Different focus lenses should be selected for different application fields. Short focus lenses have a wide viewing range, only for large-scale security monitoring. Long focus lenses are suitable for high/end finance, transportation and other fields, and pursue details. About lens focus, HD video camera In pursuit of perfect/beautiful picture quality, in addition to the fixed focus lens, it should also be able to access the automatic zoom lens, which solves the problem of large-scale monitoring and details.

In addition to corresponding to 1/3 type sensors, the universal lens can also be installed and used on the cameras with larger size of 1/2.8 type and 1/2.7 type sensors.

The images of the same camera under different lenses are very different, and in serious cases, distortion will occur. The megapixel surveillance camera needs to be equipped with a megapixel lens. The standard definition lens cannot provide perfect/beautiful 1080p image quality, and cannot achieve perfect/beautiful image quality in terms of horizontal clarity and color reproduction.

Whether it is domestic brand or Japanese/Japanese lens, HD lens can not be separated from optical, multi coating and aspheric technology. With the continuous development of high-definition monitoring technology, the requirements for the camera are also getting higher and higher. Security enterprises may have to work hard on compatibility to achieve full high-definition 1080P image quality without letting the camera lag behind.
