When automatic fusion is enabled, the RSA plugin identifies two targets that represent the same intruder and merges the targets into one. A merge occurs when two targets are within a specified distance from each other. This distance is configurable.

What you should know

By default, auto fusion is disabled. When auto fusion is enabled, you can change how far or close together the targets are when they are merged, so that you avoid false merges.
A single target might be detected as multiple separate targets in the following cases:
A tracking device loses the target for a period of time, then detects the target
If a target is hidden from the tracking device for an extended time, perhaps by going behind a building, when the target reappears, the tracking system might detect it as a new target.
Multiple detection devices detect the same target
If you have different types of tracking systems in the same zone, such as radar, laser, and thermal detectors, each device might detect the same target.


  1. From the Config Tool home page, open the Plugins task.
  2. Select the Restricted Security Area Surveillance role, and then click the Properties tab.
  3. In the Auto fusion section, set State to ON.
  4. In the Sensitivity list, choose on of the following settings.

    Merge two targets that are less than 1 metre (3.3 feet) apart.
