What does the closed circuit mean in CCTV?

Closed Circuit Television, or CCTV, is a type of security system that is used to monitor and record activity in a given area. The closed circuit refers to the fact that these systems are not connected to the public television network. CCTV systems can be either analog or digital, and they are often used in conjunction with other security measures, such as alarms and locks.

There are many benefits to using CCTV systems. They can deter crime by providing a visual deterrent to potential criminals. They can also help to identify and apprehend criminals after a crime has been committed. CCTV footage can be used as evidence in court cases, and it can help police and prosecutors to build a case against a suspect.

However, there are also some drawbacks to using CCTV systems. They can invade privacy, as they may record images of people who are not committing any crime. They can also be costly to install and maintain. Additionally, if not properly monitored, they may miss criminal activity altogether.
