Support for AlarmDotCom devices

I have an alarm.com system today that I want to remove and replace with Home Assistant. I would like to use the existing hardware, such as 2 thermostats, a door lock, and 7 cameras. I’ve read about the alarmdotcom integration and I assume it expects an alarm.com system is there to talk to? Can I use my existing alarm.com hardware if I remove the alarm.com panel?
