Good Morning,
If the SADP tool is not finding it on your router, please try creating a small private network using a switch.
Just hook the camera into the switch, get power to the camera (if this is not a PoE switch), and plug your computer into that same switch. Your PC will need a static IP since now there is nothing assigning IP addresses (this IP address can be on any range you want, 192.168.1.x, 10.1.1.x., etc)
Once you have the PC set for a static IP, run the SADP tool, and see if the camera gets picked up.
Please report findings, thank you.
