HELP - cannot connect Dahua IP camera to NVR

I would say set a new Password for NVR, then reset the Cameras.
Those Poe NVR's normally automatically initialize the Cameras with the NVR's password.
Btw you can plug your PC/Laptop into an Poe Port of the NVR and access the Cameras directly via Browser or Config Tool

I can't reset the cameras, because they don't have a button or any way to reset. But I will reset the NVR. Thanks for the tips

when you do like I said, it will ask/allow you to set the same Password for cameras if they are plugged into it.

Follow the PSA and it will work fine, change things, skip steps and it won’t.

After initial setup of the NVR, access it from then on via its web interface using the IP address you assign it in a browser.

There is absolutely no need for the config tool connecting Dahua cameras to a Dahua PoE NVR .
