This tutorial will walk you through setting up an ATEM Mini Pro kit you can ship to a remote location and then control from your studio. You can use this to ship a remote interview kit to someone where all they have to do is plug in a few connections and you'll be able to control everything remotely!
Thinking about creating a "private network" -- a network only visible when you are physically close enough to me to pick up the wifi hotspot I'm broadcasting. Could be used to send messages to me or share photos with small groups. Would also be great in low-connectivity areas!
