CCTV ( Closed-Circuit Television ) is also known as video surveillance. The term “Closed-circuit” refers to the fact that the video footage is shared to a limited number of monitors from strategically placed cameras inside and/or outside a building. A CCTV system, therefore, refers to all components and aspects that make the system complete, such as the camera, monitors, cabling (network infrastructure if using IP), video storage and video management system.
