"GetProfiles" does not work with my ONVIF camera - python-3.x

Question

My task is to control the Cisco ptz camera. However, I can’t even get a token. I successfully connect to the camera, but I get an error when I execute GetProfiles (). Through ONVIF Device Manager, everything works fine and I can see tokens and other information about my camera

I really appreciate any help you can provide.

Answer 1

Are you sure that you are pointing to the correct entry for the device_service? In some infrequent cases, it may be that the ONVIF interface runs on a port different from 80, where the webinterface is running.
In this case, usually a camera responds to the Probe messages by listing the XAddr for the device service with a port different form 80.
I suggest you to use wireshark and to sniff the traffic between ONVIF Device Manager and the camera and to check the correct URI used by ONVIF Device Manager to post the requests.
