z The pan and tilt ranges vary depending on the zoom ratio (view angle).

z 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.

z Reducing the view restriction may also reduce the zoom range. 

When the view restriction is 
set, the camera operation 
angle is automatically 
restricted.

Camera

When a wide-angle is used 
without changing the camera 
operation angle, the view 
restriction is violated, and 
therefore the operation angle 
is automatically narrowed.

Captured image

First, the center of the 
maximum wide-angle 
zoom is panned and tilted.

After panning and tilting, 
wide-angle zoom control is 
enabled within the view restriction.
