Blocking camera fields of view on maps

2026-08-27Last updated

To create realistic camera coverage simulations in the Maps task or Monitoring task in Genetec™ Operation, you can configure map objects to block camera fields of view and display blind spots caused by walls and other obstacles.

What you should know

Only lines, rectangles, and polygons can block camera fields of view. Text, images, and ellipses cannot be used as blocking objects.

Procedure

  1. In Genetec™ Configuration, open the Map designer task.
  2. Select a recent map or click Browse all maps to open an existing map.
  3. 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.
  4. From the Physical widget, select Block field of view and set the Elevation of the wall. The wall elevation, together with the elevation configured in the camera's Field of view widget, determines the blind spot shown on the map.
  5. Test the blind spot created by the object by selecting the camera and clicking Start test field of view in the camera widget.
    The following example shows how the field-of-view test results change based on the wall configuration.
    Example Configuration
    A Block field of view is not selected for the rectangle representing the parking garage.
    B Block field of view is selected for the rectangle representing the parking garage.
    C Block field of view is selected for the rectangle representing the parking garage and the Elevation is defined for both the parking garage and the camera.
    Tip:
    To test the coverage of all the cameras, click Map > Show field of view coverage .
  6. In the Map designer toolbar, click Save ().
