What is a video surveillance system?

A video surveillance system is an advanced network of interconnected cameras, monitors, and recorders that aim to protect the building from any illegal intrusion. Video surveillance systems are usually designed to work 24/7 without significant risks or interruption. The video surveillance system is an umbrella term that may encompass many different kinds of security systems, including wired systems, wireless systems, and analog or digital CCTV systems. Other elements of surveillance that might be included in this term are wireless cameras, smart doorbells, spy cameras, alarm systems, and even smart homes.

Video surveillance systems are designed for all kinds of buildings, including businesses, government establishments, apartment buildings, and private houses.

What is CCTV? Are CCTV and video surveillance system the same thing?

CCTV is a video surveillance system that is translated as closed-circuit television. The terms CCTV and video surveillance system basically have the same meaning, but the term "surveillance system" mostly describes the purpose of technology, while CCTV, or closed-circuit television, describes the type of technology that is used in video surveillance systems. CCTV is by far the most popular technology used in video surveillance systems; however, it is not the only one. IP cameras that are connected via the Internet are not usually referred to as CCTV, though a broader term, "digital CCTV system," is still possible.

Analog vs. Digital Video Surveillance Systems: What Is The Difference?

Both analog and digital video surveillance systems are still widely used in companies, government entities, and households alike. 

CCTV analog video surveillance systems have existed on the market for a long time. In an analog surveillance system, the video captured by the camera is recorded with a DVR recorder that is connected to the monitor. The video is broadcasted via the internal network without the need for internet access to be established.

In a digital video surveillance system, a digital camera or an IP camera records the video through a digital video recorder. The data is stored online, and one can access it remotely while not on the premises.

The use of digital surveillance systems usually results in higher video quality. Moreover, such systems use less wiring, are more secure, and provide a bigger coverage area. It is possible for digital surveillance systems to operate via wireless networks. However, when choosing a digital surveillance system, you should be prepared for the fact that it is more expensive than the analog system, requires high network bandwidth, more storage, and is more difficult to set up.

Analog CCTV systems are relatively inexpensive, simple, and have low bandwidth requirements. What is more, there are more designs of analog systems available on the market, which makes it easier to choose an ideal one for your respective needs. At the same time, analog CCTV systems have lower image quality and smaller coverage areas.
