I’m not really sure where this video comes from, couldn’t find a source. I’m not sure this is actually a functioning system.
It appears there is a train that goes under the house, and then the kid pops up into the living room.
This seems a bit over protective to me, unless your kid is the son of the President of the Universe.
Interesting video, though.
