Hardened switches for edge devices are getting to be more popular. These days, we need things like built in OTDRs for fiber tamper monitoring, as well as baseline monitoring and port protection.

Something that I have seen in the lab over the years that needs to be mentioned to this audience about the actual NIC chips in play.
In general, some NIC chips are better than others in getting the data into the system.
Intel ones are the best but there are a couple of specific ones that need to be avoided for the camera feeds. Be sure to use those for the command and client comms only.
They are 82579, i219, i218, i217 as they are half speed internally and do affect the system performance. Below is an example from the i219 documentation.
So when you are connecting up you camera NICs, be aware of these and either add another NIC card or if available, use another NIC on the motherboard that uses a different NIC chip.
