I would actually look at both, a cheapish router with at least 6 ports (and make sure it is GigE not 100meg) and a nas, 2 bay minimum so you can mirror it for some data protection.

Then jump into the router configuration and put everything on a static IP address. That would make mounting a share on the NAS as a network drive on all three machines easy, you can then set the PC's up to save directly onto the NAS, where you can fish the images off from the third to do what you want with.

I am doing something like that at the moment playing around with practice timelapses, a laptop running Backyard EOS is writing the images direct to my NAS as they are taken (And I use Teamviewer to do anything required on the remote machine) so I can look at the images from inside the house where it is warm! I am hoping to do a bit more remote work and hopefully have the imaging laptop inside the house running remote USB ports shared form a Raspberry Pi at the camera end. What I am doing now demands a wired ethernet connection, sharing USB ports will be even more demanding, hopefully the network speed out there is enough as my current lead length is limiting it to 100meg.
