What is a CCD Sensor?
Most CCTV cameras are now almost exclusively ‘CCD’ sensor type. CCD stands for Charge-Coupled Devices. These are light-sensitive chips, the sensitive area being split into a large number of individual pixels (Small dots on the chip). An image from a scene is focused through a lens onto the chip surface and charge is built up in each pixel proportional to the intensity of the light falling on it. Hence an electrical representation of the optical image is formed. Typical active pixel counts for CCD sensors are between 250,000 and 500,000 pixels. Cameras are available in both monochrome and color types. Lenses Note that WECU Surveillance Security Cameras, supply cameras without filled. This is because there are many different types of cameras and even more types of lenses and so it would be impractical, and very expensive, to stock all possible permutations and combinations to meet each application. So Please REMEMBER to include the LENS! The field of view (FOV) How much will the security
