`getResolutionList`	Get all available resolutions

Focus & zoom methods

Method	Description
`setAutoFocusPosition`	Set auto focus position (Change the default auto focus position).
`setManualFocusPosition`	Set manual focus position (This focus position is only effected once for each time the API is called).
`setFocalLength`	Set focal length between 0 to 10 to enable fixed focal length mode. In fixed focal length mode, all focus parameters can’t be changed until this mode is quit. To quit fixed focal length mode, please set focal length equals to -1.
`enableDCEAutoFocus`	Set true/false to turn on/off DCE auto focus.
