I have an older Emachines desktop with WIN7 on it that i would like to use as a in home camera viewer, but, i dont want to connect the camera to my router, mainly due to provider restrictions, but, also because i dont need an app or a way to view it remotely, and, i already have the PC set up to use 2 indoor webcams with it, so, what i would like to know is, if i get an outdoor camera, can i install a second ethernet card in the PC, and use that to connect to the camera without losing the internet connection on the PC? If so, how do i set it up so one card reads the camera, and one works for the internet? The internet side isnt as critical, since i only keep it online for updates, and to use as a backup in case something happens to my main PC, but, if possible, i would like it set up so i dont have to switch from the camera to the internet cable when i do need to hook it up online. A lesser question, could i use multiple ethernet cards, or possibly a dual port card, and connect more than one camera? None of the cameras would be recording, just set up so i can see if someone is outside.
