Video surveillance involves the use of cameras to monitor and record activities in various environments, enhancing security and safety. Commonly deployed in public spaces, businesses, and residential areas, these systems help deter crime, gather evidence, and improve operational efficiency. Modern video surveillance often incorporates advanced technologies such as high-definition imaging, night vision, and remote access, allowing real-time monitoring and quick response to incidents. Proper implementation respects privacy regulations while providing a valuable tool for protecting assets and individuals.
