Multi door entry system

[Greenarmy]

I was working on a small door entry system today (4 flats ). It got me thinking , that say it was 16+ flats system , how would you go about dealing with the 16+ cables at the main entrance . Obviously a junction box system would probably be required , but was wondering how to over come that and keeping it neat?
Was just wondering if folk on here have had to overcome this in the past , and what system/materials they used.
I appreciate that now the modern way Is probably wireless . ( the one I was working on was existing )
TIA for any insight into this , I just couldn't think of way without it being a bit of dogs dinner
Cheers

Take one multi core from door station and junction box DP on each floor in a secure area or there are also systems that use data so you dont need all the cables
