Personally if I have to go into an 'alarm' ecosystem I'd go with Alarm.com if you're serious about paying for monitoring.
My favorite vendor is https://suretyhome.com/ - they have reasonable costs to get an alarm panel running with monitoring and all the normal integrations.
(I personally use an older Honeywell Vista security system that's been integrated into ADC via a communicator. The sky's the limit!)
I am effectively a customer of alarm.com but not sure how. They seem to be a bundler or backend provider (sort of like a service OEM) for various branded alarm systems. Is there any technical material that explains what they do, and provides more visibility into the ecosystem?
