Still can't post it. It's at the Aventura Technologies website. Under Surveillance Products > Video Fiber Transmitters & Receivers 8 Channel Video Fiber Optic Transmitter/Receivers

Could I use something like this? Connecting the cameras to each BNC input, then use the extra fiber pairs to connect it to the video transceiver on the other end? I'll post the link in the next post, since the system isn't letting me.

Yeah, it's a 12 pair single mode fiber, and only two pairs are being used right now.

Ah, sorry I just figured it would have the same 100m limitations as a normal ethernet cable. I guess this makes things a little easier for me, thanks for the info. It's just that when talking to a project manager, he told me I could connect the cameras to a cctv hub/(or video server I guess) to connect it to both cores on both ends, that way I could take advantage of the existing fiber communication between the two buildings, thus saving on any cabling I'd have to do, or on an extra server. So there's absolutely no way, then?

So if I were to connect an analog camera with a balun on one end, and into a patch panel on another end, which then goes out to the DVR with a balun, it wouldn't work? How are these cameras usually connected in long cable runs? Because the building I have in mind currently has a couple of analog cameras using CAT5, and some are very far away from the DVR. So I'm wondering what they could be doing to extend the signal beyond CAT5's limitations?

Hi, I'm doing a paper about a proposal for integrating faraway cameras into an existing CCTV system. The network already hast a 3com 5500 core switch connected by a 200m fiber with a 3com 8800 core switch. each switch is on a separate building. the cctv system is on the building with the 8800 switch, it's a geovision system with more space for a few extra cameras. The cameras will have a BNC connector with a balun, but a CAT5 cable, so I can't just assign IPs to the cameras to communicate to the other side. Which is why I was thinking about having a small switch connected to the 5500 to communicate it with the other side. The only thing I'm having trouble wrapping my head around is how the communication will be done. The cameras can be connected to the smalls witch, which connects tot he 5500, which then goes to the 8800 through fiber. After that I guess there can be a cable that goes to another small switch which will be directly connected to the dvr/video server, and just take out the cables through the same ports the cameras were initially connected? It sounds kinda shaky in my head, not sure if it would really work. Any ideas? I'll attach I diagram of what I had planned, but any suggestions about the communication for these cameras is appreciated.
