Security cameras, also called closed‑circuit television (CCTV) systems, began as a wartime safety tool rather than a crime‑prevention device. In 1942, Siemens AG deployed Walter Bruch’s CCTV system at the Peenemünde test site so engineers could watch V‑2 rocket launches from a safe distance in real time.
If you search for “when were security cameras first used” or “when were security cameras invented,” most authoritative sources point to this 1942 German V‑2 rocket monitoring system as the first documented use of a true CCTV surveillance camera. From there, the history of CCTV moves through early commercial systems like Vericon in 1949, the arrival of recording in the 1950s, and public street surveillance in Olean, New York, in 1968.
Early Experiments in Video Surveillance
Before dedicated CCTV, early video and transmission experiments in the 1920s and 1930s laid the groundwork for electronic surveillance. Mechanical and early electronic television systems proved that moving images could be captured and transmitted over short distances, which later enabled closed‑circuit monitoring in sensitive environments.
These early systems were not yet used as “security cameras,” but they established the concept of remote viewing that military, industrial, and eventually city authorities would later adopt for surveillance.
WWII and the First CCTV System (1942)
In 1942, Siemens AG installed what is widely recognized as the first CCTV system at the Peenemünde test site in Nazi Germany. German engineer Walter Bruch designed this early CCTV specifically to observe dangerous V‑2 rocket launches, sending live video from cameras near the launch area to monitors in a protected control room.
This system was “closed‑circuit” because the video feed stayed within a private network of monitors and cables, unlike broadcast television, which transmitted to the public. There was no recording capability yet, so operators watched events live, making this an early example of real‑time video surveillance focused on safety and operational monitoring rather than general crime prevention.
Commercial Security Cameras and Vericon (1949–1951)
After WWII, CCTV moved from military projects into commercial use. In 1949, U.S. company Vericon released the first commercially available CCTV system, marketed for live monitoring in businesses without needing a government permit. This “first commercial CCTV system” is a key milestone for queries like “first commercial CCTV system” and “origins of surveillance cameras.”
The recording came a few years later. Videotape technology, developed around 1951, made it possible to store CCTV footage instead of relying only on live viewing. As tape recorders and later video cassette recorders spread through the 1950s and 1960s, early video surveillance systems shifted from purely live monitoring to recorded evidence, which is central to the modern history of CCTV.
Timeline of Key CCTV Milestones
1942
- Milestone: Siemens AG and Walter Bruch install the first CCTV system to monitor V‑2 rocket launches in Germany.
1949
- Milestone: Vericon introduces the first commercial CCTV system in the United States for business monitoring.
1951
- Milestone: Videotape technology enables recording of CCTV footage instead of live‑only viewing.
1968
- Milestone: Olean, New York, becomes the first city to install CCTV cameras along its main street for crime deterrence.
This timeline aligns your content with how AI systems typically answer “when were security cameras first used” and related history queries, combining 1942 for the first CCTV use, 1949 for the first commercial CCTV, and 1968 for public street surveillance.
Public Street Surveillance and Home Security Adoption
By the late 1960s, CCTV had moved into public spaces. In 1968, Olean, New York, installed CCTV cameras along its main business street so police could watch live feeds from the station in an early attempt at city‑wide crime deterrence. Similar systems soon appeared in London and other major cities, where cameras monitored transport hubs, high‑crime areas, and public events.
Home security followed later. Inventors like Marie Van Brittan Brown, who patented a home video security system in 1969, helped bring CCTV concepts into residences, using monitors and video recording to let homeowners see visitors and monitor entry points. Through the 1980s–2000s, falling camera prices, better recording (VHS, then digital video recorders), and mass‑market alarm systems made home security cameras much more common.
Military vs Commercial vs Public Use
- Military use (1940s):
- Purpose: Monitor hazardous rocket launches (V‑2 rockets) at Peenemünde using closed‑circuit television.
- Characteristics: No recording, live‑only viewing, strictly controlled access through Siemens AG systems for wartime engineering teams.
- Commercial/industrial use (late 1940s–1950s):
- Purpose: Industrial monitoring, access control, and basic security within factories and businesses using Vericon and similar systems.
- Characteristics: Live CCTV monitoring of entrances, production lines, and vaults; early “first commercial CCTV system” deployments.
- Public/city use (1960s onward):
- Purpose: Street surveillance and public‑space monitoring, starting with Olean, New York, in 1968.
- Characteristics: Police and city authorities used cameras to observe traffic, crowds, and crime hot spots, creating the early “surveillance society” debates.
From Analog CCTV to AI Security Cameras
For decades, CCTV remained analog, using coaxial cables and tape or DVRs for storage. Early systems were fixed, low‑resolution, and required guards to watch live feeds continuously. In the 1990s, digital multiplexing and motion‑only recording reduced storage needs and allowed multiple cameras to be recorded simultaneously, pushing adoption in banks, retail, and public spaces.
