I'm getting another security cam system soon. I've been using geovision for decades and cheap analog cams. I have an I-7 pc with 16g of ram, so I think it may be powerful enough for Blue Iris. I'm a gadget freak, so I know I would love BI. My question is, how do I hook up cameras to the PC? I have a dvr card in my PC now, so it's obvious how to hook up cams as with a NVR. I know I would need a POE switch, but how to hook up the video cable to pc. I'm sure BI has the audio capability as long as the cam has a mic right? thanks Randy aka groran ( means big randy in french)
