Thank you the folks who helped out. I'm looking into Frigate + Alarmo with Amcrest hardware.
Home Automation
Discussion about general home automation ideas and projects, home automation protocols like Z-wave, Zigbee, Matter, etc, and home automation software and hubs like HomeSeer, Home Assistant, OpenHAB, Homey.
Frigate + Alarmo (a Home Assistant integration) would fit your needs almost perfectly. You can integrate various IP cameras with Frigate, including non-Chinese brands.
Alarmo will work for the sensors that aren't cameras.
It looks Luke the Frigate website is recommending chinese Dahua cameras?
Their recommendations are less brand related and more related to compatibility with Frigate. I use Reolink, personally, but there are plenty of non-chinese brands that are compatible (such as Amcrest). Really, any camera with RTSP should work. OVINF support is a bonus.
