Older 4 Story Building dense urban setting in Brooklyn NY.
Main Components to be housed on second floor.
Communication desired between 1, 2 and 4th floors, skipping 3rd.
Older wiring that is all over the place makes me nervous about Insteon over the wire, but the dense radio noise from a couple dozen wifi bases picked up and the two cab companies nearby are the other end.
Finishing up the audio/video stuff, which is all IR and IP. Moving on to the lighting.
Suggestions from experience appreciated...
