I currently have an ADT system and am looking at ditching it for a HA green with zigbee adapter and doing motion sensors, door/window sensors, smoke alarms, etc over zigbee in HA. The roommate would like cameras and i would like something that doesnt require an account on a company servers that could go bankrupt or phone home. Any suggestions?

Edit: While I doubt it, would it be possible to continue using the ADT sensors with HA instead of having to replace them all? I am assuming they are proprietary garbage and won’t work, but being proved wrong would not be a bad thing.

edit 2: my idea so far

• HA Green (currently running on a Pi 4 just to get a feel for HAOS)
• Reolink home hub (for managing battery wireless cams and storing video recordings
• reolink Argus 3E cameras and possibly the doorbell (they detect motion, stream video, and have a floodlight which may get exposed to HA as entities under each cam device)
• HA ZBT-1 (for zigbee/matter devices)
• zigbee door/window contact sensors
