An electronic device capable of reacting to the impact of photons, converting them to an electrical current that is then passed on to the A-D converter. The most commonly image sensors used in digital imaging are CCD, CMD and CMOS.
Indicates the type of semiconductor which handles video processing inside of a camera. Older CCTV cameras used tubes to process light information. CMOS and CCD image sensors are the most widely available for security cameras in today's market. CCD cameras provide by far the highest quality video of any type of image sensor. Input Voltage indicates the type of electrical current (AC or DC) and the voltage required to safely and effectively power a device.
A traditional camera exposes a piece of light-sensitive film, digital cameras use an electronic image sensor to gather the image data. See "CCD" and "CMOS" as well as "Interlaced" and "Progressive Scan" .
An image sensor is a device that converts visual image to an electric signal. It is used chiefly in digital cameras and other imaging devices. It is usually an array of charge-coupled devices (CCD) or CMOS sensors such as active pixel sensors.
