What is CCTV primarily used for?

CCTV, or closed-circuit television, is primarily employed for monitoring and recording environments to enhance security measures. The system captures video footage that can be reviewed later or monitored in real-time, which is crucial for detecting and deterring criminal activity, ensuring safety, and documenting incidents for further investigation. This capability makes it an invaluable tool in various settings, such as businesses, public areas, and residential properties, where security is a primary concern.

While options like live streaming events and monitoring traffic patterns do involve surveillance technologies, they do not encompass the primary purpose of CCTV, which focuses specifically on security-related audio/visual recording. Conducting remote interviews with suspects falls outside the typical use case of CCTV, as it is not designed for interactive communication but rather for observation and evidence collection. Therefore, the choice relating to audio/visual recording for security purposes most accurately reflects the primary function of CCTV systems.
