Dog worrying livestock
Loose dogs chase, injure and kill sheep, especially in lambing season; owners are often unaware and the farmer usually finds the aftermath rather than the attack.
No alert — flock grazing peacefully (same camera as Sheep rustling).
Nothing wakes. Only the nanopower domain and the PIR are drawing.
The grazing flock is the baseline. Small wildlife is cleared locally. Any dog in the field is escalated, and Gen AI judges intent and effect: a dog on a lead with the flock calm is cleared, while a dog off the lead chasing a scattering flock raises an immediate alert so the farmer can intervene.
- Wake
- PIR wakes the camera; radar confirms a dog- or person-sized target moving fast
- Schedule
- Timed capture at dawn and dusk. Heartbeat every 24 hours.
- On the camera
- Radar drops the grazing sheep by their slow movement and small wildlife by size. Edge AI drops frames with no dog.
- Your criterion
Is there a dog in the field? Is it on a lead with the flock calm, or loose and chasing the sheep?
