I'm wanting x 6 50 inch televisions mounted on a office wall with the following functions...

1 or 2 monitors will have direct tv
1 or 2 will be showing remote cctv from a dvr offsite
1 or monitors will be showing database reports from an offsite server

The database report and cctv will be url/ip address feed, so what kind of equipment besides the televisions would I need?

Thanks for any help
