The DS-2CD2742FWD-IS 4 MP WDR Dome Network Camera with IR by Nodac Technology in Miami, Florida is a high-performance camera that offers clear and detailed images. It features a 1/3'' Progressive Scan CMOS sensor, WDR, and IR for enhanced image quality.
Automatic Gain Control is a function that automatically adjusts the signal strength for an appropriate level for viewing and recording. In camcorders, the AGC automatically adjusts the sensitivity (in terms of lighting) of the sensor to reproduce a balanced image, depending on the lighting conditions of the installation. It is especially useful in cameras that work with a low level of light. The most common gain values are between x4 and x10 (the higher the gain, the better the camera).
Common Interchange Format (CIF)
The Common Intermediate Format (CIF) is a format that seeks the compatibility of the various digital video formats. A standardized format that is used by any H.261 encoder. Its goal is to offer a reduced common video format for encoders. It is also known as Full CIF or FCIF to differentiate it from Quarter CIF or QCIF.
NTSC and PAL standards
NTSC is the predominant analog video standard in North America (National Television Systems Committee). PAL is the predominant analogue video standard in Europe (Phase Alternation Line). Both standards come from the television industry. NTSC has a resolution of 480 horizontal lines and a refresh rate of 60 interlaced fields per second (or 30 full images per second). PAL has a resolution of 576 horizontal lines and a refresh rate of 50 interlaced fields per second (or 25 full images per second). The total amount of information per second is the same in both standards. When analog video is digitized, the maximum number of pixels that can be created will be based on the number of TV lines available to be digitized. In NTSC, the maximum size of scanned images is 720×480 pixels. In PAL, the size is 720×576 pixels (D1). The most commonly used resolution is 4CIF 704×576 PAL / 704×480 NTSC.
