title: Sony Alpha 77M2 Remote control over USB
body: <p>I have three Sony Alpha 77M2 cameras, and I'm trying to take photos with all three simultaneously, and retrieve these photos. I can do the simultaneous shutter release using commercial remote triggers synced off a single transmitter, and I can control a single camera over USB using the Sony Remote Camera Control software - however this can't control more than one camera, and it won't let me run more than one instance on a single machine.</p>
  
  <p>My question, therefore, is whether there is an API available for the USB remote control interface for these cameras? They don't support the WiFi API, so I can't use that (and WiFi isn't much use for the environment this system will be used in, due to the likelyhood of interference)</p>
