I noticed this problem earlier today and have been doing some troubleshooting.
The symbol in the bottom left of streams indicates streaming via the cloud even when on the same LAN:
I have put my laptop on the same subnet as the camera and still see the Cloud symbol.
I've done a packet trace on the switchport the camera is on with a filter expression of "host n.n.n.n", with n.n.n.n being my laptop address and no data is captured, so its deffo going via the cloud.
If I look in the Video Access menu that also says I viewed via cloud access.
Looks like something has gone wrong here as its at every site.
