Closed-circuit television system (CCTV), also known as video surveillance, is commonly used for security monitoring. It records the scene with a digital video recorder (DVR) or a network video recorder (NVR). Video footage is a reliable witness which reflects the real-time crime scene that is conducive to further investigation.
The usage of CCTV has gone beyond merely security concerns. A growing number of video analytics (e.g. AI applications) has been integrated into CCTV systems, bringing it to a new era. It becomes a superb management tool for business analysis and operation management. Besides the existing wide range of usage including security monitoring, production process monitoring in
factories, traffic flow monitoring in smart cities, head-counting in shopping arcades, fire detection in remote areas, CCTV is also used to fight diseases such as the COVID-19 pandemic recently. Through sensible network connections, users can monitor any activities from anywhere anytime.
By incorporating a video management system (VMS), the power of CCTV is far boosted, which is not what a system with DVR or NVR can be compared to. Video analytics are common in a VMS. Any quick search of a particular person with specific clothing items, gender, gestures, facial features, style, you name it, can be easily traced. As a matter of fact, VMS is also an ideal platform for integration with various security systems, for instance burglar alarm systems and access control systems.
