Heck you can even cobble stuff together with Home Assistants and various door/window/presence/water/humidity sensors. I was able to build a notification system when doors, windows, or fence gates are open. Same with panic buttons that alert my SO if any of us need assistance when putting kids to bed without whipping out the phones.

All of that can be loaded into HASS using a $26 Sonoff Zigbee dongle and various Zigbee devices like Aqara and others.

ADT; there’s a program through my employer where employees get deals and so I made first contact with them. I chatted with a salesperson who walked me through a sign up process before I could ask any questions (I made contact saying I wanted to inquire about services and then said we couldn’t talk until he collected all my information).

He said normally it’s $100/mo but with this deal, it’s $75/mo.

No thanks. $900/yr to $1200/yr + installation fee for home security kinda stinks. I was told the equipment wouldn’t work if I didn’t have the subscription.

I’m sure I was taken for a ride too, being told false information (the equipment really wouldn’t work? It’s really $75/mo?). I indeed felt like I was being treated like a mark. At the end I said delete my information but honestly I doubt they did. But who cares because now I got myself into this pretty fun world of home automation and security through Home Assistant and self hosting.

I think they're referring to Home Assistant, that's what they found

Have you looked at Konnected? Really great if you already have a system installed but dead like I do.

Frigate is worth looking at as well if you have RTSP cameras as part of your security solution.
