support privacy mask function. If there is certain
location within the surveillance area where operators are not
allowed to see, and thus, PRIVACY MASK can be applied. System
covers and shields the sensitive area via Privacy MASK setting, to
avoid operators observing certain sensitive locations on monitor.
Area: Two coordinates determine an area. The line between those
two points is the diagonal of detection area. Each point extends
along 2 lines perpendicular to the X Axis and Y Axis, and the
rectangle formed by those 4 crossed lines is the motion detection
area. The selectable value on X Axis can be any of whole numbers
from 0 to 44, while Y Axis can be any of whole numbers from 0 to
36.
Note: The horizontal ordinate and vertical ordinate of the second
point should be greater than that of the first point. Plus, the area of
Privacy Mask shouldn’t over 396. User can use formula:
(X2-X1)*(Y2-Y1) to calculate the area. Tick “Enable” means
Privacy mask function is enabled. After finishing the setting, click
“Set” to make it effect.
