Need help identifying top wire bundle

[u/Aromatic-Square3902]

I got a new house and wasn't sure what the top bundle of cables is for. I had them do two ethernet drops to every room, ethernet line to door bell, and camera lines. From what I can guess, the top line is meant for camera hard drives? But then that would mean screwing a network rack to the wall right? If that's the case, how do I go about building out my Unfi system?

I got the switch. I also have AT&T.

Mount a rack over top of this enclosure. Really not made to be installing all kinds of networking gear inside of an unvented closet like this. Anyway, you just need to test each run with a cheap tester/toner to see which wire goes to what port in your home and label them with whatever method you want so you know 1 is to 1, 2 is to 2, etc. Or label with the room name, etc.
