PRAMA Prama 8CH Eco Dvr Security Camera  (6 TB, 8 Channel)

A CCTV camera, also known as a closed-circuit television camera, is a type of surveillance camera that is used for monitoring and recording activities in specific areas or premises. It is typically connected to a viewing or recording device, such as a monitor or digital video recorder (DVR). CCTV cameras come in various shapes, sizes, and designs, depending on their intended use and location. They can be small and inconspicuous, resembling a dome or bullet shape, or larger and more visible for deterrent purposes. Some cameras are designed for indoor use, while others are weatherproof and suitable for outdoor installation. Key features of a CCTV camera include: 1. Image Sensor: The image sensor captures visual information and converts it into an electronic signal. 2. Resolution: The resolution refers to the level of detail and clarity in the captured images. Higher resolutions provide sharper and clearer footage. 3. Lens: The camera lens focuses the incoming light onto the image sensor. Different lens types, such as fixed or varifocal lenses, offer varying degrees of zoom and focus capabilities. 4. Infrared LEDs: Many CCTV cameras are equipped with infrared LEDs to provide visibility in low-light or no-light conditions. These LEDs emit infrared light, which is not typically visible to the human eye, but can be detected by the camera. 5. Field of View: The field of view (FOV) determines the extent of the area that the camera can cover. Wide-angle lenses offer a broader FOV, while narrow-angle lenses provide a more focused view. 6. Pan-Tilt-Zoom (PTZ): Some advanced CCTV cameras have PTZ capabilities, allowing remote control of the camera's movement, including panning, tilting, and zooming. 7. Connectivity: CCTV cameras can be connected via wired or wireless networks, enabling live monitoring from remote locations and facilitating recording and storage of the surveillance footage. 8. Video Compression: To optimize storage space and transmission bandwidth, CCTV cameras use video compression algorithms to reduce the file size of the recorded footage while maintaining acceptable image quality. Overall, CCTV cameras serve as a surveillance tool for security, crime prevention, and monitoring purposes in various settings such as homes, businesses, public areas, and transportation systems.
