View Restriction Setting Tool
Tip
Even when view restrictions are set, an area outside the view restriction may still appear
momentarily when the camera is controlled near the boundary of the view restriction.
To cancel the view restrictions, clear the [Apply the view restriction] check box and then
click the [Apply] button, followed by the [Save view restriction settings] button.
If the setting fields are cleared while the [Apply the view restriction] check box is selected,
the maximum view restriction will be set.
The controllable range and range that can be captured are as follows.
Maximum left/right captured area
2-20
Pan controllable area
Maximum wide-angle viewing angle
