Sentry I — Smart access control.More than access control.

No servers. No complex wiring. Just connect power and you're done. A smart device that works offline and connects whenever it likes.

MORE

Everything you need. Nothing you don't.

Sentry I is designed for reliability. Every component has a purpose.

Works offline

Full functionality without an internet connection. Data syncs as soon as the network is back.

Easy installation

Connect the power and the door — the device is ready to go in less than 15 minutes.

Single-use keys

Every entry uses a single-use cryptographic key with end-to-end encryption. Your phone is the primary way in — cards only when needed.

Built-in relay

An integrated relay controls an electric lock directly, with no extra modules.

Cloud sync

Automatic sync with the PRIMO Manager platform over Wi-Fi.

Access management

Define who can get in, when and where — all from a single interface.

The engineering inside

Every detail is designed with purpose — from the connectors to the encryption. Simple installation, advanced technology.

The same hardware adapts to every environment. From home to hotel, Sentry I is the chameleon of access control.

Home

Smart home

In the morning, Sentry I opens the family's garage door. The phone in your pocket is the only key you need — every entry generates a single-use cryptographic key with end-to-end encryption. Every family member has their own access, and you have full visibility of who came in and when.
