Surveillance Cameras vs Security Cameras: What’s the Difference?

Surveillance vs Security Cameras

The terms “surveillance cameras” and “security cameras” are often used interchangeably, and in everyday conversation, they generally refer to the same concept: cameras used for security purposes. However, in some contexts, people draw distinctions between them. In this section, we’ll clarify any differences and similarities between surveillance cameras and security cameras, so you know exactly what each term implies. We’ll keep it straightforward and myth-bust any confusion.

Understanding the Terms

Let’s start by breaking down the words:

  • Surveillance Cameras: “Surveillance” comes from the French word surveiller, meaning “to watch over.” So, surveillance cameras literally mean cameras for watching over something. The term often implies continuous monitoring. For example, you might hear about “surveillance footage” on the news, which usually refers to video from cameras in public places or businesses that is recorded continuously and used to surveil (keep an eye on) an area for any wrongdoing. Surveillance has a slightly broader vibe – it can be passive or active, and sometimes people think of it as something done by authorities (like government surveillance cameras in a city).
  • Security Cameras: This term directly ties the cameras to the purpose of security – protecting property or people. Security cameras are those installed as part of a security system to detect or deter criminal behavior. The phrase is often used for cameras installed by private entities (home security cameras, business security cameras). It’s basically highlighting that the camera’s role is to provide security.

In practice, there’s a huge overlap. Both surveillance and security cameras are cameras used to capture video for safety and protection reasons. Many manufacturers even use the terms interchangeably in product descriptions.

However, here are a couple of nuanced differences some people point out:

  1. Active Monitoring vs Passive Recording: Some might say “surveillance cameras” are part of an active surveillance system, e.g., watched in real-time by guards or law enforcement (think of a casino’s camera room or city CCTV monitored by police). Whereas “security cameras” at a home or shop usually aren’t watched live continuously; they record and only get checked when there’s an issue (more passive). This isn’t a hard rule, just a connotation – you could actively monitor your home security cams, and conversely, a business might passively just record 24/7 (which could be called surveillance recording). But if someone wants to split hairs: surveillance cam implies Big Brother is watching live, security cam implies it’s there to review if something happens, and mainly to scare off intruders.

  2. Public vs Private Context: Surveillance cameras are often referenced in public or commercial context – government or large-scale systems (“city-wide surveillance,” “store surveillance footage”). Security cameras often reference home or small business use (“we put up security cameras around the house”). It’s basically perspective: If you feel watched by someone else, you might call them surveillance cameras. If you yourself put them up to guard your stuff, you might call them security cameras. It’s somewhat psychological. For example, an employee might say “the office has surveillance cameras watching us,” focusing on the being-watched aspect. The employer might say “we installed security cameras to protect the office,” focusing on the security aspect. Technically, they’re the same cameras. The difference is viewpoint and purpose emphasis.

  3. Overt vs Covert: Surveillance can sometimes imply a covert element (like hidden cameras or long-term observation, as in surveillance operations by police). Security cameras are typically overt (out in the open, meant to deter because people see them). So one might say covert cameras used by law enforcement or private investigators are surveillance devices, not really called security cameras since they aren’t deterring – they’re purely collecting evidence. Meanwhile, that dome camera on the ceiling of a 7-Eleven is a security camera (also providing surveillance, but its presence is obvious). Again, this is not a strict dictionary difference, but how people sometimes differentiate usage.

Given these subtle differences:

  • All security cameras provide surveillance (they survey/watch).
  • Not all surveillance cameras are for security (some could be for traffic monitoring, or wildlife observation – those aren’t “security” but they are surveillance cameras).
  • In marketing, you’ll see “CCTV” (closed-circuit television) used as well, which is basically the same as security/surveillance cameras but typically analog systems.

Functional Differences (Really, There Aren’t Many)

From a hardware perspective, there’s no fundamental difference. A camera is a camera. One labeled “surveillance camera” vs one labeled “security camera” could be identical in specs: resolution, night vision, etc. You won’t find like, “surveillance cameras have feature X that security ones don’t” – they’re overlapping tech.

If anything, maybe:

  • Surveillance system might imply a larger system with many cameras networked together, possibly professionally monitored or used in large enterprises.
  • Security camera system might imply a smaller setup, like 4-8 cameras for a home or small business.

But that’s not a rule. People might say “my home surveillance system” or “the mall’s security cameras” oppositely too.

