Nevermind, obviously was wrong place to post this, going back to other site for help.... __ Hi there, I'm slowly trying to get a small 24/7 system together as I have funds. I bought a Lenovo ThinkCentre M73 (500 GB, Intel Core i3 4th Gen, 3.3 GHz, 4GB Ram) with Windows 10 Pro off of Ebay for $60.65. I had a monitor and keyboard/mouse from an older computer. FINALLY got that all set up and going, downloaded Blue Iris demo. I bought a TEKEMPIRE camera from Empire Technology off of AliExpress, IPC-HDW2231R-ZS 2MP Starlight IR Eyeball Network Camera 2.7~13.5mm varifocal lens, for $125.00 I have a Xfinity Internet (60Mbps download/5 Mbps upload), a cable modem ARRIS SURFboard SB6190 DOCSIS 3.0 Cable Modem, and Google OnHub Wifi Router. I bought a 35 foot Cat 5E ethernet cable to hook the Wifi router's one ethernet port to the computer. So, What kind of PoE switch or injector would be recommended - I would like at least 4 ports, Ideally 8 or 12, to expand the number of cameras over time.... (I know the computer is underpowered for 8 or 12 cameras, but by the time I reach that problem, I will have gotten an upgrade on the computer, hopefully). And where would I put the switch? I would be great if it was after the Google OnHub, as that seems to be my security point currently... I know I don't know much, thank you for any advice you can give me!
