Difference Between CCTV & Surveillance Cameras

You've probably heard the terms "CCTV" and "surveillance cameras" thrown around, right? Well, they might seem pretty similar, but there are some differences between them. Don't worry, though! In this blog, we will discuss the difference between CCTV and surveillance cameras. So, let's jump into the blog.

What Are CCTV Cameras?

Closed-circuit television is the abbreviation for CCTV. These cameras are usually designed to be installed in a particular location, and they transmit the footage to a monitor or recording device. The footage is not accessible via the internet because they operate in a closed-loop system.

The traditional CCTV cameras convert captured images into electronic signals. The signal is transmitted by coaxial cable to a digital video recorder or monitor for storage or viewing. Modern CCTV systems are digital and transmit footage via a network to be viewed remotely or stored.

Key Features of CCTV Cameras

What Are Surveillance Cameras?

Surveillance, or Internet Protocol (IP), cameras are a broad category that includes a variety of video monitoring systems. They use digital technology to transmit video over a network. It allows remote monitoring and access from anywhere that has an internet connection.

Surveillance systems offer more capabilities than traditional CCTV systems. They can:

Differences Between CCTV and Surveillance Cameras

While both serve a similar purpose – monitoring and security – there are some key differences between CCTV and surveillance cameras. Here's a breakdown of some crucial factors:

Image Quality

In the past, CCTV cameras had a lower resolution than surveillance cameras. The gap between CCTV cameras and surveillance cameras has decreased with the advancement of technology. Modern CCTV systems also produce high-quality images. However, surveillance cameras have more options than ever, such as high definition (HD) or even 4K.

Power Supply

Traditional CCTV cameras rely on coaxial cable to transmit video. Surveillance cameras, on the other hand, can be powered by Power over Ethernet (PoE) which simplifies installation as both data and power are transmitted over one cable. Wireless options are also available, allowing for greater flexibility.


CCTV systems store the footage on-site on a DVR. It can be a disadvantage because the footage could be at risk if a DVR were to get damaged or stolen in a break-in. Surveillance camera storage is more flexible. The footage can be stored on a network NVR or uploaded to cloud storage, allowing for remote access and secure backup.


Costs of CCTV cameras and surveillance systems can vary depending on features, brand, and resolution. In general, CCTV systems are more affordable, especially when used for simple setups. Surveillance cameras with their advanced functionalities and features can provide a better value proposition in the long run despite an initial cost that may be higher.


CCTV cameras are used in private security applications such as the monitoring of homes, businesses, and restricted areas. Surveillance camera applications are more diverse, including monitoring public areas like parks and streets, monitoring traffic, and even monitoring the environment.

Can CCTV be used for surveillance?

Closed-circuit television is used widely for surveillance. They are used in a variety of settings including public and private spaces to monitor and ensure safety. The cameras record live footage that can be viewed in real time or later reviewed. This is a useful tool to deter and investigate potential security breaches. They can be used to monitor high-traffic zones, improve safety, and give property owners peace of mind.

Can CCTV Detect Crime?

CCTV systems are very effective at detecting crimes. Deterrents are used to deter criminals and reduce the likelihood of illegal activities. CCTV footage is a valuable tool for law enforcement to identify and arrest criminals. Surveillance cameras strategically placed can enhance security by constantly monitoring and recording suspicious activity.

Can Surveillance Cameras Be Hacked?

If not secured properly, surveillance cameras are vulnerable to hackers, just like other digital devices. Hackers can use outdated software or weak passwords to gain access to camera feeds. It is important to implement strong security measures such as creating unique, strong passwords and updating the software regularly. Selecting a reputable provider who places a high priority on cybersecurity will also protect your surveillance system against potential threats.
