, which finally enabled the recording of surveillance footage. These advancements, along with the increasing accessibility of CCTV systems, contributed to the spread of video surveillance worldwide.

By the 1970s, businesses in the United States had started using video surveillance technology to protect themselves from theft and other security concerns. The following decades saw continuous improvements in camera resolution and the emergence of IP cameras, which offered sharper images and data for analytics. Today, video surveillance systems have become an integral part of security for organizations, enabling them to protect assets, ensure public safety, and efficiently respond to emergencies.
