I’d expect more of the modern panels made within the past dozen years to run on a Linux based distro and have an easy access point on the local network to get to it’s intranet pages. Although I’d think on the cybersecurity side of things. Sometimes it would be better to keep the alarm system separate from the internet so it doesn’t get interference or exploited whereas as hacker would have complete control of it’s operations. It might also be possible to DDoS it as well which would make it inoperable if happened.
