Surveillance refers to the monitoring of behavior, activities, or information for the purpose of gathering data, ensuring security, or detecting criminal activity. It can involve various methods, including physical observation, the use of cameras, electronic data collection, and other tools designed to track individuals or groups. Surveillance is commonly employed by government agencies, law enforcement, and private entities for reasons such as crime prevention, public safety, and intelligence gathering. It raises important ethical and privacy concerns regarding the extent and methods of monitoring individuals, as well as the potential for abuse of power and violations of civil liberties.
