Connecting an NVR to the internet via my home network using Smarthub with Hybrid EE

[quattr020V]

I have recently had installed a cctv system. The nvr needs an internet connection, so the installer used a splitter  to tee into my home network cable which ran from the router to my computer windows 10 and my wife's computer Windows 11

Now the two computers cannot "see" each other, and the network has become Network 2.

Enquiries revealed that the nvr should have a dedicated internet connection. I have a single Broadband Smarthub 2 with a 4G Hybrid add on.

How can I create the dedicated connection for the nvr and restore the home network?

You don't need a dedicated internet connection, you simply need a dedicated Ethernet or WiFi connection back to the router. You can't use a 'splitter' to ' share' an Ethernet connection between a PC and an NVR.

Edit: are you sure it was a 'splitter' and not an Ethernet switch? I am also confused by your reference to a single cable from your router to 2 PCs

Thanks for prompt reply.

Yes I got that wrong. The router is based on my wife's computer, and there is one ethernet cable from the router to my computer.

re the nvr, at the moment the ethernet cables plug into a TP-Link 5 port desktop switch

I'm still confused as to how things are connected.

There should be 4 cables connected to the switch, one from the router, one to your PC, one to your wife's PC and one to the DVR.

Alternatively, one of other of the PCs might be directly connected to the router either via cable or WiFi.

 Hi Liquorice

After much grovelling about under desks etc, I have produced the following info:

Connections to the router.

The broadband wall socket.

The power supply

Yellow Ethernet to my wife's computer

Red Ethernet to the Hybrid unit to its assigned socket

White Ethernet originally directly connected to my computer

There are no remaining RJ45 sockets apart from the  WAN.

After the CCTV installer's work, at the other end of the White Ethernet in my office:

To the desktop switch:

The White ethernet cable from the router in port 1

A Dark Grey ethernet cable to my computer

A light Grey ethernet cable to the NVR

A power supply at the rear

Note that there are no spare LAN sockets on the router.

As a matter of interest,the 4G Hybrid panel never shows more than 1 blue bar.

Over  to you🤔

I believe a "new" network automatically defaults to Public, which prevents sharing. Try setting it to Public.

The WAN port on your router (assuming SH2) is dual purpose. Log onto the router at 192.168.1.254 & check the FTTP mode. If it's active disable it & you can then use the WAN port as LAN4. Depending on the physical layout you can then remove the switch & plug the NVR directly into LAN4.

Thanks Guru. I'll have a look at that.

Hi Guru

I checked the Hub Manager using my wife's computer as I can't see the router on mine.

 FTTP is off, and ethernet 4 connection is shown as an option for the wireless connection.

The nvr manual says:16. Isolate NVR and IP Camera Network
The network your NVR and IP camera resides on should not be the same network as your public
computer network. This will prevent any visitors or unwanted guests from getting access to the same
network the security system needs in order to function properly.

Our home network is set to Private.

The next step is to connect the NVR directly to the router on Ethernet 4.

I take it the NVR will be automatically assigned an IP address.

Meanwhile thanks to you both for your assistance.

LAN4 has nothing to do with wireless.

Your network isn't public.

The network needs to be set to private on each PC.

Yes, the router will provide an IP address unless the installer set it to manual.
