title: Delphi Onvif SOAP Calls
body: <p>I'd like to get started using Delphi to access and control IP-cameras with the Onvif SOAP protocol.</p>
  
  <p>However, I do not understand how to actually perform the calls from Delphi.
  I've imported the following WDSL:</p>
  
  <p><a href="http://www.onvif.org/ver20/ptz/wsdl/ptz.wsdl" rel="nofollow">http://www.onvif.org/ver20/ptz/wsdl/ptz.wsdl</a></p>
  
  <p>and a unit was generated in Delphi. But how do I perform the calls towards the camera? Am I supposed to use this generated together with THTTPRIO somehow? How to I specify the IP-address of the camera I have (currently an Axis Q1755 camera).</p>
  
  <p>If someone could get me started by pointing me in the correct direction I would be very grateful.</p>
