Ok then - the 10.1.x.x is your LAN address on the PC.
You'll need to have the NVR addressed as 10.x.x.x - first three numbers must match, last number must be different.
You will use that number to connect when you are on the same LAN (Local Area Network).
If you want to connect from off site - you will need to port forward your router, and then use your WAN (Wide Area Network or Internet) address. Easy way to find your WAN address is go to http://www.canyouseeme.org. This will show your internet address and also has a port checker. Use the port checker to make sure your router is forwarding correctly.
