Using dedicated Network Card / Adapter to isolate cameras from Internet?

Post by oceanslider » Sat Jan 18, 2020 10:02 pm

I would like to learn about using a dedicated Network Card / Adapter to isolate my IP Cameras from talking directly to the internet.

Is anyone here doing this, willing to explain how they set it up?
Dedicated Blue Iris 5 PC : HP ProDesk i5-8500, 8gb RAM, 256gb M.2 SSD(for BI and Windows 10), 8tb drive shucked from WD EasyStore.
Two cameras so far: one IPC-HDW5231R-ZE and one IPC-T5442TM-AS, eventually looking to have about 6 or 7 cameras.

I think folks now use virtual networks using modern routers to isolate subnets but I am not 100% sure. Maybe research virtual nets.

But then I would need to buy another router. I have an ASUS RT- AC68U flashed with Merlin, but there is no way to create a VLAN with this router. It is a good router and I have OpenVPN setup on it for remote viewing.

There should be a way to setup a dedicated Network Adapter for just my IP Cams. But I'm not super network savvy. I could do it if I had instructions or a video tutorial.

This may not help if you are set on a 2nd network card but it lets you what other options there are.

I'm using a Ubiquiti system here and its very easy to deny internet access to any individual client or group of clients by creating a 'rule'.

If you want a separate physical network, you'd need a separate router to do the routing on that second network, wouldn't you? Really not sure, just asking.

I used to use Network Services Filter on my old ASUS (non-Merlin) to block internet access from my cameras.
I don't know if Merlin supports the same or not.

That's what I did because I have 1 wireless camera, as well as several wired cameras. I have the router use DHCP on the 2nd nic for that subnet. Worked well. It isolated my 'camera network' from the internet, and, from my normal use network.

BI could see cameras on both networks.

Create a rule in your router's firewall to deny access to the internet for each camera. Setup is different for every router, but if your router allows you to create firewall rules, this is by far the simplest way to do what you want to do.
