CCTV (Closed-Circuit Television)
Tl/DR: CCTV is a closed video system for monitoring and recording specific areas. It enhances security, deters crime, and allows real-time or recorded footage review.
Definition:
CCTV refers to a closed system of video cameras used to monitor and record activities in a specific area. Unlike broadcast television, the feed is transmitted to a limited set of monitors and devices, ensuring controlled access to the footage.
How It Works:
CCTV systems use cameras to capture video, which is transmitted to recording devices like DVRs (Digital Video Recorders) or NVRs (Network Video Recorders). The video can be viewed in real-time or stored for later review. Modern systems often incorporate IP cameras and remote monitoring capabilities via the internet.
