When Was Security Camera Invented? A Brief History of Surveillance Technology

As we continue to rely on security cameras to keep us safe, it’s interesting to know when these devices were first invented. The history of security cameras dates back to the early 20th century when the first CCTV system was created in Germany in 1927 by Russian physicist and inventor Leon Theremin. The system included a manually-operated camera that scanned the area and transmitted it to a receiver.

However, it wasn’t until the 1960s when the first closed-circuit television (CCTV) system was invented in the United States. Marie Van Brittan Brown, a nurse from Queens, New York, invented a security system that consisted of four peepholes, a sliding camera, television monitors, and two-way microphones. These items created a closed-circuit television system for surveillance also known as CCTV. Brown’s invention was revolutionary and paved the way for the modern-day security camera systems that we use today.

Early History

When researching the history of security cameras, it’s important to look at the early days of surveillance technology. The first security cameras were developed long before the modern digital systems we use today.

Pre-20th Century

As far back as the 1700s, people were using basic forms of surveillance to monitor their property. One of the earliest known examples of this was the use of peepholes in doors, which allowed homeowners to see who was outside without opening the door.

By the late 1800s, the first closed-circuit television systems were being developed. These systems were used primarily for scientific research and were not yet being used for security purposes.

First Half of the 20th Century

It wasn’t until the early 1900s that security cameras began to be used in earnest. In 1927, Russian inventor Leon Theremin developed the first known video camera for surveillance purposes. This camera was used to monitor the entrance to the Moscow Kremlin.

Over the next few decades, security cameras continued to evolve. In the 1930s, German engineer Walter Burchard developed the first electrically powered security camera. This camera used a rotating mirror to reflect an image onto a film. Later, American engineer Harold Edgerton improved upon this design by adding a strobe light to freeze the image in place.

By the 1940s, security cameras were being used by the US and German militaries to monitor rocket tests from a safe distance. It wasn’t until the 1960s that security cameras began to be used in commercial applications, such as in banks and stores.

Modern Developments

Analog Cameras

After the invention of security cameras, analog cameras were the first type to be widely used. These cameras used analog signals to transmit video footage to a recording device, such as a VCR. Analog cameras were able to capture and record video footage, but the quality was not always clear and the footage could degrade over time. Additionally, analog cameras required a lot of wiring, making installation more difficult and expensive.

Digital Cameras

With the advent of digital technology, digital cameras quickly replaced analog cameras. Digital cameras use digital signals to transmit video footage to a recording device, such as a DVR. This technology provides much clearer footage and allows for remote access to the footage through the internet. Digital cameras are also easier to install and maintain, as they require less wiring and can be powered through a single cable.

One of the major advantages of digital cameras is that they can be integrated with other security systems, such as alarms and access control systems. This integration allows for a more comprehensive security system that can be monitored and controlled from a single location.

Another development in digital cameras is the use of IP cameras. IP cameras use the internet to transmit video footage, allowing for remote access and control from anywhere in the world. These cameras also provide higher resolution footage and can be integrated with other devices, such as sensors and alarms.

Overall, the development of digital cameras has greatly improved the quality and accessibility of security footage. With the integration of other security systems and the use of IP cameras, security systems have become more comprehensive and easier to manage.

Impact on Society

Security cameras have had a significant impact on society since their invention. In this section, we will discuss two important aspects of this impact: crime prevention and privacy concerns.

Crime Prevention

One of the most significant impacts of security cameras is their ability to prevent crime. By installing cameras in public places, businesses, and homes, we can deter criminals from committing crimes. Studies have shown that the presence of cameras can reduce crime rates in areas where they are installed.

Moreover, cameras can help identify criminals and provide evidence for law enforcement to prosecute them. This makes it easier to catch criminals and bring them to justice.

Privacy Concerns

While security cameras have many benefits, they also raise privacy concerns. Some people feel that cameras invade their privacy, especially when they are installed in private places like homes and bathrooms.

To address these concerns, laws have been put in place to regulate the use of security cameras. For example, in the United States, the Fourth Amendment protects citizens from unreasonable searches and seizures. This means that law enforcement must have a warrant to search private property or use surveillance cameras in private places.

Additionally, many businesses and organizations have policies in place to protect the privacy of their customers and employees. For example, they may only use cameras in public areas and not in private spaces like bathrooms or changing rooms.

Future of Security Cameras

As technology continues to advance, the future of security cameras is looking brighter than ever. With the development of smart cameras, we can expect to see even more advanced features that will make our lives easier and safer.

One of the biggest trends we’re seeing in security cameras is the integration of artificial intelligence (AI) and machine learning. This means that cameras will be able to learn and adapt to their surroundings, making them more effective at detecting threats and reducing false alarms. For example, AI-powered cameras can recognize the difference between a person and an animal, or between a car and a pedestrian, and adjust their response accordingly.

Another exciting development is the use of facial recognition technology in security cameras. While controversial, this technology has the potential to revolutionize security by making it easier to identify and track suspects. However, it’s important to ensure that this technology is used ethically and with proper oversight to prevent abuse.

Smart cameras are also becoming more interconnected with other smart devices in our homes, such as smart locks and smart speakers. This means that we can control our cameras with our voice or through our smartphones, and receive alerts when there is activity in our homes.

In addition, we can expect to see more cameras with higher resolution and better night vision capabilities, making it easier to capture clear footage even in low light conditions. And with the rise of 5G networks, we can expect faster and more reliable connections, allowing us to stream high-quality video in real-time.

Overall, the future of security cameras is looking bright, and we can expect to see even more advanced features and capabilities in the years to come.


Through our research, we have discovered that the invention of security cameras has a rich history that spans over a century. The earliest forms of security cameras were large and bulky, and they were not suitable for covert surveillance. However, advancements in technology have led to the development of smaller and more sophisticated cameras that can be used for both residential and commercial security purposes.

It is interesting to note that the first security cameras were not used for security purposes, but instead, they were used to monitor rocket tests during World War II. Today, security cameras are used in a wide range of applications, including traffic control, wildlife monitoring, and home security.

As technology continues to evolve, we can expect to see even more advanced security cameras with features like facial recognition and artificial intelligence. However, it is important to note that while security cameras can be an effective tool for deterring crime and enhancing security, they should always be used responsibly and in accordance with privacy laws and regulations.
