# AI security, access control and smart buildings

Make existing CCTV act like an extra team of guards, and make buildings respond to the people in them, with everything processed on-site.

**Who it’s for:** Facility and property managers, security managers and guard-service companies, warehouse operators, hotel and office operators, and building-automation integrators.

## Why Nabrio in buildings and security

- **Uses the cameras you have:** Nara adds AI to the IP cameras already installed.
- **Runs offline:** Everything runs on-premise, with no internet connection needed.
- **Acts on what it sees:** Nara drives doors, barriers, sirens and tower lights, and works with building platforms such as Home Assistant over HTTP or MQTT.
- **Alerts with evidence:** Alerts reach Teams, Telegram or email with images attached.

## Customer stories

- [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)
- [Lights and air-conditioning that follow the people in the room](https://nabrio.com/customers/occupancy-lighting-hvac.md) (An office and facility operator)

## Use cases

### Security

- [Intrusion and after-hours detection](https://nabrio.com/use-cases/intrusion-detection.md): People, vehicles, or animals in zones on a schedule → alarm, images to the guard's phone
- [Perimeter and gate monitoring at night](https://nabrio.com/use-cases/intrusion-detection.md): People detection at gates and fences in low light, without internet
- [Smart NVR / event recording](https://nabrio.com/use-cases/intrusion-detection.md): Save images and clips only when events happen; searchable log
- [Abandoned objects](https://nabrio.com/use-cases/intrusion-detection.md): A stationary unattended object in a zone longer than a set time
- [Asset removal (loss prevention)](https://nabrio.com/use-cases/intrusion-detection.md): Alert when a watched object leaves its position
- **Weapon detection**: Detect firearms and knives; track the people involved
- [Cross-camera person tracking](https://nabrio.com/use-cases/intrusion-detection.md): ReID follows a person across cameras and devices for investigations

### Access control

- [Face-recognition door access](https://nabrio.com/use-cases/face-recognition-access-control.md): Recognise enrolled people, with anti-spoofing (rejects photos and screens) → open the door through I/O
- [Licence-plate barrier control](https://nabrio.com/use-cases/licence-plate-recognition.md): Plate read + allow-list → open the barrier, log time in and out
- [Conditional entry (PPE, metal detector)](https://nabrio.com/use-cases/face-recognition-access-control.md): Combine vision and sensor results before opening the gate

### Occupancy and energy

- [Occupancy-based lighting and HVAC](https://nabrio.com/use-cases/occupancy-based-energy-control.md): Lights and air-conditioning run in empty rooms and zones.
- [Space and meeting-room utilisation](https://nabrio.com/use-cases/occupancy-based-energy-control.md): People counts and dwell time per room or desk area → utilisation dashboards, booked-but-empty alerts, input for space planning.

### Safety

- [Fire and smoke early warning](https://nabrio.com/use-cases/fire-and-smoke-detection.md): Camera-based detection in large or open spaces
- [Falls (elderly residents, hotels, lone workers)](https://nabrio.com/use-cases/fall-detection.md): Fall and lying-down detection → urgent alert
- [Blocked fire exits and corridors](https://nabrio.com/use-cases/danger-zone-monitoring.md): A stationary object in an exit zone → alert
- **Car park safety**: Bay occupancy, vehicle dwell time, people in restricted areas, fire and smoke

## Connects to your systems

IP cameras, doors, barriers, sirens and tower lights through digital I/O or Modbus, building platforms such as Home Assistant over HTTP or MQTT, and Teams, Telegram or email for alerts.

## Frequently asked questions

### What savings have customers seen?

One site security deployment mitigates 5–10 million THB of potential stock losses and saves 30,000 THB a month in guard costs.

### Does it work at night?

Yes. Our gate and entrance deployments detect people at night, processed locally without the internet.

### Can it open doors and barriers?

Yes. Nara opens doors and barriers through digital I/O when a face or licence plate is recognised and any other conditions are met.
