CCTV stands for Closed Circuit Television. This is a system where the circuit is closed and all the elements are connected. CCTV security systems were originally developed to monitor commercial property and public spaces, but have adapted to home security systems in recent years.
CCTV and video surveillance systems is defined as the use of a video camera to transmit video to a limited set of monitors. This type of system differs from television to television in that the signal is not broadcast openly, it is only sent to a certain television monitor which is programmed or connected via cable to receive signals from this camera.
The most obvious and widely used method for video surveillance is security. These cameras are usually installed in parks, government offices, shopping centers, and other locations where the threat of illegal activity and theft is imminent.

However, many companies and institutions also use these cameras to monitor their employees so as not to become complacent at work. Can be used to monitor traffic. Used in sports stadiums to focus on the audience.
Early CCTV systems were a type of camera that was mounted on a television screen or monitor. This early system might not even have the ability to record what happened. Just take pictures in one place and view content in another place on the screen.
Now things have changed. Of course, commercial video surveillance systems have been more modern than this over the years, but now we have the opportunity to install and deploy state-of-the-art video surveillance systems in our homes and offices, significantly reducing costs and expanding facilities.
