In 1927, Russian inventor Leon Theremin developed what is considered the first CCTV system. It was used to watch visitors at the Kremlin in Moscow. German engineer Walter Bruch also created another notable system.
3. What is the purpose of closed-circuit television?
CCTV is primarily used for surveillance and security purposes. It is a TV system in which signals are not publicly distributed but rather monitored.
4. What are two benefits of CCTV?
CCTV systems have various benefits, including crime prevention, reduction of security costs, deterring vandalism, providing camera footage for evidence, handling disputes, monitoring staff, enhancing customer service, and ensuring visibility of entire business premises.

Why do you need a closed circuit for current
A closed circuit of conductive material provides a path for electrons to continuously flow. The charges are propelled by an electric field. We need a source of electric potential (voltage), which pushes electrons from a point of low potential energy to higher potential energy.
Is a closed circuit good or bad
A closed circuit will also provide a complete path for the electric current, meaning that electrons can flow smoothly from one end to the other. This allows for voltage and power to be produced across the load terminals as long as it is connected in the right way.
Why closed-circuit television CCTV must be installed in every classroom given your views either for or against this statement
Installation of CCTV should be mandatory in every classroom not only from the security point of view but it will also help to monitor the activities of the students as well the teachers during the lectures, breaks and otherwise. Any kind of mishap can be easily monitored and prevented by CCTV surveillance.
