Anyone know of an app besides Facetime that could transmit a live feed from an iphone to another iphone, or to a mac? I'm trying to setup one phone to be maneuvered around a tight location and transmit the video (either by lightning cable, or wirelessly) to another Apple device to see what the phone's camera sees. I just tried this one freebie bluetooth app on the app store (Remote Live Camera) which did not work at all, just froze and did nothing. Hoping for a recommendation that's been tried. Thanks !
