Trying to help out a friend. Everything has worked fine for the last year, until about a month ago. His current setup is:
(2) Dahua IPC-HDW4431C-A 4mp IP cameras
(1) Dahua 8ch 2014 NVR
Both were purchased on Amazon, so I'm not sure if he received the US or Chinese firmware
He asked me to come by because the cameras abruptly stopped working. I thought it was odd seeing a screen with one camera saying invalid username/password but showing a private IP like 10.1.1.71 as I originally helped setup the cameras with a 192 prefix. II verified both cameras have power by manually activating the IR cut filter. After a little troubleshooting, I brought both cameras home and ended up resetting them using the jumper wire method. With a default IP and password, I started with one camera, logging in via a web browser on my own network and reassigning an IP address like 192.168.1.224. I then unplugged the camera from my network and plugged it in to the NVR. While doing a 'device search' no cameras would be displayed. I tried manually adding the camera, but as soon as I click save, the NVR shows the basic black screen with IP address and saying invalid username and password (at this point it still shows the IP 10.1.1.71 or something close to that).
Having hard reset and being able to connect to my own network, while configuring it and such, I can't figure out why is NVR keeps changing the IP address of the camera? Any thoughts?
