Click the Image to Set Camera Angle
Click the desired position in the image and the camera
angle will move to center that position on the screen.
However, if the position clicked is beyond the range of the
pan or tilt, the camera angle will move only in the pan or
tilt direction that is within the valid range of movement.
Note
If the camera moves in a different way from operation control or
cannot be set to the range indicated by operation assist, then
operation assist may not correspond to the actual camera angle.
Click [Control Assist Correction], then try to set the camera angle
again.
