CCTV, or Closed-Circuit Television, is a system used for surveillance and security purposes. It involves the use of video cameras to transmit signals to a specific set of monitors. Unlike broadcast television, CCTV is not openly transmitted; instead, it operates over a closed circuit, hence the name. This technology is commonly used in various settings, including businesses, schools, and public spaces, to monitor activities and deter criminal behavior. CCTV systems can vary in complexity from simple setups with a few cameras to complex networks with multiple cameras and advanced features like motion detection and night vision. They play a crucial role in enhancing security and providing valuable evidence in case of incidents.Replace selected block t