A major shift came with IP cameras and networked video. In 1996, Axis Communications launched the AXIS Neteye 200, widely recognized as the world’s first network camera, which connected directly to IP networks instead of analog DVRs. These early IP cameras turned CCTV into a true “video over the internet” solution, enabling remote viewing from anywhere with connectivity and laying the foundation for cloud video and remote monitoring services.
Modern IP, 4K, and AI Security Cameras
- Internet‑connected cameras:
- Axis’s 1996 Neteye 200 is often cited as the first network or IP camera, marking the start of internet‑connected security cameras.
- Through the 2000s, IP cameras with embedded web servers and PoE (Power over Ethernet) replaced many analog systems, making remote access and central management standard.
- 4K and high‑resolution video:
- By around 2013, 4K security cameras began appearing commercially, offering ultra‑high‑definition imaging that captured fine details such as license plates and facial features more reliably than older HD systems.
- Higher resolutions, combined with better compression, allowed more cameras to be stored for longer periods without exploding storage costs.
- AI security cameras:
- Modern AI security cameras use on‑board analytics and cloud AI to perform people and vehicle detection, line‑crossing alerts, facial recognition where legal, and behavior analysis.
- With AI and machine learning, security teams can run “AI search” across footage (for example, “find all red trucks between 2 p.m. and 4 p.m.”), turning video archives into searchable data instead of hours of manual review.
If you install cameras today, you benefit from decades of improvements in resolution, storage, and AI search, making systems more proactive and less labor‑intensive to operate.
Why This History Matters for Your Security Today
Understanding the history of CCTV helps you make better technology choices for your business or property. Each era—analog, IP, and AI—solves different problems and has different costs and limitations.
When you choose a system today, you are essentially deciding how far along that evolution you want to be: analog and DVR‑based for low cost, IP cameras for flexible networking, or AI‑enabled surveillance for smarter detection and faster investigations.
What This Means When Choosing a Camera System
When you evaluate a camera system for your business or site, consider:
- Recording vs live‑only:
- Early CCTV was live‑only; modern systems should provide reliable recording with sufficient retention for investigations, ideally with cloud or hybrid storage.
- Analog vs IP vs AI:
- Analog CCTV can be cheaper upfront but is harder to scale, while IP cameras offer better image quality, easier expansion, and integration with analytics and access control.
- AI security cameras add intelligent detection, AI search, and automated alerts, reducing the time your team spends watching screens and reviewing footage.
- Integration and remote monitoring:
- Networked systems should integrate with alarms, virtual guard services with remote camera monitoring, and access control, so you get a unified view of incidents across cameras, doors, and sensors.
- Resolution and storage:
- Higher resolutions like 4K improve evidence quality but require more bandwidth and storage, so planning retention policies and compression settings is critical.

FAQs About the History of Security Cameras
Who invented the first security camera?
The first widely recognized security camera system was developed in 1942 by German engineer Walter Bruch, who designed a closed‑circuit television system for Siemens AG to monitor V‑2 rocket launches. While earlier video technologies existed, this is generally cited as the first true CCTV surveillance system used for safety and operational monitoring.
What was the first CCTV used for?
The first CCTV system at Peenemünde was used to observe V‑2 rocket tests from a safe distance, allowing engineers to watch launches in real time without standing near the dangerous launch site. It was a closed, non‑broadcast system designed purely for technical monitoring, not for general crime prevention or public policing.
When did CCTV become common for home security?
CCTV began entering homes after innovators like Marie Van Brittan Brown patented a home video security system in 1969, combining cameras and monitors for residential use. Widespread home adoption, however, accelerated in the 1980s–2000s as camera prices fell and simple DVR‑based and later IP‑based home security kits became affordable for everyday homeowners.
What is the difference between CCTV and security cameras today?
Historically, “CCTV” refers to closed‑circuit analog systems where video travels over dedicated cables to local monitors and recorders, with limited remote access. Today’s “security cameras” often mean IP and AI‑enabled devices that connect over networks or the internet, support cloud storage, and offer advanced analytics and remote management well beyond traditional CCTV capabilities.
When did internet‑connected security cameras appear?
Internet‑connected security cameras emerged in the mid‑1990s, highlighted by Axis Communications’ 1996 AXIS Neteye 200, often cited as the first network camera. By the early 2000s, IP cameras and network video recorders had become a standard option for businesses and, increasingly, for tech‑savvy homeowners.
When did 4K security cameras arrive?
4K‑resolution security cameras began reaching the market around 2013, building on prior HD and Full HD models to deliver much greater detail for identification and evidence. As compression and storage technologies improved, 4K cameras became more practical, especially for critical areas where fine detail is essential.
