I just set up a system with 16 Hikvision cams, (4-2332's & 12-2032's), and love it; however the computer I'm using to live view the cameras barley has the brawn to handle previewing 4 of them at a time. (It's a 3-4 year old Dell with an i3 that I wiped clean and reinstalled Windows 7 just to live view with iVMS-4200). So I was hoping that you guys could help me with some specs as to what I would need or will worked to decode all 16 cameras (1080p, 25-30fps, bitrate ~4,000) at once? Thanks in advance!
