CCTV Camera for Indoor and Outdoor : Closed-Circuit Television (CCTV) refers to the use of video cameras to transmit a signal to a specific, limited set of monitors. Unlike broadcast television, the signal is not openly transmitted but is accessible only to authorized users. CCTV is commonly used for surveillance and security purposes in various settings, such as homes, businesses, public spaces, and government buildings.
Components of a CCTV System
A typical CCTV system comprises several key components:
- Cameras: These are the devices that capture video footage. Cameras come in various types, including analog, digital, fixed, and PTZ (pan-tilt-zoom) cameras.
- Monitors: These display the video feed from the cameras. Modern systems often use computer monitors or mobile devices for this purpose.
- Recording Devices: These include Digital Video Recorders (DVRs) and Network Video Recorders (NVRs) that store footage for later review.
- Cables and Connectors: These transmit the video signal from the cameras to the monitors and recording devices.
- Power Supply: This ensures that all components have the necessary power to operate.
