I wonder if there is a virtual fence application for the Alpha 200 I F + KT15x dog collar set? I want to define a few GPS points on the map and the dog to be electrically warned by the Alpha 200 I F + KT15x collar set when it intends to leave the perimeter defined by the points mentioned above. If the application exists, please tell me what it is called? And where do I find it to install it? If the application does not exist, please recommend me an experienced person willing to develop such an application.
