Each camera has its own analog connection wire. I am looking for a dvr box that I can connect to a home server and run something like Shinobi. I currently have this dvr box https://ellipsesecurity.com/product/hdtvi08b-tru-view-hd-tvi-8-channel-hd-security-dvr/ , but i don’t think it can automatically forward video to a home server
Use the existing (presumably coax) runs to pull Ethernet cables through the walls and replace them with IP cameras
