Possible VLAN to eliminate router traffic with Blue Iris?

I have an odd network in that part is in the house and part is in the detached garage and there is only 1 ethernet between the two that is run underground. Normally I would prefer to run a dual nic in the BI and have all the camera's fed out of that, but I'm not able to in this situation. I think right now everything it running through the router and my recordings are kind of choppy. I'd like to isolate the ip cams from the router but not sure what approach would be best. The two switches are TP Link TL-SG108PE managed switches. Is it possible to create a VLAN that would put all my BI and cams in isolation? would I still be able to remote via the app to BI if I were to do that?

What's the speed of this connection?

Based on your diagram - only internet traffic is going via the router.
Unless what you're referring to is when you are remotely accessing your network.
The cameras and the BI PC are all connected locally via the switches.

Internet connection? 300mbp. Interesting...for some reason I thought all the traffic would be going through the router in this setup...but I am showing my lack of knowledge I guess. In looking at the BI optimization wiki, it seemed to push towards a dual nic BI pc and all cameras feeding off of a switch that the 2nd nic is connected to in order to isolate them...I thought that was for better performance (which I thought was because of the router)...does that make sense?

We have seen some routers still attempt to route even in a setup like yours - if you unplug the router can your BI computer still see all the cameras? That is the first test.

But the other reason we dual NIC is so that the cameras are not on the same LAN as the internet because then they can be hacked. That is why we isolate them from the internet.

No - the cable connection between the house and office.
You said the video was choppy, so potential congestion on the trunk between them.
Assuming it's local access you're referring to, not access when you're away from the location.

So I just tested it...turns out my diagram was wrong...both switches were being fed out of the router...I changed it to what my diagram shows as I think that is better. After doing so, and unplugging the router, I still have local access to all the cameras with the BI desktop. So really, a VLAN would only benefit me for security, which would be good as well...not sure if my running both switches directly fed from the router had something to do with the choppy recorded video.

Yes, it is local access that is the issue. or rather the only time I'm looking at any recorded video and I experience the choppy recording.

Via the router? Hopefully that's the cause.
Even low-cost switches should achieve full-speed non-blocking performance on all ports across their backplane.
Less likely to be able to do that are the ethernet switch ports on some routers. Their primary task is the routing function.
