*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:

pMask Number (No. 1-15)

qrs Pan Angle (0°-360°)

xTilt 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.

Area Mask Position Set

Command: A0 10 09 0p 0q 0r 0s 0t 0u 0v 0w 0x CS

FF

Parameter:

pMask Number (No. 1-15)

qr	x-Coordinate Start Position
st	y-Coordinate Start Position
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.

*Query Command Mask Position responds in the 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˚
	PAN = 90˚
PAN = 0˚ / 360˚	PAN = 180˚
TILT = 0˚	TILT = +/−180˚
	PAN = 270˚
	TILT = 90˚
