Depends on the hardware what the connected "automation" is.
The panels can be GE/UTC, such as Caddx or GE/ITI or 2Gig or anyone else. Basically, I'd say it's anyone on their "supported" hardware and features they wish to offer as a dealer.
Say I'm an Alarm.com dealer and I want to offer panel X only and not ABCXYZ, since I'm a dealer, I don't have to, but my X brand panel is on the supported hardware for their web application and business model, so I decide what I choose to sell you and your alarm is monitored and able to be controlled via their web head end.
