Little, low value CCTV cameras as a rule use CMOS innovation, produce low quality pictures and have poor light affectability. Conventional quality CCTV cameras use CCD innovation. The measure of the CCD chip is ordinarily 1/4″, 1/3″ or 1/2″. As a standard guideline, the bigger the size, the higher the nature of the picture created and the higher the cost. In any case, higher thickness 1/4″ and 1/3″ CCD chips would now be able to deliver as great a picture the same number of 1/3″ or 1/2″ chips.
The quantity of TV lines in the surveillance camera picture is a proportion of picture goals (sharpness). The bigger the quantity of TV lines, the better the goals and consequently, generally speaking picture quality. Standard goals camera may have 350-380 lines, more than 400 TV Lines is for the most part thought to be great goals while more than 500 TV lines is viewed as high goals.
