Cameras using CMOS technology usually have poor light sensitivity and produces poor quality images. The larger the chip the better images it may produce but you should expect that it is more expensive. The picture resolution of the security camera image can be measured by the number of TV lines. The larger the number of lines, the better resolution and picture quality you can expect.
