What Is CCTV And How Does It Work?


CCTV stands for Closed Circuit Television and it is what many people think of when they think of cameras for their security and protection. These cameras are used for a variety of purposes, including safety, security, employee monitoring, and peace of mind. What the cameras are and how they work are questions that many people have. Today we are going to answer those questions and more.

What Are CCTV Cameras?

Closed Circuit Television is a method of using cameras to monitor an area. The CCTV cameras utilize a local network of cables in order to transmit the visual data from the cameras. This data isn’t transmitted through the internet or any other outside source, hence the name, closed circuit. Unlike other cameras used for security and surveillance, CCTV cameras are kept separate.

Digital Vs. Analog CCTV

There are two major types of CCTV cameras, digital and analog. These terms refer to the type of signal that the cameras send. Analog CCTV cameras are the traditional version of CCTV. An analog signal has limited capabilities, such as not being able to reach full high-definition quality. On the other hand, some analog systems are cheaper and more secure than other camera methods.

Digital CCTV cameras on the other hand have more features. The cables and transmission methods are able to send out a fair amount of data. Including full high-definition quality and a multitude of extra features.

Why Do You Need CCTV Cameras?

CCTV is most commonly used to protect people and property. You are able to monitor your property in order to ensure that no one is trespassing and that anyone on the property is okay. If something does occur it is recorded on the digital video recorder and saved for later use. That footage can be used to apprehend and prosecute criminals. Even governments and law enforcement agencies have started to use CCTV cameras to ensure safety and security of public areas.

Some businesses use CCTV in order to monitor employees or production. That way they can ensure that everything is happening in an effective and productive manner. If something happens, they are able to identify the issue and correct it. CCTV can also be used to prevent corporate espionage or other issues.

One last major purpose for CCTV cameras is to ensure safety. You can monitor your home to ensure that your kids or pets are safe at all times. Especially if you have to leave them home alone. Businesses use these cameras for the same purpose. They monitor workplaces to ensure that any potential safety concern is noticed and addressed.

CCTV Features

Cameras that are used for surveillance need to be able to get everything you are concerned with on camera. To do this they come with a number of features. The exact features are dependent on the manufacturer and model. Here are some of the most common CCTV features:

  • HD Quality Video (Up to 4K)

  • Audio broadcasting

  • Analytic alarms
