Need advice with an infrastructure planning

Hey there,

We are planning to deploy star-type network in a new office building, with approximately 30 "beams" connecting to centeral switch. Some of this are dedicated to IP cameras (like 8 switches with 90 cameras in total). My question is what kind of bandwith/bottleneck problems are possible here, how do you guys integrate surveillance traffic in to your networks?
All switches are with all 1G ports, cameras is 5MP (actuall transmition quality is unknow at the moment) User traffic per switch rather low around 10Mpbs
At the moment we are looking at c9200 and c9300 as a hardware for this network

Thanks
