title: ONVIF : How to form the device web service address from the IP address of an NVT
body: <p>My question is about the ONVIF specification.
  <a href="http://www.onvif.org/imwp/download.asp?ContentID=18006" rel="noreferrer">http://www.onvif.org/imwp/download.asp?ContentID=18006</a>
  In section 5.10, it says :</p>
  
  <blockquote>
    <p>A service is a collection of related ports. This specification does not mandate any service naming principles.</p>
  </blockquote>
  
  <p>Lets say that I have the IP address of an NVT (Network Video Transmitter like an IP camera for example), how do I form the address of the device management web service? This service is the entry point of the whole system.</p>
  
  <p>Thank you.</p>
