Is DS-7608NI-E2 / 8P compatible with H264+ ??

Windows PC (windows 10). Interesting that Restlet was installed with 0 requests allowed. It also appears the quotas will be reset to hopefully other than zero later today at 17:00 (though not sure what time zone)

If you're up for it, let's try curl. Download curl for Windows.
Extract the curl.zip file you downloaded to C:\curl
Open a command prompt and navigate to the curl folder.
Create a xml file (I use Visual Studio Code) in the curl folder called ONVIF_on.xml
Contents of ONVIF_on.xml:
<Integrate xmlns="http://www.isapi.org/ver20/XMLSchema" version="2.0">
<ONVIF>
<enable>true</enable>
</ONVIF>
</Integrate>

Amend and run the following from the cmd prompt:
curl -T ONVIF_on.xml http://admin:xxx@192.168.1.xx/ISAPI/System/Network/Integrate
If WEB Authentication is set to digest/basic (Configuration>System>Security) on your NVR you should see the following:

I created the xml file using Notepad++ and after I changed both authentications (RTSP and WEB) to digest/basic from basic, I get what's shown below. Do I need to reboot the NVR after changing the authentications? If so, it will be when I get home in a few hours.

I'm running an unofficial version firmware on my NVR which is giving me more options than than v3.4.98. I'll revert to your firmware and get back to you.
 
Your E series and my K series are similar but the firmware files are radically different in size. You could load the latest firmware for your NVR. Either way, please run the following from a tab in Chrome/FF (if you prefer to keep the responses private msg me):
http://admin:xxx@192.168.1.xxx/ISAPI/System/Network/Integrate
Should return something like:

Finally (may not work or return nothing on your NVR):

Setup: NVR is DS-7608NI-E2 / 8P, FW 3.4.98 build 171121 with 7 cameras. Four of the cameras are in H264+ mode.

While connecting to the NVR remotely (via OpenVPN), I can see playback videos of all the cameras, but I cannot view the main-stream, real-time videos of the four H264+ cameras (I can view their sub-stream though). I believe the main-stream comes out of these camera encoded in H264+. At home, the real-time videos show up as expected on a TV.

Note: when I remotely log directly into any of the H264+ cameras, I see the main-stream video as expected. This is strange because the camera's H264+ stream passes through the NVR (and is decoded there?) before being piped to Internet.

I believe the video playback is a replay of recorded NVR data, though not sure if that is pre- or post-decoding, while the real-time data is decoded in the NVR and then piped through the Internet.

Is my NVR the problem (can't decode H264+) ?

Thanks

This is the same setup as the swan nvr8 7200 , networking these cameras are a bitch, you could try the swannview plus app put in your HID ( if they have one like swann ) number and your on simple, email google needs security removed and 2 step verification to work,
