What program to play the archive of video recordings from surveillance cameras?

Question

Video

Good afternoon, there was a huge problem. I can’t reproduce data from 4 surveillance cameras, the fact is that I have no experience in this. I tried about 20 preer and CMS for video surveillance, but none of the programs opened it.
Now I will describe what is available:
1. A hard disk with the Ext file system (I can’t say the version, since I ran it under Windows and only managed to open it through third-party software, I can clarify)
2. There are only 2 folders with files on the disk, in one folder files with DVR resolution (information with video info is attached below), into the second files with IDX resolution.

Thank you for your attention, I'm waiting for at least some kind of clue

Answer 1

I renamed the file to .264 extension, and it opened with the usual MPC-HC, though with image artifacts. Broken file, right?
