You may use another camera to capture small details. These cameras have a lot of image quality needs. In general, the TV Lines per inch indicate the image quality produced by the camera. Security cameras for general purpose usually have up to 400 to 420 TVLs. CCD cameras usually deliver better image quality as compared to CMOS cameras.
