What is the meaning of CCTV?

CCTV, also known as closed-circuit television or video surveillance, is privately transmitted video which is generally used for the purpose of security or surveillance for a particular property or area. CCTV is heavily reliant on the specific placement of cameras to ensure maximum observation and clarity, which is then streamed to monitors and can be recorded for future use. A basic CCTV system comprises the camera itself, the lens, a monitor and a recording device.

CCTV Camera History

Did you know, the first mechanical CCTV system was developed in 1927 by Russain physicist Leon Theremin and was capable of transmitting images over shortwave radio. With only a couple hundred lines of resolution, It was extremely low rez by today’s standards but good enough to be used in the courtyard of the Moscow Kremlin to monitor approaching visitors.

About CCTV Camera Systems

The biggest use case for a CCTV camera system is to serve as a deterrent to inappropriate and illegal behaviour. Having a visible CCTV system is one of the most functional methods in preventing and reducing crime wherever one is installed. Modern CCTV systems do not always have to rely on human observation in order to function as methods like motion detection can be used which then can be pinged to the owner of the CCTV system.

What is the difference between a CCTV camera, a security camera and my Webcam?

A CCTV camera system is essentially a self-contained surveillance system that can be analog or digital which transmits a private feed of camera input to a receiving station. Traditional Analog CCTV devices were transmitted via coaxial or UTP cabling making them self contained by default.

Modern CCTV systems are no longer analog and are very similar to modern day IP cameras. In order to make them self contained and secure a number of security protocols can be used including P2P networking and putting them on a Virtual Private Network (VPN) Many dedicated digital CCTV devices are setup out of the box to do exactly this.

The typical webcam and the home Security camera solutions you find at your local tech stores are essentially just Internet Protocol (IP) cameras which utilise either wireless or ethernet networking and are mostly used on home and business networks for chat and video conferencing. Software can mimic the functionality of a dedicated CCTV system using these cameras but generally do not offer the security and features of a dedicated CCTV system.
