I've been using Ubiquiti/Unifi for my brewery setup (cameras, several private networks, phone tree stuff). It comes with some pretty solid management software accessible through the local network, but under the hood, everything's just running Alpine. There's a bit of a learning curve if you keep the management software installed (firmware updates wipe out the crontab, for example), but you can customize it pretty aggressively if you know your way around a terminal.
