Hikvision NVR Goes Offline

[CCTVuser]

Could anyone please advise where I am going wrong, with the BT broadband connections for the Hikvision NVR's?

I have tried every combination of numbers advised in the NVR network setup, I now think the issue is with the BT hub. I have used the NVR on another fibre supplier, and using a Netgear router, and that worked fine.

The problem is, the system will work fine for a few hours, and then the Hikvision platform access will go offline. That's the platform I am using for remote access. I have setup DDNS with No-Ip as I have for many years, and again that works fine. when the NVR goes offline, DDNS connection is also lost.

I have set the IP as static, and the preferred DNS to 192.168.1.254. I have also tried many other combination of numbers there, 8.8.8.8, 8.8.4.4, 1.1.1.1, but still the system goes offline.

Could anyone please advise if there is a setting in the hub, or if BT block this access at all?

Many thanks in advance

Have you set up port forwarding for the NVR?

And the DDNS is that set up in the hub or the NVR?

We have a Hikvision 2 camera 4k system installed in 2015......

No sooner it was up and running we encountered issues with it going offline after a period of time. Found out the BT supplied router was overheating where it hadn't before, needing a reboot to restore the connection.

Ended up swapping out for a Draytek 2860ac router, no issues since.

Thank you for your reply.

Yes all that’s set up and works correctly. I also know it’s not the NVR, as the recorder was set up on another none BT network. The issue has started when connected to a BT hub 6, and this I’m 99% certain is the issue.

I originally set up with a Netgear hub, and it worked fine.

After digging around today, and contacting BT tech line (they had no idea whatsoever about anything I asked about) However I did speak to one very knowledgeable person from a CCTV supplier, and he thinks it could be IPVR6 related.

Anyone know how to disable that on the hub, as I have tried,  it will not disable?

The issue I have, BT are the line supplier, and they cannot give help, why am I paying for a service that has a tech team that can’t solve the problem with their equipment?

Anyone have an idea please?

Perhaps BT could answer the question about their system not working?