So functionally, you can treat the terms as synonyms for most purposes. If a store sells “surveillance cameras,” those are fine for your home security. If another sells “security camera kit,” it can be used for general surveillance of whatever you need to monitor.

Usage in Sentences (Examples to Illustrate Context Difference)

  • “The surveillance cameras in the city center are monitored by the police department.” (Emphasizes official watching).
  • “I installed security cameras around my house.” (Emphasizes personal/home protection).
  • “Security footage” and “surveillance footage” essentially mean recorded video from security cameras; both phrases are used in news. Sometimes media say “surveillance video” especially when talking about a suspect caught on a camera in a public place or store. If it’s from a private home, they might say “home security camera captured…”.
  • Businesses often have a “Security Camera Policy” or sign, but bigger places might refer to the network as their “video surveillance system.”

Essentially, you shouldn’t get too hung up on wording. When asking for or discussing cameras, nearly everyone will understand either term to mean cameras used for security monitoring.

Public Perception Differences

One interesting point: “Surveillance” has a bit of a big brother or privacy-invading connotation sometimes, whereas “security” sounds more benign/positive. If someone says “you’re under surveillance,” that feels heavy. If they say “for your security, there are cameras,” that feels more reassuring. So, companies and authorities might choose phrasing based on the message they want to send.

  • A mall sign might say “These premises are under video surveillance for security purposes.” It uses both terms to cover all bases.
  • A homeowner might tell a contractor, “just so you know, we have security cameras outside.”
  • Meanwhile, a privacy advocate might complain about “the proliferation of surveillance cameras infringing on privacy.”

So in terms of role:

  • Both types of cameras deter bad behavior and provide evidence.
  • A surveillance camera system might imply a continuous, wide-reaching eye (like a city’s network of street cameras – they surveil the public).
  • A security camera is usually directly tied to an alarm or security plan for a specific property.

Summing Up the Difference

If we have to draw a line:

  • Security Camera: Typically refers to a camera that is part of a security strategy, often installed on private property, intended to protect that property from intrusions or misconduct. The term is common in everyday usage for homes and businesses. It’s a subset of surveillance cameras geared towards security of a location.
  • Surveillance Camera: A broader term for any camera used to observe/record an area. All security cameras are surveillance cameras, but surveillance camera could also include things like a hidden camera a detective sets up (not exactly a “security” camera since it’s not securing property at that moment, but it is surveilling). Or those cameras on highways monitoring traffic flow – those surveil traffic but are not for “security” per se (though they can help in law enforcement for accidents, etc.).

So you could say: security cameras are for security; surveillance cameras can be for security or monitoring or intelligence gathering, etc.

In practical home or office use, there’s no difference – it’s more about semantics.

Which Term to Use?

If you’re setting up cameras at home or a small business, calling them “security cameras” is most common. If you’re talking about a network of cameras in a city or a concept of watching people, “surveillance” might be used more.

Some vendors brand themselves as “video surveillance solutions” because it sounds a bit more professional/industrial than “security camera kit,” but they mean largely the same hardware.

In conversation, if someone says they have surveillance cameras at home, they mean security cameras. If a police officer says they’re going to check the neighborhood for surveillance cameras that might have caught something, they include any camera – home security cams, doorbell cams, business CCTV – basically any footage from the area.

So in effect, there’s no technical difference, mostly context and nuance in meaning:

  • Surveillance = monitoring (could be live or recorded).
  • Security = intended to help secure/protect.

Conclusion

Surveillance cameras vs security cameras: The difference largely boils down to wording and context rather than any actual function. Both are cameras used to monitor and record areas for safety and security reasons.

If pressed:

  • Think of surveillance as the act (the overall practice of observing), and security as the purpose (to secure assets).
  • Surveillance cameras might be thought of as part of a broader surveillance system (possibly monitored in real-time by authorities or security personnel).
  • Security cameras are typically what homeowners and businesses install to catch burglars or vandals, often checked only when needed and aimed at securing one’s property.

In day-to-day use, you don’t need to stress the difference. If you’re shopping, manufacturers might use “surveillance system” in specs, but it works for security. If you’re writing a report or something, you might use “surveillance” to sound formal.

Ultimately, both keep watch to enhance security. The key is that whatever you call them, these cameras serve as deterrents and provide valuable evidence, contributing to overall security. So feel free to use either term – just know that some audiences might perceive a slight difference in emphasis. But in securing your home or business, both surveillance and security cameras are on your side doing the same job: keeping an eye on things when you can’t.
