CCTV (Closed Circuit Television) is a surveillance technology that uses video cameras to transmit a signal to a specific place, on a limited set of monitors. CCTV is widely used for surveillance and security purposes in public spaces, commercial buildings, and private residences.
CCTV systems typically consist of cameras, a recording device, and a monitoring system. The cameras capture video footage, which is then transmitted to a recording device such as a DVR (Digital Video Recorder) or NVR (Network Video Recorder). The recording device stores the footage for a specified period of time. The monitoring system allows users to view the live or recorded footage from the cameras, either on-site or remotely through an internet connection.
CCTV systems have come a long way in recent years, with the development of high-definition cameras, wireless transmission, and intelligent analytics software. These advances have made CCTV systems more effective and efficient at providing surveillance and security. It is important to ensure that CCTV systems are properly installed and maintained to ensure that they can provide effective surveillance and security for the intended purpose.
