Exclusion zone
Excavations, plant swing radii and other hazards on construction sites are cordoned off; entry into the zone risks serious injury and must be caught immediately.

No alert — exclusion zone marked and clear, nobody near it.
Nothing wakes. Only the nanopower domain and the PIR are drawing.
How the camera spots it
Debris blowing across the site is cleared locally. People near the cordon are escalated, and Gen AI reasons about position relative to the barriers: a worker outside is fine, a person inside the keep-out area raises an alert.
How you would set it up
- Wake
- PIR wakes the camera; radar confirms a person- or vehicle-sized target before any capture
- Schedule
- Timed capture at the start and end of each shift. Heartbeat every 12 hours.
- On the camera
- Radar drops blowing debris and gives distance, so movement well outside the cordon is not escalated.
- Your criterion
Is anyone inside the fenced exclusion zone around the excavation? A person outside the barriers is fine.
