CCTV (Closed Circuit Television) is a closed system consisting of video cameras, display devices (monitors) and wired or wireless data networks that allow you to transfer images from video cameras to monitors.
The video surveillance systems, in addition to cameras and monitors, often include other devices, such as servers, disk storages, client computers that allow storing and processing video data. Also, video surveillance systems can be integrated with security systems and other information systems.
The video surveillance systems are designed to ensure security at protected sites, monitor personnel activities, keep track of production processes, etc.
