A:AnswerIf you are connecting your phone as a remote then yes it does require wifi I'm not sure if the connection type is Bluetooth or private wifi for the included remote. I can tell you that the included remote works much better than the wifi connection to a phone. The phone keeps dropping out even when you are standing right next to it.
