simple but complex

At its simplest you just launch it on two devices, click "camera" one one and monitor" on the other.
I have yet to get the app to create a steady stream of video without delays, pauses and corruption, but it is effective enough that I use it to re-aim the satellite dish when the horses or weather tweak it off a few degrees.
Point the iPhone at the TV in camera mode and take the iPad outside in monitor mode and I can watch the signal strength while outside adjusting the dish.

Given the drain on the battery I can not see using this as a security or long term thing, only for quick little tasks like this.
