Electronic surveillance, also known as electronic surveillance, is the practice of using electronic devices to monitor and record activity or communications. This approach has gained prominence due to the rapid development of digital technology, which enables real-time collection of data and information. From closed-circuit television cameras (CCTV) in public places to tapped phone lines, electronic surveillance has changed the way authorities monitor, investigate and prevent criminal activity.

Benefits Of Electronic Surveillance
One of the major benefits of electronic surveillance is its role in enhancing public safety. Surveillance cameras are increasingly being installed in cities, airports and shopping malls to act as a deterrent and help authorities identify and apprehend criminals. These cameras help in the prevention and investigation of crimes, serve as evidence in court proceedings and contribute to the overall maintenance of law and order. In many cases, the mere presence of surveillance cameras can act as a psychological barrier, greatly reducing criminal activity.
Additionally, electronic surveillance has proven to play an important role in counterterrorism efforts. Governments around the world utilize advanced surveillance systems to monitor potential threats and gather intelligence about individuals or groups involved in terrorism. These measures help prevent terrorist attacks, disrupt terrorist networks, and keep citizens safe. Electronic surveillance technology has played an important role in identifying and apprehending individuals involved in the planning and execution of terrorist acts.
Another important aspect of electronic surveillance is its impact on individual privacy. While surveillance technology has undoubtedly enhanced security, there are also concerns about invasions of privacy. Critics argue that the widespread use of surveillance cameras and other electronic surveillance methods violates the right to privacy, often subjecting innocent people to constant surveillance. Striking a balance between security and privacy is critical to ensuring that surveillance measures do not infringe on civil liberties.
