CCTV stands for closed-circuit television. A CCTV system is a network of cameras and other devices that are used to monitor and record activity in a particular area or building. The cameras are connected to a recording device, such as a digital video recorder (DVR) or a network video recorder (NVR), which captures and stores the footage.

CCTV systems are used for a variety of purposes, such as security surveillance, traffic monitoring, and industrial process control. They are commonly used in public spaces such as airports, train stations, shopping malls, and sports stadiums to monitor and record activity for security purposes. They are also used in industrial and manufacturing settings to monitor production lines and ensure safety.

CCTV systems can be either analog or digital. Analog systems use older technology and require physical wires to transmit the video signal. Digital systems are more modern and use IP (Internet Protocol) technology to transmit the video signal over a network. Digital systems are generally more flexible and scalable, making them a popular choice for many applications.

CCTV systems can be an important tool for security and safety, providing a visual record of activity that can be used to investigate incidents and deter criminal activity. However, it is important to ensure that CCTV systems are used in a responsible and ethical manner, and that privacy concerns are considered.
