Area initially displayed using the Area Mask ON
command.
Notes:
・
Minimum unit for the mask width is 4 pixels
horizontally and minimum unit for the mask height is
2 lines vertically.
・
Up to 4 mask can be displayed within one view
angle.
・
To correctly hide the masked subject when loading
the dome camera, update the PAN/TILT angle
interval to within 75 ms.
Area Mask Degree Set
Command: A0 10 11 0p 0q 0r 0s xt 0u 0v CS FF
Parameter:
p Mask Number (No. 1-15)
qrs Pan Angle (0°-360°)
x Tilt angle sign bit
tuv Tilt Angle (0°-180°)
Usage: Sets the angle of the specified mask numbers.
Note: Set using a pan angle range of 0°-360° and
a tilt angle range of –180°-180°. (Refer to the
diagram on the right)
In addition, when setting a negative tilt angle
set the tilt angle code bit x to 1.

uv x-Coordinate End Position
wx y-Coordinate End Position
Usage: Sets the position of the specified mask numbers.
Note: Set the mask size to sufficiently cover the mask
object. In addition, ensure that the settings are
set on the WIDE end.

same parameter as described above.
Details of the Mask Angle and Position
Setting the Mask Angle (Area Mask Degree Set)
The angle is displayed as 12 bits and divided into 4-bit
units when increased by a magnification of 10.
Example) Setting the mask angle according to the
following parameters during NTSC
Mask Number 1
Pan Angle 135°
Tilt Angle 45°
Pan Angle:
1350
→
0x0546
→
q = 5, r = 4, s = 6
Tilt angle sign bit:
If the tilt angle is positive
→
x = 0
Tilt Angle:
450
→
0x01C2
→
t = 1, u = C, v = 2
Transmitted according to the following.
A0 10 11 01 05 04 06 01 0C 02 CS FF
According to the setting above, if the tilt angle only is
set to -45 degrees the following codes are transmitted.
A0 10 11 01 05 04 06 11 0C 02 CS FF
TILT = −90˚
TILT = 90˚
PAN = 90˚
PAN = 270˚
PAN = 180˚
TILT = +/−180˚
PAN = 0˚ / 360˚
TILT = 0˚
