that it is possible to interact with Foscam camera via that binding in version for openHAB 3.
I know that @mstormi was using it. So id you are using OH3 version of that binding maybe you can share the code of the thing configuration. It would help me a lot.
You can move ONVIF cameras with the ipcamera binding which also has a lot of the foscam api included. OpenHAB 3.1M2 got a fix that helped foscam to get auto detected correctly so update to this as a minimum.
