Trying to gauge how much my little i7-4770S cpu can handle before an upgrade is needed. Right now, hovers around 50% running: 8 x 2MP and 3 x 4MP at 15FPS (I forget the total bitstream bits at this moment). I am not full time recording (surely, that takes up some CPU) as waiting for a 4pin power adapter to get my WD Purple 8TB running). And I maybe add in 2 more 4772's (4MP) cams in the near future. For a total of 13. #14 cam could be a doorbell cam if ever one comes out with POE (I wired my house this summer/fall and do not want to go WIFI for it).
