focalLength

Set the fixed focal length with a float value. When this parameter is configured, the other focus methods and parameters will be disbaled and the focal length will be fixed. Users can reset the focalLength to -1 to disable the fixed focus settings. The closer to the 0, the further the focalLength will be.
