# Camera-based fire and smoke detection

Conventional smoke detectors react late in large or open spaces. Nara watches your existing IP cameras for flames and smoke, sends an immediate alert with an image to the control room, Teams or Telegram, and can switch on a tower light or siren.

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

## The problem

Conventional smoke detectors react late in large or open spaces such as warehouses, car parks and atriums.

## How it works

- **Input:** Existing IP cameras
- **Process:** Fire and smoke detection model
- **Action:** Immediate alert with an image to the control room, Teams or Telegram, plus a tower light or siren

Nara runs its bundled fire and smoke model on your camera streams. When it sees flames or smoke, it sends an alert with the image to the control room, Microsoft Teams, Telegram or email, can switch a tower light or siren, and saves the event for later review.

## What you need

- IP cameras covering the space
- A PC, server or NVIDIA Jetson running Nara
- Optional: a tower light or siren

## Nara building blocks

- Camera nodes
- Fire and smoke detection
- Notifications (Teams, Telegram, email)
- Tower light
- Image export
- Database table

## What it improves

- Time to detection
- Coverage of open areas
- Evidence for incidents

## Where it runs

- [Smart alarms that mitigate 5–10 million THB in potential stock losses](https://nabrio.com/customers/site-security-monitoring.md) (Industrial and commercial sites, several deployments)

## Frequently asked questions

### Does it replace our fire alarm system?

No. It adds camera-based early warning on top of your existing systems, which helps in large or open spaces where detectors react late.

### Can we use the cameras we already have?

Usually, yes. Nara reads standard IP cameras over RTSP, as well as Basler industrial cameras, USB webcams and video files.
