How it works

Local heron detection, recording and sound response.

tallGuard watches the pond on your Raspberry Pi. A confirmed heron detection can trigger recording and a configured sound, subject to your automatic response settings and the camera's view.

A heron bends toward a pond while tallGuard tracks it with a detection box.

Private by design

Your camera stays at the pond. Alerts come to you.

tallGuard runs on your Raspberry Pi and processes detection at the edge. It uses outbound, authenticated connections for alerts and updates, so your camera does not need to be exposed to the internet.

Detection: Runs locally
Hardware: Pi + Coral Edge TPU
Network: No port forwarding

Built for the pond

A practical early-warning system

Detection

Recognise herons at the edge

The on-device model is tuned to identify a heron without sending every camera frame to the cloud.

Fast, local inference

Evidence

Capture the event

Keep a useful record of detections with photos or recordings so you can understand when your pond is most at risk.

Review what happened

Response

Trigger a deterrent

tallGuard can play a configured deterrent sound when a heron is detected, while keeping a manual response within reach.
