Home Security System

I setup a home security system using Blue Iris. I am using a 24/7 continuous recording, non-subscritption solution. All my cameras are on their own subnet and have no access to the internet for optimal security. I can access the cameras remotely using a secure Wirguard VPN tunnel. This all works great remotly because I have Google Fiber, which has a Gigabit up and down link. Blue Iris is the best Security System software out there but it only runs on Windows. I would prefer that it ran on Linux, because Windows is a resource hog.
