Hilvision IP cameras, unable to GetNetworkInterfaces()

[tetherit]

Anyone else experienced this with Hikvision cameras?

>>> mycam = ONVIFCamera('192.168.88.14', 80, 'admin', 'password2', '/usr/local/wsdl')
>>> mycam.devicemgmt.GetNetworkInterfaces()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/site-packages/onvif/client.py", line 32, in wrapped
    raise ONVIFError(err)
onvif.exceptions.ONVIFError: Unknown error: (400, u'Bad Request')

I'm able to do other things such as GetCapabilities:
