    Magnifying Part of the Image (Viewer 
    PTZ)
    You can use the Viewer PTZ panel to magnify part of the 
    camera’s image in the image display area. 
    „Viewer PTZ
    Viewer PTZ uses the digital zoom function to enlarge part 
    of a video without using the camera pan, tilt or zoom 
    functions.
    This function allows you to enlarge part of a video when 
    using the camera in a locked position, for example, during 
    use of an intelligent function.
    Note
     Video cropped with Viewer PTZ will not be videos recorded 
    manually, or by event or timer. The cropped position in the image display area will be 
    reflected in full screen mode as well.

    levels from [1] (Mild) to [7] (Strong).
    Example: If the background is bright and the subject 
    is hard to see, this function brightens dark areas to 
    make the subject clearer. 
    In comparison to backlight compensation, smart 
    shade control can reduce overexposure of bright 
    areas. 
    Note
     When [On] is selected for smart shade control, the image file 
    size increases. 
     When [On] is selected for smart shade control, screen noise 
    may increase. If noise is noticeable, lower the control level.

    Important
     If it is set in the Admin Viewer, the same focus mode will 
    occur in the viewers of other users also. 
     Depending on the lighting used, focus may not be 
    maintained when switching between [Day Mode] and [Night 
    Mode]. Focus when switching Day/Night Mode can be set in 
    the [Day/Night Mode Focus Settings] panel in the Admin 
    Viewer (p. 141).
     Setting the shutter speed at [1/1 sec] in manual exposure 
    (p. 140) will disable the [Auto] and [One-shot AF] focus 
    modes in Control for Admin. Switch the focus to [Manual] and 
    adjust it to your subject. 
     Refer to the following for focus ranges.

       Notes on p. 38
     Changes to focus mode in the Admin Viewer will not be 
    reflected in the settings on the setting page. 
     Note that if you set the focus manually it will remain fixed.
