When Was the Security Camera Invented

If you’ve ever Googled “when was the security camera invented,” you’ve probably noticed something odd: different pages give different years. One says the 1920s. Another points to June 1927. Others mention 1949, 1966, or 1969. The short answer is that “security camera” can mean different things—like early closed-circuit TV (CCTV) versus a home security system designed for everyday use. Here’s how those dates usually fit into the timeline, and what each one is likely referring to.

Early surveillance before “security cameras” (1920s Russia/Kremlin surveillance)

Some origin stories start in the 1920s, tied to surveillance connected to the Kremlin in Russia. In this telling, the point isn’t a specific “camera” like the ones we think of today. It’s that surveillance setups were already being used in a controlled, monitored way—something later people group under the broader history of security camera technology.

What matters for your timeline: this early date is usually about early surveillance, not about the “modern security camera” design or home use. So if you see “1920s Russia” listed as the origin, read it as “early surveillance system,” not “the first home camera.”

June 1927: mechanical CCTV developed by Leon Theremin

One of the more specific claims is June 1927, when a mechanical CCTV system was developed by Russian physicist Leon Theremin.

This matters because of what CCTV (closed-circuit television) means. It’s TV for a closed system, where signals go to a limited set of monitors instead of being broadcast to the public. In that sense, the 1927 date is often treated as the point where “CCTV for surveillance” becomes a clearly named invention claim.

So for the “when was it invented” question, June 1927 fits best as:

• the start of CCTV-style surveillance (specifically a mechanical CCTV system),
• connected to a named person and a specific month, not just a vague “early era.”

1949: the first rudimentary commercial CCTV security cameras (and the recording limitation)

Next comes 1949, which appears as the first rudimentary commercial CCTV security cameras, made by the American company Vericon.

This is another place where the snippets change what “invention” means. These cameras are described as rudimentary, and—crucially—they still couldn’t record.

That detail is the main limitation. Watching a live feed is different from storing footage you can review later. So when a page points to 1949 as the invention moment, it often refers to:

• the early commercial availability of CCTV cameras,
• along with the fact that recording wasn’t part of the system yet.

In short, 1949 fits as:

• early commercial, CCTV-style security cameras,
• with the limitation that they couldn’t record.

1966: the first modern security camera claim (Marie Van Brittan Brown and system design)

Now the timeline jumps to 1966, which is often labeled “modern.”

The claim here is that the first modern security camera was invented in 1966 by Marie Van Brittan Brown and her husband in New York.

This date shows up because sources often separate:

• early CCTV systems (like the 1920s and 1949 claims),

from

• a more “modern” approach to security cameras, the kind of system design later home security ideas are built on.

So the 1966 claim isn’t just “someone made a device that shows an image.” It’s treated as a step toward security camera system design.

1969: the first functioning home security camera claim (Marie Van Brittan Brown)

A closely related home-focused claim is 1969, also tied to Marie Van Brittan Brown.

In this version, it’s described as the first functioning security camera/home security system.

That difference—1966 is the “modern security camera” claim, while 1969 is the first home setup that actually functioned—is likely why people argue over the invention dates. One year is about the design concept, and the next is about what’s framed as working as a home security system.

If you’re seeing both years, it helps to treat them as two steps:

• 1966: modern security camera invention claim
• 1969: functioning home security system/camera claim

When were security cameras first used in homes?

Based on the snippets provided, the clearest home-use answer ties to Marie Van Brittan Brown’s work in the 1960s:

• one claim places the first modern security camera in 1966
• another places the first functioning home security system/camera in 1969

So if what you mean is “when did home security cameras show up,” the supported timeline points to the late 1960s, not the earlier CCTV-era dates. The snippets mention early CCTV and commercial cameras in earlier years, but they don’t spell out home use for the 1920s or 1949. The home-specific claims are the 1966/1969 ones.

Did security cameras exist in the 70's?

The snippets you provided don’t directly say “yes” for the 1970s, and they don’t provide evidence like “they were used widely in the 70s.”

What they do support is this: the invention claims come in 1966 and 1969, so it’s reasonable to say the technology existed afterward. But based on your evidence, the safest answer is:

• the snippets don’t directly confirm 1970s use, even though the invention claims are just before that decade.

Did security cameras exist in 1980?

Same issue: the snippets don’t explicitly confirm security cameras in 1980.

They mention:

• early CCTV (1920s, June 1927)
• commercial CCTV in 1949, with the note that cameras couldn’t record
• modern/functioning home security invention claims in 1966 and 1969

From what’s included here, there’s no direct confirmation that security cameras were specifically around in 1980. The timeline implies they existed earlier, but the snippets don’t make the 1980 claim outright.

Did security cameras exist in 2000?

The snippets also don’t give a direct yes-or-no for 2000.

They do provide key milestones:

• CCTV-style ideas in the earlier decades (1920s, 1927)
• commercial CCTV cameras by 1949 (still unable to record)
• modern and functioning home security claims in 1966 and 1969

But there’s no statement saying “in 2000, they definitely existed,” so this evidence doesn’t let us answer that decade directly.

When did security cameras become common (and what “common” likely means in practice)

This is tricky because “common” can mean different things:

• common in public buildings (banks, schools, hospitals)
• common in households
• common as a product you could buy and install
• common with recording, meaning footage is available later as evidence

One key point from the snippets is that in 1949, the earliest commercial CCTV cameras are described as still unable to record. If cameras can’t record, they may help with live monitoring, but they’re less likely to become everyday “evidence tools.” Recording capability is often part of why people want cameras enough to install them broadly. Since the snippets specifically call out the recording limitation in 1949, it also helps explain why widespread use might lag behind earlier invention dates.

As for home use and broader “commonness” after that, the evidence points to the late 1960s for functioning home security claims, but it doesn’t give a decade-by-decade adoption story. So when you ask “when did security cameras become common,” the supported way to frame it is:

• invented (or claimed): dates in the 1920s, 1927, 1949, 1966, 1969
• becoming common: likely later than those invention dates, especially if you mean homes and recorded footage, though the snippets don’t provide an exact “year it became common”

Quick answers (the PAA-style questions)

Here are the direct “timeline questions” people ask, using only what the snippets support:

• When were security cameras first used in homes?

The home-focused invention claims connect to 1966 (modern security camera) and 1969 (first functioning home security system/camera).

• Did security cameras exist in the 70's?

The snippets don’t explicitly confirm security cameras in the 1970s. They do show the relevant home-security invention claims in 1966 and 1969, which come right before the 70s.

• Did security cameras exist in 1980?

The snippets don’t explicitly confirm cameras in 1980.

• Did security cameras exist in 2000?

The snippets don’t explicitly confirm cameras in 2000.

If you’re buying a camera for home use (or picking a gift), those “common” and “in 1980/2000” questions are often less useful than the practical ones, like whether it records, how you review footage, and what you get for alerts.

If you’re shopping for a home camera as a parent…

A lot of parents don’t just want “a camera.” They want something that helps with real-life situations—package theft, door monitoring, checking on kids when you’re busy, or keeping an eye on routines you don’t want to micromanage.
