Programming Area Boundaries
If the dome is installed in a location where you can see numerous departments or other
identifiable objects, you might want to consider programming area boundaries.
Areas are
programmed start- and end-points of a camera's field of view. Each area is a part of a circular
viewing area that extends around the dome.
For example, Figure 4-1 represents the floor plan of a break room. The room includes a main
entrance, tables with chairs, vending machines, lockers, and an emergency exit. Areas have
been programmed around the fixtures in the room. As shown in this example, areas can be
different sizes.

The ending point of one area is the starting point for the next area. The ending point of the
last area cannot go past the starting point of the first area. In this example, the area that
includes the vending machines cannot extend past the starting point of the area that includes
the emergency exit. If your controller supports areas, these are separate from the areas you
can program with the dome. You should not use both the controller and the configuration
utility to define areas.
The zoom level also affects how large areas appear. When you zoom in to an area, the area
may appear to be small. When you pan the dome, area boundaries may appear to be close.
However, if you zoom out, the area appears to be larger. When you pan the dome, the area
boundaries appear further apart. With this in mind, it will be easier to establish area
boundaries if the zoom level is small than if the zoom level is large.
