Hello everyone,
I am planning a high-reliability security “Inner Ring” for a property with a 23m x 19m perimeter. I intend to move to Home Assistant soon, but I have a strict requirement: the core deterrents must remain 100% functional even if the HA server is offline.
The Goal:
- Detection: Detect intruders approaching the house within a 6m zone along the 23m and 19m walls.
- Pet Immunity: Must reliably ignore foxes and cats (PIR/Microwave/Dual-beam).
- Local Deterrence: Motion should instantly trigger outdoor floodlights via a local hardware link (e.g., Shelly relay or alarm panel output) to ensure operation during server downtime.
- AI Verification: Once lights are on, AI-integrated Reolink cameras will identify if it’s a “Person.”
- Escalation: If a person is confirmed, the system will then send push notifications and trigger a full alarm/siren.
The Challenge: Uneven House Shape My house has an uneven, non-linear shape , which makes traditional curtain sensors unsuitable. I am looking to catch people as they enter the garden area, roughly 6 meters out from the perimeter, rather than waiting for them to be right against the building.
I’d love to hear from anyone who has built a “fail-secure” perimeter that balances “dumb” reliability with “smart” AI verification. Which can work regardless HA running, but may integrate in HA when running
