Within a SOHO or enterprise environment, what is the primary security function of a closed-circuit television (CCTV) or other video-surveillance system?
Issue proximity cards to authorize personnel for facility entry
Monitor and record activity so security staff can view or review events
Detect abnormal heat levels and activate automatic fire-suppression systems
Automatically lock and unlock doors by validating badge credentials
CCTV/video-surveillance systems are deployed mainly to observe and record activity in real time or for later review. Continuous or motion-triggered recording can deter wrongdoing, allow live response, and provide admissible evidence during investigations. They do not directly control door hardware, manage credentials, or handle environmental sensing.
