title: WS-Discovery for cameras on different logical network
body: <p>I have a unit running python that needs to use ws-discovery to locate onvif cameras that may be on different logical networks. Does anyone know if this is possible?</p>
  
  <p>(I got discovery on same logical networks working using this library: <a href="https://github.com/hlamer/python-ws-discovery/blob/master/WSDiscovery.py" rel="nofollow">https://github.com/hlamer/python-ws-discovery/blob/master/WSDiscovery.py</a>)</p>
  
  <p>After a bit of searching, I came across  'remote discovery proxies' which sounds promising, but I cant figure out what they are exactly.</p>
