A CCTV (Closed-Circuit Television) surveillance system is a setup where video cameras capture and transmit footage to monitors, allowing for live viewing and recording. The cameras are strategically placed to cover various areas and send their signals, either through cables or wirelessly, to a central monitoring station. Here, security personnel can watch the footage in real-time on monitors and control the system to switch views, zoom in, or review past recordings. The recorded footage is stored on digital video recorders (DVRs), network video recorders (NVRs), or cloud storage, enabling future retrieval. Some systems also have motion detection features that trigger alerts for enhanced security.
