*Area initially displayed using the Area Mask ON
command.
Notes:
Up to 8 mask can be displayed within one view angle.
When module is mounted on Pan Tilt Dome Camera,
PAN/TILT Angle info must be sent to the module
camera in advance.
To hide the masked subject more precisely, update
the PAN/TILT angle info within the interval of less than
75 msec.

after calculating out the coordinates at the
Wide-End against the current zoom ratio.
