If you wish to create the following view in your Echo360 recordings in SC360, you must consider the following:
On the Echo there are two video inputs. Primary and secondary. The primary input is always the middle screen. The secondary input is the screen on the left from the teachers point of view. (Facing the students screen is on your left).
So if you have the pc showing on all three screens it will be recorded twice. If you have the pc on the middle and a laptop on the sides like Jim, it will record the pc as primary and the laptop as secondary.
Now, there is a button in the bottom right of the touch panel labeled "Echo Camera." What this does is overwrite the secondary input and sends it the camera feed. That way you can send the echo the camera without displaying the camera on the left screen.
