I am wanting to install security cameras at my home. I want them connected to my internet. I have a cable modem connected to a wifi router in the living room. I want to run the cables from the cameras into another room opposite the living room. Can I connect the camera's dvr to a secondary Wi-Fi router in the bedroom and have that router wirelessly connect to modem in living room using the same network? Or would the dvr's Ethernet cable have to be plugged directly into router that's connected to modem in living room? Just want to keep it simple.
