You can calculate the focal length of a zoom camera if you know the optical zoom ratio. To check the optical zoom ratio, choose Settings > System > Visible Area
in the camera web system, click Lens Info, and check the value of Optical zoom ratio. If the focal length of an ITS camera ranges from 11 mm to 40 mm, an
optical zoom ratio of 1x indicates that the focal length is 11 mm, 2x indicates that the focal length is 22 mm, and so on.
