CCTV systems, or Closed-Circuit Television systems, are surveillance setups that use cameras to monitor and record activities in specific areas. These systems transmit video footage to a limited number of monitors, allowing for real-time observation and recording. They are commonly used in places like businesses, banks, and public spaces to enhance security and deter crime. The components of a CCTV system typically include cameras, monitors, and recording devices. Cameras can be fixed or movable, capturing footage in various lighting conditions. The recorded video can be stored for later review, helping authorities investigate incidents and maintain safety in monitored locations.
