Has anyone built out a self-hosted home alarm system? Something like ADT, but entirely self-hosted?

I'm wondering if this is possible with some combination of Frigate, Home Assistant, and something called Alarmo?

Or can a simple alarm system be created with just Frigate? I was thinking something simple like putting a camera inside my house when I leave. Then if any motion is detected inside of the house, activate a siren to scare potential burglars.

I have this exact configuration for my home and it works great. Door/window/indoor motion sensors trigger an alarm. Frigate cameras outside ping me if the alarm is active but don't trigger it outright. I also have a panic button to trigger it. I also have it tell me what triggered the alarm and have a list of the latest events. Lastly, make sure you setup an automation to let you know when batteries die. Typically happens after a couple years.
