Why does my Zee S2 Pi constantly display "streaming bytes"?

[Otto-mation]

Out of curiosity, I plugged my Zee S2 into a monitor and see the following appears almost all the time now.
I don't have any cameras configured.
The only plugins I have are AK-weather related - once per hour.
Is this "streaming" thing normal or should I be trying to debug it?

Thanks and Happy (Cdn) THanksgiving!
