When Were Security Cameras Invented?

Security cameras, now a cornerstone of modern surveillance, have a rich history that spans over a century, evolving from rudimentary mechanical devices to sophisticated digital systems integrated with artificial intelligence. Their invention and development were driven by the need for security, monitoring, and documentation in various settings, from banks to homes. This comprehensive exploration traces the origins of security cameras, key milestones in their evolution, and their transformative impact on society, culminating in the advanced systems we use in 2025.

The Birth of Security Cameras: Early Beginnings

The concept of security cameras emerged in the early 20th century, though the technology was far from what we recognize today. The earliest precursor to security cameras can be traced to the 1920s, with the invention of closed-circuit television (CCTV) systems. These systems were designed to transmit video signals from a camera to a specific monitor, unlike broadcast television, which sent signals to a wide audience.

1927: The First CCTV Experiment

In 1927, Russian engineer Léon Theremin demonstrated one of the earliest closed-circuit television systems in the Soviet Union. His system used a mechanical scanning device to capture and transmit images to a receiver, primarily for experimental purposes. While not explicitly designed for security, this laid the groundwork for future surveillance technology by proving that images could be transmitted over a closed system.

Note: Theremin’s system was rudimentary, with low-resolution images and bulky equipment, making it impractical for widespread use.

1942: The First True Security Camera

The first documented use of a security camera occurred in 1942 in Nazi Germany, credited to engineer Walter Bruch. Bruch developed a CCTV system to monitor the launch of V-2 rockets at the Peenemünde research facility. The system used analog cameras to capture live footage, which was transmitted to a control room for real-time observation. This marked the first practical application of cameras for security purposes, specifically to ensure the safety and success of rocket launches by monitoring for malfunctions or intrusions.

Warning: Early CCTV systems were expensive and required dedicated wiring, limiting their use to high-security military and industrial applications.

Post-War Advancements: 1950s–1960s

After World War II, CCTV technology began to spread beyond military applications. The 1950s saw significant advancements in camera design and accessibility, driven by the growing need for security in commercial and public spaces.

1950s: Commercial Use in Banks and Stores

In the 1950s, banks and retail stores in the United States and Europe started adopting CCTV systems to deter theft and monitor transactions.
