CMOS OR CCD? What is the difference between CMOS and CCD?
As you know security cameras produce images using CMOS or CCD (Charge Couple Device) chips. Tiny, very low price cameras usually use CMOS technology, produce poor quality imagesand which have very poor light sensitivity . On the contrary, good quality cameras usually use CCD technology. The size of the CCD chip is normally 1/4", 1/3" or 1/2". As a rule of thumb, the larger the size, the higher quality of the image produced, of course, the price is much higher. However, higher density 1/4" and 1/3" CCD chips also can now produce an images as good as many 1/3" or 1/2" chips.
The number of TV lines in the security camera image is a measure of picture resolution (sharpness). The larger the number of TV lines, the better the resolution and therefore, overall picture quality is better. Standard resolution camera may have 350-380 lines, if over 400 TV Lines is generally considered good resolution while over 500 TV lines is considered high resolution. B/W chip cameras produce greater resolution and better light sensitivity, therefore cameras with B/W are suitable for shooting in dark areas where light conditions are poor most of the time.
