I currently have a campus that gets service from two ISP's that are each connected to their own router. The ISP's ingress and their routers are in different buildings on the campus. The buildings are not networked currently.
I have a requirement to install cameras across campus and have those networked into a single NVR and accessed by a browser anywhere on campus. There is no other requirement for load balancing across ISP's or need for redundancy. The only requirement is to receive video feed from the cameras to the NVR and play/replay on a computer browser on either network.
From a physical wiring standpoint, I can easily connect the networks from a switch in one building to a switch in another. I cannot so easily connect the two routers together directly without going through a switch. Any ideas on a fairly simple solution to this problem would be appreciated.
