Repurposing Digital Life Camera

Previous person in home left me with their old digital life network camera (OC432). I would like to connect it to my network via the PoE adapters WPS function. There are no issues with my internet connection WiFi and Ethernet are fine through Modem and another router I have in another room. When I first attempted this I was able to view the device details in my modem settings. Initially I was able to connect to the Network Camera via WPS and opened the Cam in the browser by entering the IP of the camera. At this point I saw the device in the modem settings and it listed it as 'connected'. I was prompted with a username and password when viewing the network cam in browser, which I had no way of knowing since previous owner didn't know. I did some research and made the mistake of doing a reset on the camera device itself. Now that I reset it, I am unable to establish a connection to the PoE adapter via WPS and the device is no longer listed in the modem settings on one machine. On another machine (connected via ethernet to my router in another room) will sometimes show the device as present, but it(router) will not connect with it either.

I have tried the basics. There is power to the camera. Green light is on and power-ethernet cord works. I have tried to connect the camera close to both the modem and the other router. Distance is not an issue. I also contacted ATT connect tech about this issue. All they did was try and sell me a service to remote connect to my desktop to fix the issue. I am not interested in that. If the issue can be fixed by remote connection, shouldn't I be able to do it myself or does the tech have some passwords that I would need in order to fix this issue? Im not the smartest on a computer when it comes to networking, but I have a little experience and am able to learn. I would like to solve this issue myself and not pay $50 for someone I dont know to connect to my machine. Has anyone had this issue? If so is there any documentation you can refer me to so I can do this myself?
