CCTV (Closed Circuit Television) refers to a system of video cameras used to monitor and record activities in specific areas, such as businesses, public spaces, or homes. Unlike broadcast television, CCTV footage is transmitted to a limited set of monitors or recording devices, making it a popular choice for security and surveillance. However, if these systems are compromised by hackers, they can provide unauthorized individuals with real-time access to visual information, posing significant privacy and security risks.
