Security system config

Wondering what security systems are being used to integrate to HA? I saw this and plan to ask the manufacturer if there is integration to home assistant.

Well incase anyone reads this. I spoke with them and everything does integrate with HA however you have to pay $39 a month for 12 MO for live monitoring service on top of the $99 for the hardware. If you cancel within the 12mo you have to return the hardware. All their live monitoring does is call you if the alarm is tripped to ask if you need them to call the police. I don’t feel I need this service and can do my own monitoring so I’m gonna pass.
