Ok, but I have another solution. If you have access to a computer in the remote location do this.
-install a version of NCS on the local machine and add it using the onvif tab. and find the url in the tab for custom url.
-alternative is to download ONVIF DEVICE MANAGER.
-install and run and ODM detects the camera if it supports onvif.
-here you find the url to use
