I am a Realtor in Southern Indiana. I am wondering how much an entire home system integration would cost. I am not well versed on many of the different systems however I would very much like to learn about the different capabilities of systems out there and the price range they are in. I would like to be able to control tv’s (and put my movies onto an entire house hard drive to be able to be played on any tv in the house), lights, furnace-a/c, front door lock/monitor, security cameras, etc. and be able to control it all from my HTC EVO or some other remote. I just am not sure exactly what is capable and possible right now. Also with what price tag does it come with for an average 2,000 sq/ft home?
