Switch selection for Multi Floor Building Surveillance

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.

Thanks in advance for your help.

Hi Awais, I think the SG500 series may be good for you. It has a stack feature so you may manage every switch from a central location at the same time.

Here is the datasheet

Hi Awais, the purpose of the suggestion is for the access switch as well since it provides central management without multiple log in or changing physical location. Other models cannot participate in the stack and would not have a centralized management.

If you're looking to save a bit, you may want to look in to the smaller brother, the Sg300, they come in a 10 and 20 port variety if you don't need 24 or 48 port devices.

Hi Awais, either direction is fine, it depends on your limitation of cables. If you have the ability to run a CAT6 wire for the nearest switches to the control room then use fiber (gbic) for the other switches that are greater than lets say 225 feet away. (I am aware ethernet wire is a theoretical maximum of 329 feet but it is not recommended)

If you're running in to wire limitations then it may be most prudent to cascade 1 or 2 of the furthest switches in to one of the switches in the 'middle' and centrally join the other switches directly to the control room switch.

Dear Tom,

Fine, stackable Series 500 is OK in the Control Room. What do you recommend for Access switches on the floors?

Dear Tom,

thank you very much. I have just seen the 300 Series Datasheet and it has SG300-52P with 50 10/100/1000 PoE ports and 2 combo mini-GBIC ports.

I would rather use Series 500 in the control room.

We require around 20 Ports in the control room for workstations and NVR servers. What method you recommend for interconnectivity?

In series 500 Should I use a seperate up-link port for connecting to each of five series 300 switches? (i will require 5 up-link ports)

or it will go like 500 up-links to series 300 switch, this series 300 switch up-links to next series 300 switch and so on till the last switch?
