From couple of years Hikvision doesn't provide new IP cameras with defaults password for some strange security reasons and new user is forced to set unique password via web interface. In my case I need to activate hundreds of cameras and it will take too much time to do it via web.
I tried to make it via ONVIF SetUSers (http://www.onvif.org/ver10/device/wsdl/SetUser), but recieved:
ONVIFError: Unknown error: (401, u'Unauthorized')
Also i tried ISAPI protocol with /ISAPI/Security/users, but also no luck without any response at all. Of course, after activation ONVIF and ISAPI work fine. Is it any alternative way to automate activation process?
