As far as the “Music Tracking” this is a nice feature I currently have in my home. It’s pretty cool and easy to do. Now it doesn’t know who’s in the room but it knows someone is there I go to the pool and, yes, there is music there also! As far as a system that knows whose there, that’s asking a lot for ANY system. Transmitters would be the most logical way to perform this task. I know in the auto security, there is “transmitters” that the car senses and allow a start. Without the transmitter being around, the car won’t start (Corvettes have this). This inexpensive technology could be employed in a home and track people. Also, they are starting to “chip” animals, putting a small microchip just under the skin. This allows identifying of animals at zoos, but it could be used in “your” home. Contact your local vet to see if he would “chip” your family. You could have exterior chips, to be worn as a charm or something, that you could pass out to friends and family who visit.
