You can link video to the objects shown on a map. This allows making video surveillance more visual and informative.

The feature is available through immersion mode (see Immersion mode).

To link video to a map, use the four attachment points. Objects in the video need to be linked to their depiction on the site map.

To link objects with symbols on the map:

  1. Click an object in the video. A point is added.

    Important!

    When specifying points on an image, follow the rules:

    1. All 4 points should belong to the same horizontal plane. Place points on the floor or on the ground.

    2. Do not place 3 points on one line.

    3. Points should show the perspective of the plane.

  2. Click on the depiction of the object on the map. A second point is added, connected by a line to the first point.

Important!

When a fourth link is made, it is possible that the second point cannot be placed in some areas. This occurs when the system cannot find a valid angle for displaying the video and map for the given links. Most likely, the links have been set incorrectly.

After a fourth link is added, an angle is chosen so that the surveillance objects in the video and on the map coincide.

To remove a link, place the cursor above the first point in the link and click the  button. After all links are added, it is possible to change the location of previously set points by dragging them while holding the left mouse button.

To save links between video and the map, exit layout editing mode and save changes. The links you make are discarded if any of the following occur before you exit and save changes:

  • The position of the video camera icon on the map is changed.
  • The angle of display of the video display area for the camera on the map is changed.
  • The field of view of the camera on the map is changed in any way.
  • No labels
