Firstly, you can resolve this by using iVMS, manually adding in your NVR using the locations public IP or a
DDNS followed by port 8000 and the user credentials.
But. Even though that solves the overall issue, It still doesn’t answer your questions so here’s a list of potential reasons.
assuming you’re using a Mac, this is a known issue. And one im also pulling my hair out over as well. There is kind of a web page fix though. You’ll need to roll back your firmware. I found that to somewhat resolve the problem for me.
make sure your cameras bandwidth and frame rates are not crazy high on Main and Sub streams
https traffic is encrypted. Hikvision has been kind of wonky about their certificates and browsers don’t see their self signed Cert as trustworthy I guess... that’s less likely the issue
make sure you allow your browser custom permissions for that page. The browser could be blocking the feed
could also be firewall blocking the traffic
assuming you use windows, try installing the web plugin from this site. Use internet explorer as well.
your overall fix is to use iVMS-4200, plus you’ll need it to downgrade the firmware
