Missing exposure control, but works fine for me.

While I wish the app had a control for exposure instead of brightness, this makes my new CS920 serviceable. I’m running El Capitan. Zoom works, pan works. I’m not sure what the prior version did differently, and I’ve heard rumors that the Windows version sllows face tracking, but overall this makes the camera workable. I was going to return the camera to Amazon, but this way I’m pretty content.
