Our Goal at LTM is to guide buyers toward the best possible and most economical type of CCTV equipment available on the market.

All CCTV security cameras produce images using CMOS or CCD chips.

Very low price and usually poor quality CCTV cameras usually use CMOS technology, which produce poor quality images and have very poor light sensitivity.

Decent quality CCTV cameras use CCD technology. The size of the CCD chip is normally 1/4, 1/3 or 1/2. As a rule the larger the size, the higher the quality of the image produced and the higher the price. However, higher density 1/4 or 1/3 CCD chips can now produce as good an image 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 hence, overall picture quality. Standard resolution camera may have 350-380 lines, over 400 TV Lines is generally considered very good resolution while over 450 TV lines are considered the best.

Colour cameras offer more realistic and natural picture (for descriptions of people its better in colour ) even when used at night with built-in infrared light.
