Switch recommendations for a multi level building.

[PsychoMantis 0]

Hello,

I'm designing a project for a 15 floor building with control room in the basement. Most floors have 6~8 cameras with a mix of SD and HD resolutions. I want to use a PoE switch that may serve three floors, one floor on which this switch is placed and also one floor above and one floor below.

Max bandwidth per floor (including possible future expansion) would be around 60Mbps max.

Please advise what cisco switch(s) I should use at floor, what switch I should have as the core switch and what switch I should place between the core switch and Monitoring Stations/NVRs.
