Once you download this app to an old iPhone or iPod Touch (and soon, Android devices), setting up a video stream over either Wi-Fi or 4G takes less than a minute. The company will even mail you a window suction cup mount to give your old device the best possible view.
You can use any old iPhone to create a live stream of anything--your kids playing in the basement, your spouse working out in the living, or the line at the move theatre across from your office. And if you share your live stream, then you are entitled to view any of the other live streams shared on Koozoo's network.
According to the Verge, the phone takes a snapshot every few minutes to use as a thumbnail, and only broadcasts live when a viewer using the Koozoo app tunes in.
