For cameras that share their field‑of‑view information, you can create a more realistic
effect in the Maps task or Monitoring task in Operation desktop by drawing walls and other
obstacles on your map to block their fields of view.
What you should know
Only lines, rectangles, and polygons, can be used to block the field of view (FOV) of
cameras. Text, images, and elliptical shapes cannot be used for blocking.
Procedure
-
From the Configuration desktop homepage, open the Map designer
task.
-
Select a recent map or click Browse all maps to open an existing
map.
The selected map fills the Map designer
workspace.
-
In the toolbar, click one of the following tools to insert a graphical object:
Draw
line
- Click and drag to draw a single-line segment to represent a wall.
Draw
rectangle
- Click and drag to draw a rectangle. Drag a handle to change its size. You
cannot change a rectangle into a different type of polygon.
Draw
polygon
- Click once for each endpoint, and click the first endpoint to close the
polygon. Use Shift+click to add or remove a point between two points.
Double-click a point to complete the polygon without closing it.
The widgets for configuring the map object appear in the right panel. The map
object always takes on the identity of the entity it represents.
-
From the Physical widget, select Block field of
view and set the Elevation of the wall. Using this
elevation in conjunction with the elevation that is configured in the camera's
Field of view widget provide a visual representation on the map
of the blind spot created by the wall.
-
Test the blind spot created by the object by selecting the camera and clicking
Start test field of view in the camera widget.
