How Would You Connect Network Switches For a Large 5 Building Video Surveillance System?

We are designing a video surveillance system for a large five-building office complex. Buildings are numbered 1, 2, 3, 4,and 5. Security monitoring station and VMS server will be in Building 3. Will be installing Cisco SG350-28MP Gigabit switches in each building. Plan to interconnect the five switches using fiber-optic cables between the uplink ports on each switch.

I have a question about how a system integrator would go about interconnecting these switches. Would you daisy-chain between switches (go from 1 to 2 to 3 to 4 to 5)?; or would you use a star configuration to the central switch (1 to 3, 2 to 3, 4 to 3, 5 to 3)? If using the first method, would you run a return loop from the first switch to the last switch (1 to 5) to provide redundancy? Or would you use a completely different method altogether?

I would love to get your opinion. Thanks.
