After suffering a lot of disconnections with the ONVIF camera I have now connected the camera using a LAN cable. I suspect outside the house the WiFi signal is not that strong. The connection is now 100% and had no dropouts.

I have found an app to help with the ONVIF setup "ONVIF Device Manager" but it does not seem to work as it should.

I am using Windows 10

Tried many menu items which mostly fail....This one "Time settings" fails.
