# Fall and man-down detection

Nara detects when a person falls or stays lying down for longer than a set time, and sends an urgent alert with the location and an image. It helps protect lone workers, elderly residents, hotel guests and people in public spaces.

- What it takes: Ready to configure. Works with Nara’s built-in models. You set up the zones, rules and outputs.

## The problem

A person who has collapsed or fallen, especially when alone, may not be found quickly.

## How it works

- **Input:** Camera over the area
- **Process:** Fall detection (pose action model) and lying-down detection held for longer than a set time
- **Action:** Urgent alert with the location and an image

Nara estimates each person’s body pose and runs a fall-recognition model on it. A timer confirms that the person is still lying down after a set time, which filters out people who get straight back up. The alert goes out with the camera location and an image.

## What you need

- Cameras covering the area
- A PC, server or NVIDIA Jetson running Nara

## Nara building blocks

- Camera nodes
- People detection
- Pose estimation
- Action recognition (fall)
- Timers
- Notifications
- Database table

AI models: [Pose estimation](https://nabrio.com/nara/ai-models.md), [Action and behaviour recognition](https://nabrio.com/nara/ai-models.md), [People detection](https://nabrio.com/nara/ai-models.md)

## What it improves

- Response time
- Lone-worker safety
- Incident records

## Frequently asked questions

### Does it identify people?

No. Fall detection works from body pose, not from faces.

### Does any video leave the site?

No. Nara processes video on your own hardware. Data is sent elsewhere only if you build a flow that sends it, for example an alert to your own MQTT broker.
