Any help would be greatly appreciated. If i bought 2 of these switches to run with BI Amazon.com: TP-Link 8-Port Fast Ethernet PoE Desktop Switch with 4-PoE Ports (TL-SF1008P): Electronics Say i had the two switches in remote locations of the house with 4 cameras wired to each. Then both switches wired to my office to router. Would i need the 10/100M or the gigabit model? If I wanted to add another 4 cameras down the road for a total of 12 can i buy a third switch & add it in? Also, is there a limit on how many switches you can have on a home network?
