At your central location use a Patch Panel bro, not keystone's..

and PunchDown's are much more robust and reliable than crimp connections.. the weakest connection point in the link is going to be the crimp end you terminate at the cameras. pro's would rather use punchdown's on both ends and pre-fabricated cables for the device connections (though for IPC installs everyone crimps the camera end for good reasons).. dont get more solid connections than that. not to mention that its so much faster to roll out than
crimping hundreds of ends.
a bunch of 1ft cat6 patch cables are cheap, and look proper when patched into your main switch.. can even color coordinate if you want to indicate PoE devices or various segments of vlans.
