Surveillance refers to the monitoring of behavior, activities, or other changing information for the purpose of influencing, managing, directing, or protecting people. It encompasses a wide range of methods, including electronic monitoring, such as closed-circuit television (CCTV), audio recording, and computer monitoring, as well as physical tracking and data collection. The term originates from the French word surveiller, meaning "to watch over." In Hebrew, surveillance is translated as מִפְקָד (mifkad) or פיקוח (pikuch). In Spanish, it is vigilancia, in Arabic, مراقبة (murāqaba), and in German, Überwachung. Surveillance is used by governments, organizations, and corporations for various purposes, including security, crime prevention, and behavioral analysis. It has become increasingly prevalent in the digital age, with advancements in technology enabling more sophisticated and pervasive monitoring techniques. However, the use of surveillance raises significant privacy and ethical concerns, as it can infringe on individual rights and freedoms if not properly regulated and controlled.
