Q:Buy monitor camera attention to what

Due to the manufacturers in the DSP and related technology between the level of differences, so the product is also different, so the parameters are marked with the gap, and some marked 500 lines, and some standard 520 lines, there are marked 530 lines, the highest marked 540 lines, Even 600 lines. So a variety of line number classification, in fact, shows the differences between the various, of course, which also mixed with a small amount of domestic enterprises to 480 lines fake 500 lines above the product composition. In fact, even in the same 540 line products, because the manufacturers of production technology differences and DSP technology differences, the same line of products with different results. But with the naked eye to distinguish is more difficult to compare out, unless the professional testing equipment or image magnification to distinguish, or find one or two real high-end brand camera to contrast. But in essence, 520 lines or more are called high-definition cameras, but analog cameras in the existing DSP and manufacturing technology based on a limit upgrade, it will be the traditional 480 line HD standard to 520 lines Or 540 lines.

Q:Monitor camera parameters how to see

Aperture: the aperture installed in the back of the lens, the greater the aperture open, the greater the amount of light through the lens, the higher the clarity of the image; the smaller the aperture, the smaller the amount of light through the lens, the image clarity low. Usually with F (luminous flux) to represent. F = focal length (f) / light aperture. In the camera's technical indicators, we can often see 6mm / F1.4 such parameters, which indicates that the focal length of the lens is 6mm, luminous flux of 1.4, then we can easily calculate the aperture of 4.29mm. In the case of the same focal length f, F value is smaller, the greater the aperture, reach the CCD chip, the greater the luminous flux, the better the lens.
