When the human eye can not stretch the lens to the normal position, that is, people often say myopia, the front of the scene becomes blurred; camera and lens with a similar phenomenon, when the image becomes unclear , You can adjust the camera's back focus, change the CCD chip and the lens reference plane distance (equivalent to adjust the position of the human eye lens), you can blur the image becomes clear. Thus, the role of the lens in the closed-circuit monitoring system is very important. Engineering designers and construction workers should often deal with the lens: the designer according to object distance, imaging size calculation lens focal length, the construction staff often on-site commissioning, part of the lens is to adjust to the best condition.

2, the lens sub-focus lens and zoom lens. Zoom lens focal length is variable, the scene can be closer to or push away, to achieve several times the zoom effect, use it to the blackboard on the board book clearly, can also be the whole picture of the classroom, the focus can not be achieved this function. Equipped with a lens for the electric three variable lens, can be zoom, focus and aperture adjustment.
