Monitor the camera 1/3 and 1/4 of the difference there is nothing different CCD what is it
CCD, English full name: Charge-coupled Device, the Chinese full name: charge-coupled components. Can be called CCD image sensor, also known as image controller. A CCD is a semiconductor device that converts an optical image into a digital signal. The tiny photoreceptor implanted on the CCD is called the pixel (Pixel). The higher the number of pixels on a CCD, the higher the picture resolution it provides. The CCD acts like a film, but it converts an optical signal into a charge signal. CCD has a number of neatly arranged photodiode, can sense the light, and the optical signal into electrical signals, the external sampling amplifier and analog conversion circuit into digital image signal.
Monitoring camera is a semiconductor imaging device, with high sensitivity, anti-glare, small distortion, small size, long life, anti-vibration and so on. Surveillance camera security system, the image generation is mainly from the CCD camera, can also be stored out of the charge to change the voltage, with anti-vibration and impact characteristics are widely used.
1/4 and 1/3 refer to the size of the camera's sensor chip. The camera image sensor (CCD or CMOS) has an area of 1/3 inch or 1/4 inch. The same manufacturing process and standards, the larger the image sensor (CCD or CMOS) area, the better the image quality (resolution).
