I'm dealing with similar issue using Starlink.
I recently set up a system in an are that has no wired internet available. The homeowner looked into Starlink at my suggestion.
His option was Hughesnet and it was really not worth having. Way too slow and too costly.
The Starlink has given us speed up to 150meg and so far not lower than 60meg.
We are not using an NVR, the home was per-wired with basic cable for analog so I installed a Hikvision oem 16ch 8mp DVR
Currently we are using Guarding Vision, a cloud based app to access the cameras. They have been working for about 3 months now and
we have had no down time. viewing on phones and i pads and all load quickly and we can get motion notifications as well.
Overall not bad to view and replay video.
My problem is that we normally monitor and make basic changes remotely for clients, but with Starlink, we can not connect using anything
like Ivms-4200 on a PC. Guarding Vision is only good vor remote viewing and palyback, nothing else.
I'm told you can not port forward with Starlink and there is no IP address to use to remote access the system.
I recently contacted noip.com but they had no experience with Starlink so they really couldn't help.
Making a 200 mile trip to make changes really doesn't work..
This is new to me and I'm out of options at this point so if anyone has a workaround, please let me know.
