Turn wifi equipped iPhones, iPods, and iPads into a wireless tally system for your NewTek Pro series or Mini TriCaster.
You simply tell the app the ip address of the TriCaster, which input you want to monitor and it will display black, Green (Preview) or Red (Program) based on the TriCaster switching. No software to be installed on the TriCaster!
Whether for mounting by a camera or for putting right in front of your talent this app can provide you with a very flexible tally system.
