Why has a recent wifi installation interfered with my bridged Dahua security cameras and now they won't all display

[Just_AnotherUser]

I have Dahua security cameras in my home and a bridge to the cameras in my shed (all the same cameras). After a dead router we changed to TP-Link and also organised for wifi to be accessible in the shed. Since the change, the cameras in my house don't pick up the cameras in my shed. (I also now can't view them on my mobile phone but that's another problem).

When we logged into the system on a PC it showed a random IP address for the cameras in the shed. The IP addresses were manually changed and the cameras added but this didn't fix the problem of being able to recognise them as a device. We also noticed that instead of Port 1, 2, 3 etc the cameras that weren't being picked up from the shed had Port 37777. Each time it appeared the NVR in the office was interfering with the cameras in the shed.

We were able to view the house cameras when the ethernet cable was plugged in directly in the house. We disconnected the NVR in the house and connected straight into the cameras in the shed - they worked (the shed ones). The wifi also worked.

My question is why does it appear the NVR is blocking some of my cameras since getting wifi in the shed?

Nothings being blocked.

The cameras with the 10.1.1.105, .107, .108 addresses and 37777 port have been manually added instead of allowing them to migrate to the bottom pane by themselves. Probably not connected directly to the NVR ports.

Not sure I understand how the shed cameras are connected to your NVR? But unless they are plugged into the NVR ports direct, you shouldnt be using the 10.1.1.x range. Can’t manually assign those with success, that range is handed out by the NVR built in switch

If the 3 shed cameras are connected to an external switch, you should give them IPs on the network the switch is attached to. (Like 192.168.1.x) - assuming the switch and NVR are both on the same network/range
Then the NVR will see them and you can manually add them.

Side note:
Is that NVR screen from being connected direct with a cable to the NVR and a monitor? You should try to connect to the NVR using its web browser interface instead of that machine direct interface.
Just type in the IP of the NVR into a web browser
