• The pan and tilt ranges vary depending on the zoom ratio
(view angle).
• If the view restriction will be exceeded as a result of controlling
the zoom toward the wide-angle side, the camera will first pan
and tilt to a position where the maximum wide-angle zoom will
be within the viewing restriction area. Wide-angle zoom control
will then be enabled within the view restriction area.
• Reducing the view restriction may also reduce the zoom range.

Setting view restrictions
automatically restricts
the camera operating
angle. When wide-angle is selected,
the capture of the camera
operating angle would exceed
the view restrictions if it
remained the same. Therefore, it
is narrowed automatically.
