What Is a CCTV Camera?
A CCTV camera (Closed-Circuit Television camera) is a video surveillance device that transmits footage to a limited set of monitors or recording devices. Unlike broadcast TV, CCTV systems are closed, meaning only authorized people can access the footage.
These cameras serve as a powerful tool in deterring theft, monitoring activity, and documenting incidents. From homes and retail stores to offices and public spaces, CCTV cameras are essential in modern security infrastructures.
How Does a CCTV Camera Work?
Understanding how a CCTV camera operates helps in choosing the right system:
- Capture: The camera lens captures video footage.
- Transmission: Footage is sent to a monitor, DVR (Digital Video Recorder), NVR (Network Video Recorder), or cloud storage.
- Recording: Data is stored for review.
- Monitoring: Footage can be monitored live or reviewed later.
Some systems are wired, while others are wireless. IP-based CCTV cameras allow remote access via mobile apps or browsers.
