How Privacy Zones are Programmed
Privacy Zones are established by selecting three points on the display image to create a mask.
The fourth point on the Privacy Zone is automatically generated by mirroring the longest axis
between the three selected points. Figure 4-2 illustrates how Privacy Zones are programmed.
Figure 4-2: Privacy Zone programming example
The dome's firmware prevents you from establishing a zone that is too small or too large
(greater than 90-degrees pan or tilt from the starting point).
Figure 4-3 illustrates the Privacy Zone programming screen:
Figure 4-3: Privacy Zone Programming screen
The circled arrows represent the target area on the screen for creating the Privacy Zone.
Normally, this target area remains in the center of the screen. Using the Pan/Tilt control
moves the target area by panning or tilting the dome. If the dome reaches its maximum tilt
position, the Privacy Zone may still be established in the upper part of the display. When this
occurs, the arrows move relative to the movement of the Pan/Tilt control until the top of the
display area is reached.
