Where there is no on-site observer, a video surveillance system provides visual surveillance. A video surveillance system (VSS) is made up of a camera, a recording/control device, and an output interface, such as a monitor. Storage, encoders, an interface, and administration software are also included. Surveillance can also be done in real-time or can be analyzed, saved, and repeated as often as needed. This involves remote surveillance using technology devices like CCTV cameras. Peace enforcement agencies rely on video surveillance to preserve law and order, monitor and spot threats and prevent criminal activity. Furthermore, with the video surveillance-as-a-service (VSaaS) delivery model, video management, storage, and analytics solutions are housed centrally in cloud computing and may be accessible through the internet.
