Application selection of telephoto security surveillance lens

HD telephoto surveillance lens For different application areas, you need to choose lenses with different focal lengths. The short-focus lens has a wide visual range and is only for large-scale security monitoring. The long-focus lens is suitable for high-end finance, transportation and other fields, pursuing details. Regarding the focal length of the lens, high-definition cameras pursue perfect image quality. In addition to fixed-focus lenses, they should also be connected to an automatic zoom lens, which solves the problems of large-scale monitoring and details. As we all know, the selection of the lens must correspond to the size of the sensor. If the size of the lens does not correspond to the size of the target surface of the surveillance camera sensor, the picture will be out of focus. The general-purpose lens can not only correspond to 1/3-type sensors, but also can be installed and used on cameras with larger 1/2.8-type and 1/2.7-type sensors. The images presented by the same camera under different lenses are quite different, and in severe cases, distortion will occur. Megapixel surveillance cameras must be paired with megapixel lenses. Standard-definition lenses cannot provide perfect 1080p image quality, and cannot achieve the most perfect image quality in terms of horizontal resolution and color reproduction. The above lists the technical requirements of megapixel lenses for high-definition needs. Whether it is a domestic brand or a Japanese lens, it is inseparable from optics, multi-coating, and aspheric technology for HD high-definition lenses. With the continuous development of high-definition surveillance technology, the requirements for the lens are getting higher and higher. How to realize the full HD 1080P image quality without letting the lens drag, I am afraid that security companies will have to work hard on compatibility.
