New NVR I lost 5 cameras on a remote Poe switch.

[tubac]

Bought a new NVR after my old NVR died. Same model as the old one.
Somehow I lost 5 cameras on a remote Poe switch.All my cameras on the NVR are operating fine but the ones in my garage are not, I tried to add them but all say “failed to find the network host” with the ip numbers of each camera.
I have a Ethernet cable going from my router in the house hardwired to a router in my garage where the five cams reside. Any suggestions?

All my cameras on the NVR are operating fine

Are these connected to PoE ports on the NVR?
If so -

the ones in my garage are not

On the old NVR, had you changed 5 PoE ports to connect to the LAN-connected cameras by changing the mode to Plug&Play instead of Manual, and specifying the LAN IP address of the camera as the target?

Not that I remember.
How do I do that? Through the NVR’s interface?

SHow us a picture of your NVR camera Registration page

On Dahua NVRs as long as the remote switch is on your LAN same as your NVR, the cameras would be recognized in the top pane and can be manually added on the camera registration page..

If you can't see them , its possible A) your switch, or the connection to it, has gone bad or B) something changed on your home network router

Ok I’ve included a photo of the screen. As you can see I deleted a camera above in the search box. If I add it it stays red.

Whenever I add a camera I get the red circle. To fix it I have to edit the camera and type the password again. Then it turns to green. Doesn't matter that I enter the password correctly the first time.

Tried that , did not work for me,
But thanks

Not sure Im following what you did but,... on the bottom the two cameras showing red, D2, D3, are using the wrong port for internal PoE ports. (10.1.1.x)
37777 should only be used for cameras on an external switch not being connected to the internal switch.
Usually when they show as port 37777 at bottom its because they were manually pushed or added there. On cameras using the internal PoE ports of the NVR, they should be allowed to migrate to the bottom pane by themselves.

Are D2, D3 on an external switch? And if so, what is that external switch plugged into at the NVR? a PoE port or the NVR LAN port?

Looks ot me like some unnecessary network tricks are being applied and need unfucked

 

[tubac]

Oh, thank you for the reply- this really needs to be unfuckek
Yes all the cams offline are on an external POE switch The switch
Is hardwired into an apple AirPort Extreme.in a remote location ( my garage)
The Extreme is hardwired into another AirPort Extreme in my house and then the NVR.
Any ideas will be appreciated!

 

[bigredfish]

Does the last Extreme connect to the NVR LAN port, ...not a PoE port I hope..?

What about D4? Is it also on that switch?

Basically if they are on the external switch they shouldnt have 10.1.1.x IP's at all.

 

[Broachoski]

Is your NVR LAN and router on the same subnet.......192.168.x/xxx. ?
Those 10.1.1.xx addresses are given by the NVR 's POE ports.

You must have applied some change in the old NVR that allowed network hosts to be found rather than the current " failed to find the network host" error messages.
Unfuckingfortunately we don't we a config file backed up to try to apply to new device. ( might not work anyway if firmware is different enough)

/me goes to NVR and backs up his config file...
D2 and D3 might need to be looked at in the cam gui to see what the DHCP/ Static Ip settings are like.
It appears they have or had a POE switch connection before using 37777, but their IP's are messed up.
If, in fact d2 and 3 are local to the NVR, they should not be showing port 37777,
But I suspect they are remote.

All my cams are on a seperate Switch even though i have POE ports on the NVR....for what ever reason, my network access to the cams is very responsive via the switch versus the NVR internal POE with its 80Mbps ( maybe not even full Duplex) bandwidth cap.

 

[bigredfish]

So if D4 is on that same external switch, and it’s working and correctly assigned a 192x address from the router, D2 and D3 should look the same.

Fastest way out of the mess is to 1) delete D2,D3 from the Reg page, 2) default D2/D3 by either their GUI or the onboard factory default button, while connected. They should be assigned a 192 address.
Then connect the switch back to the NVR, discover them, and manually add to the bottom pane.

8 cams are on the NVR’s built in Poe switch.
The other five cameras are on a remote Poe switch in my garage . Those 5 cameras are the ones that are out. It’s wired together like this:
The NVR is connected to a switch. Also in that switch are a cable

Let me start that again...

In my house the NVR is connected to a switch. Also on that switch are a cable to an Airport Extreme router and a cable to the Poe switch in
the garage. From the Poe switch it goes to another Airport extreme which provides wifi to the garage.
All my cameras are on the 10.1.1x scheme.

 

[bigredfish]

They should not be and D4 isnt.
D4 is correct if connected to an external switch.
D2, D3 are not.

You shouldnt have external switch attached cams using the same 10.1.1.x network that the internal NVR PoE port cams are using

 

[Flintstone61]

10.1.1.x hosts in a 192.168.X.x. network will not be found.
garage cams should probably be in the 192.168.x.x scheme to be brought into an NVR with a 192.168.x.x address.
what is the iP address of the NVR

 

[Flintstone61]

NVR and garage cams need to be matching IP schemes.
Internal IP cams ( plugged into NVR) would default to 10.x.x.x as thats the New out of the box default IP scheme of the internal network of the POE NVR
they are on thier own network inside the NVR.
