Cat6 Local Area Network layout - advice needed please

[MrAubs]

Hi there, I'm in the process of setting up a small business and am planning on installing a small local area network that will run our cloud phones, computers, IP CCTV cameras and network printers. I've devised a layout for the network and attached an image, can anyone tell me if this layout is feasible and would work? We haven't planned on a server as all storage will be in the cloud and all of our software is cloud based too. Also should we be using Cat5e or Cat6 cabling? We're going to be having a 100MB leased line installed, so internet speeds shouldn't be a problem. I'm capable of installing the cabling myself, just want to make sure that this layout will work and shouldn't give me any bottlenecking issues etc. Thanks very much in advance for any advice given

When you have no local server and everything is in the cloud that only runs at 100m then you likely could use any design and it will work fine. As long as you use gigabit switches you will never be even close to overloading your internal network.
You could use 100m switches but there is not a huge difference in the price.

Since you are only running 1g you can use cat5e with no issues. Cat6 if you happen to find it cheaper. Make very sure you do not buy CCA (copper clad aluminum) since it is not a certified cable and has issues of random failures especially running PoE.

.....looking again at this you to a point do have a local server, your DVR. This means you likely should have most your switches be 1g. Your placement on the main switch is correct.
