Hi all, Long time, first time here. I've been looking at this stuff off and on for a number of years now, and have recently gotten serious about putting together a good, upgradeable camera system for my house. After reading the great advice here, I'm pretty ready to pull the trigger on the outdoor portion of my system. I will be purchasing the StarLight Dahua cameras (bullets and turrets) to begin. I'd also like to get a good managed switch so that i can isolate the cameras on their own network. Therein lies the source of my confusion. I had a few questions I was hoping you all can help me sort out. I read that I'd need a managed switch like the SRW248GP to do the network isolation that is best for security. Is this assertion correct, and will this switch allow me to isolate networks appropriately? I wanted an inexpensive option, hence the SRW248GP. Is this a good option for me, or would I be better served going another route? I really don't need all those ports and I do understand that there is an acoustic noise issue with this switch, but I'm OK with it. I have an older router that I wanted to use as the firewall and DHCP server connected directly to my cable modem. This device does not allow for an OpenVPN installation. Could I instead simply run OpenVPN on my Blue Iris box? Are there any tradeoffs here, and would I be better served purchasing a new router that natively supported OpenVPN? My house has a lot of dead spots. I would like to use old routers configured in 'AP mode' to act as wireless 'extensions' of my network. I understand that if I make them the same SSID with the same password that my devices will switch seamlessly. Is this correct? Where do I put the Blue Iris box in the topology below? I'd like to be able to access it from the outside via OpenVPN, and it's not clear to me where it should be placed. I'd think that it should be on the same subnet as the cameras, but want to ask more knowledgeable people. How does the switch allow for communication between VLAN10 and VLAN20? I've never worked with a managed switch before, so I'm at a bit of a loss on how it actually works. How does DHCP work on the two different subnets if the Cisco switch is in the middle? Will all DHCP requests be passed through to my initial router?
