Integrating Alarm with Home Assistant

Configuration
1

I’m looking for an alarm to integrate with HA. Curious if the below is possible and if so, who one would recommend:

  1. Ability to handle 49 zones
  2. Ability to have an arm stay mode for when at home that has no delay when alarm is tripped after arming
  3. Ability to arm with Alexa (e.g., say Alexa goodnight and Alexa signals HA to turn lights off and HA to arm stay no delay)
  4. Monitoring outside of HA (a company monitors alarm that is tripped and calls police)

Thanks for any recommendations.
