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.

[ 01 ]The problem

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

How it works

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.

Works with Nara’s built-in models. You set up the zones, rules and outputs. Site-specific PPE can be trained in Reva.

What you need

FAQ

Questions, answered.

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.
