Relay objects can be relocated in the object tree. To change the parent  parent Video Capture Device object of the Relay objects, change the value of the Video Capture Device object on the settings panel of the Relay object. The value of this parameter is to correspond to the number of the Video Capture Device object (in the object tree) under which the Relay object is to be located. If the value of the Video Capture Device parameter is changed on the settings panel of the Relay object, then the object is moved to the branch of child objects of the corresponding Video Capture Device object.
