# PPE detection with your existing cameras

Nara checks every person in view for the PPE your site requires, such as helmets, vests, masks, hairnets, gloves and coats. Missing PPE triggers a local alarm and a supervisor alert with an evidence image, compliance rates appear on a dashboard, and an entry gate can open only when PPE is verified.

- What it takes: Ready to configure. Works with Nara’s built-in models. You set up the zones, rules and outputs. Site-specific PPE can be trained in Reva.

## The problem

PPE rules (helmets, vests, masks, hairnets, gloves, coats) are hard to enforce at all times in every area.

## How it works

- **Input:** Cameras over entrances, lines and hygiene zones
- **Process:** Detect each person and their PPE items
- **Action:** Local alarm (tower light, speaker), supervisor alert with an evidence image, compliance dashboard

Nara detects each person and checks the PPE items required in that zone. When something is missing, it switches a tower light or speaker, notifies the supervisor on Teams, Telegram or email with an evidence image, and records the event. Compliance rates build up on the dashboard for audits. At an entry, the same check can control the gate.

## What you need

- IP cameras covering entrances, lines or hygiene zones
- A PC, server or NVIDIA Jetson running Nara
- Optional: a tower light, speaker or gate controller

## Frequently asked questions

### Does it need internet?

No. Our PPE deployments process everything locally, with no internet connection.

### Can it control an entry gate?

Yes. At PepsiCo, Nara opens the entry gate only when the required PPE is detected and the metal detector is clear.

### Can it detect PPE specific to our site?

Common PPE is built in. Site-specific items can be trained in Reva.
