Intranet with multiple switches but no router - is this possible?

Hi, we're looking to connect three Ubiquity POE switches to each other using SFP's and fiber. This is to connect POE security cameras in three different locations to the same Network Video Recorder (this will be connected to one of the switches using a patch cord). Is this possible without a router in the mix somewhere? Simple picture is below...

(Switch A)---(Switch B & NVR)---(Switch C)

Thanks!
