subjectx Thanks for the logs, it looks like orchid is failing to parse an onvif response correctly. Unfortunately you will not be able to register your onvif camera through Orchid. We do not have the camera model you are using to test with.
If you would like to help us determine what exactly is causing the error, you could capture the http traffic between orchid and the camera, so we can see exactly what is in the response that is screwing up orchid.
sudo tcpdump -i any -s 0 'host <camera ip> and port 80' -w /tmp/register_camera.pcap
where <camera ip> is the ip address of one of the cameras.
Then try to add the camera.
Wait until camera fails to add and stop tcpdump (Ctrl-C is fine)
Then share the file with us somehow. Unfortunately it is in a binary format so I'm not sure you can use pastebin. You can try https://wetransfer.com/ or a send a dropbox link. (We are working to get file uploads supported on this site but we don not have that capability at this time)
