Sometimes certain zones within the camera view should not be monitored for privacy
protection. For example, if the view shows the windows of an apartment building in the
monitored zone, choose to not record the apartment. The zone options are: ON or OFF.
When ON, you can manually set up privacy zones. Click the >> button to view a full
image of the camera feed. Left-click and drag to select zones to be grayed out on the live
feed. Select as many multiple isolated and/or overlapping zones as needed. Right-click on
the window to return to the Video menu. The changes take effect when you save and exit
the menu.
