Does the following link show your wireless camera system?

If so, I do not believe you will be able to monitor via Windows 10.
Primarily because you would need to be able to provide an individual network IP address to each camera via your network and then you would need the necessary Windows drivers to take the incoming camera data from the network to process and display the four images as shown on the included monitor.
As I read the specifications each camera has its own channel and those channels may or may not correspond (or interfere) with your existing wireless channels. Could well be some proprietary connectivity between the cameras and monitor.
So my overall sense is that it would not work out or would become extremely cumbersome to workaround. The software being the biggest issue.
