What is the analogue of the Trassir video server?

Question

CCTV

There is a park of Hikvision cameras. Everything revolves on cheap Trassir'e.
But the number of cameras will increase dramatically and you need to change the server. There is no desire to buy Trassir until they start installing the OS on normal disks, and not on deshman flash drives that burn at any opportunity. I went to the site, there is a server for, say, 180 thousand for 128 cameras, in which the filling of an average home PC for 50 thousand and, in addition, an OS on a flash drive, is some kind of tin.
Yes, there is an option to build your own server and just buy tracer licenses for cameras, but it turns out to be a little expensive - this will be plan B, for lack of anything else.
Maybe someone uses some other server software similar to Trassir and can tell you what to look for.

Answer 1

Videonet, Intellect, Macroscope, Securos, Line.

Answer 2

Option 1: transfer the OS to your own, good flash drive?
Option 2: build a server and buy cameras from the officials so that the camera comes with a license "as a gift"

Answer 3

As an option - Xeoma. Somewhat specific software, but the key for the demo Pro version is easily provided upon request, you can evaluate the applicability. I test-drive, but a couple of moments forced to abandon it. The server part works on Win, Lin, I ran it on headless Debian 9.
