Currently, Camio uses only the single default camera specified by your browser settings as described in http://help.camio.com/hc/en-us/articles/203795145.
If your computer has more than one camera connected to it, then you can record from each of them at the same time with this workaround:
- open a new window (not tab) for each camera using both Chrome and Firefox browsers at the same time https://www.camio.com/cam.
- select the preferred camera in each of the open browser windows and press the Record button.
- ensure that each camera is the active tab in its own browser window.
