Ref a setup required for approximately 300 Surveillance Cameras connected within a LAN. Around 250 Gigabit Optical Media Converters will bring in these cameras to Control Room. Please advise appropriate Cisco hardware to accomodate 300 IP cameras running on around 12Mbps which makes around 3.7Gbps total on 250 ports. The cameras then have to be distributed to network video recorders and several computers for recording and live monitoring. Please advise a system that is capable of accomodating around fity more cameras in future. Your help will be highly appreciated.
