I have a network that I'm designing for an IP camera system with a parking garage and an office building. I need to use 4 24 port switches with multimode fiber running from the parking garage to the main buildings central data room and four 24 port switches in the main building with multimode fiber running to a central data room as well. So I would need a switch with 8 fiber ports and a few copper ports for the recording server and to "bridge" over to the customers network for access to the video server. My question is what switch do I use for the "core" switch. I'm having trouble with a model (Cisco or HP will work but HP is preferred).
