Security surveillance camera determines the effect parameters
Security surveillance camera determines the effect parameters, surveillance cameras usually have two of the more important parameters. One aperture, the mounting device which is a little light through the lens to reach the sensor in the camera control, in addition to controlling the amount of light, the aperture further having a control function of depth, i.e., the larger the aperture, the smaller the depth of field. Another is the focal length, it is basically a clear image on the sensor plane distance formed between the center from the lens to. Lens focal length of the lens determines the size of the object captured in the image formed on the sensor. Assuming the same distance from the face of the same object shooting, then the longer the focal length of the lens, the image formed by the object will be.
