A CCTV camera (Closed-Circuit Television camera) is a security device used to monitor, record, and protect people, property, and assets. Unlike regular television broadcasts, CCTV systems transmit video signals to a limited set of monitors or recording devices, making them ideal for surveillance and security purposes.
How Does a CCTV Camera Work?
A CCTV camera captures video footage and sends it to a DVR (Digital Video Recorder) or NVR (Network Video Recorder). The recorded footage can be viewed live or played back later through a monitor, computer, or mobile phone. Modern CCTV cameras also support remote viewing via mobile apps using the internet.
