IP 摄像头在端口 1024 上工作，但在 ONVIF 的端口 1025 上工作

Question

I have a problem with my IP Camera. I can enter the camera feed successfully on port 1024 which I have configured in the IP Camera and the router on this address in Chrome:
http://192.168.1.4:1024/web/admin.html

Now there is an ONVIF setting for the IP Camera which I have set like this on port 1025:

I have also on the router done port forwarding for both port 1024 and 1025 like this:

Now when I enter the below URL in the Chrome Browser, I get the below error:
http://192.168.1.4:1025/web/admin.html
<faultcode>SOAP-ENV:Client</faultcode> <faultstring>HTTP GET method not implemented</faultstring>

I wonder what this means and why no stream is coming for the above URL on port 1025?

Answer 1

I see two issues here:

1. Accessing the ONVIF interface through a browser
2. Streaming and NAT traversal

For the first problem, ONVIF works with soap, and therefore it expects to have POST requests. Your browser thinks that it is connecting to a web page and sends a HTTP GET request that makes no sense for soap-based protocols, such as ONVIF.

The second problem is that your router is doing NAT, and moving RTSP streams through NAT is painful. You will find a lot of literature for VOIP, that uses RTSP and here the problem is exactly the same. You have two possible solutions:

1. Using HTTP as transport for your video instead of any other transport. This is the only NAT-friendly transport in ONVIF
2. Using a router that supports full cone NAT, configuring several rules in the router ahve making sure that the camera uses always the same ports for streaming.
