Unifi/Ubiquiti
Unifi devices are kind of like a “prosumer” networking ecosystem. It’s a step up from an unmanaged network, but a step down from a legit network (think Sysco or similar). You can use it for a theater, but your probably shouldn’t use it for DOD. That said, for most things, it works great and the price is right. I'm personally a big fan
Some gotchas:
When you plug in a new network device, like a switch or WAP, you need to adopt it to your head-end (UDM). You can’t do this via the web interface, you have to do it via the iOS or Android app. This is the only dependency on handheld devices for setup. Everything else can be done via the web interface - which is pretty slick.
