In that case I would advise installing a router there with Tailscale support (something running pfSense or OpnSense would do it). Configure that router as an "exit node" in your Tailscale network. You should change the LAN IP address range to be unique, something you aren't using anywhere else, like
192.168.176.X.
Then by connecting other devices to the same Tailscale network, you will be able to connect remotely to view the cameras through the Hikvision NVR. You'll also have the option to add a
Blue Iris machine. I would NOT make it a laptop. Make it a desktop or mini PC and configure it to power on automatically after power loss. Also consider plugging it into a "smart plug" controllable via WiFi and an app so you can remotely reboot the PC in case it goes unresponsive.
If you have a Blue Iris machine running there, something I like to do is have another Blue Iris machine offsite pull a heavily compressed "All cameras" stream from it 24/7 and record it continuously. That way if the remote machine is inaccessible for any reason, you have an archive of the events leading up to its disconnection.
I am currently doing that for two remote BI systems with configurations like this:
The "Main" stream path in my example is:
/video/index/2.0?w=1280&h=720&stream=0&q=20&kbps=192&fps=1&audio=0&gop=4 but that is really very low image quality. Depending on your needs you might increase some of the parameters. The key is to use a fairly low bit rate.
Here are parameters for a 1080p stream up to 1 Mbps bit rate with a frame rate of 2 FPS (helps keep the quality fairly good even with the low bit rate), and a keyframe every 1 minute (the long "gop"/"i-frame interval" is also very important for keeping the quality good at low bit rate).
/video/index/2.0?w=1920&h=1080&stream=0&q=40&kbps=1000&fps=2&audio=0&gop=120
1 Mbps bit rate is about 330 GB of data usage per month so it would work pretty great on Starlink assuming it is "unlimited" in that area. But I would advise making sure the fiber ISP is used normally because that is a more responsible use of resources than streaming 24/7 over Starlink which is a much more limited shared resource.
