What technology is primarily used for surveillance in security operations?

Closed-circuit television (CCTV) systems are the primary technology used for surveillance in security operations because they provide continuous monitoring and recording of activities within a designated area. CCTV systems consist of cameras that transmit video footage to a specific set of monitors, allowing security personnel to observe real-time events and review recorded footage for any incidents. This technology is widely used in various settings such as retail environments, corporate offices, public spaces, and residential areas, making it a cornerstone of modern surveillance practices.

In addition to monitoring, CCTV systems often come with features like motion detection, remote access, and integration with alarm systems, enhancing their effectiveness in maintaining security. While other technologies such as motion sensors, drone surveillance, and smartphone applications can play supportive roles in security operations, none provide the comprehensive visual monitoring capabilities that CCTV systems offer. These characteristics solidify CCTV's role as the backbone of surveillance operations.
