As long as devices in one building can communicate with the other then there isn't a need for anything special there (as long as you use IP cameras). Any system should be able to handle this. Security camera NVR, VMS, DVR etc just need a data connection to the camera. If it's stable between your two buildings then treat the cameras like they're all on one LAN.
As long as you can power the cameras (poe injectors work) and the camera bandwidth isn't going to saturate your fiber connection between the two buildings treat them like nearly any other device on your network.
Again, my comment doesn't work for HD-Analog cameras, but if you're planning IP (as you probably should so you can use your existing infrastructure) then there's nothing to worry about.
Maybe we should take a step back since adding 34 channels of video on a shared network could be a considerable additional load.
Even assuming a VLAN, the fiber port will still need to handle the sum of the added video traffic in addition to what it has already. Will there be enough?

If you deploy a video server, where there are 34 cameras, dual NIC, you can use something like two layer 2 200watt+ switches, 10/100 ports, Gigabit uplink ports, (500each??) connected to the isolated NIC. Connect the other NIC to your data network. VLAN the cameras on the other side to another 2 layer switch on the 9 camera side. You would only be using two of the 3500 switch ports to do this, each configured for an isolated non-routed VLAN. This would only load your network with the 9 cameras, or probably at most .02% of a Gigabit network.
Use whatever brand of server you like (Dell, HP) with adequate storage on for the cameras you plan to deploy. (You would probably need 8+ TB of video storage, preferably in a RAID 5/6 config, just for these cameras to be installed, depending on location, resolution requirements, motion or continuous, light levels, etc). You can use software such as Exacq, Milestone, etc. This all depends on how you will use the system. Using something like a vendor specific server (for example, a Hikvision 64 channel 8 TB server would be probably about $5000) would work, if you only have basic recording and viewing needs. You would have to use Hikvision cameras ($200 interior, $800 exterior, $2000 PTZ - all depending on applications) A software based VMS server would probably run you the same cost, but you would need to add licenses, at $125-200 each normally. This would raise your cost by another $5000-8000. You could use devices like Husky or Exacqvision branded servers, but you can generally get more bang for your buck with your own custom servers.
You can use any PC as a workstation. Preferably with an independent video card.
