ONVIF GetStreamUri返回内部IP地址

Question

I am trying to connect to an IP camera using Onvif. This camera is not in my network and has been made available to me through an external IP address. When using the 'GetStreamUri' function I get a RTSP link with the internal IP address of the camera, this will not work. When I replace the IP manually it works just fine.

Does anybody have any other suggestions on how to handle this? Replacing the IP manually works but is not a very nice solution.

A camera behind NAT and with RTSP streaming in general cannot be viewed from Internet, because you'll end up with all the classic problems related to NAT and VOIP (voip uses RTSP as well as ONVIF).

But you have a possible solution: configure the camera so that it streams over HTTP. At this point you should get a URI that should be accessible from Internet. In fact, if you invoke GetStreamUri , the camera will still return you an internal IP address, since it does not know that the router is configured for NAT. If you are lucky enough, the URI will be on port 80, thus by replacing the internal IP address with the external IP address of the gateway you should be able get the video.
