I have looked and looked and all i have found are cheap "walkie talkie" apps with huge delay and or are only Bluetooth connect. I have 3 first generation iPADs bought on craigs list, 2 are rather banged up but I have them mounted on the wall so you cant see the damage, and I am using them for Sonos, Nest and Home security but would really like to use them as a HOME INTERCOM SYSTEM as well. They are mounted in LANDSCAPE and I thought of using SKYPE but you cant make the iPad SKYPE auto answer. Any ideas???
