your phone is the access system

Nexus replaces controllers, cards, LAN cabling and on-site servers with a biometric-secured smartphone and a cloud that never stops watching. No infrastructure to install. No hardware to outgrow.

the smartphone

    • Permissions cryptographically locked to your phone's hardware, always in sync - they can't be copied, shared or stolen

    • Secured by the biometrics you already use (Face ID, fingerprint, PIN)

    • Just present your phone - no app to open, no door to select

More than a credential, it's the key, the commissioning tool and the network. Every phone carries its own encrypted, hardware-locked permissions, so the system grows one phone at a time: no controllers to buy, no infrastructure to outgrow.

the cloud

    • Phones and LiveLinks operate independently of the cloud

    • Events received in real time via multiple communication paths

    • Geographically redundant infrastructure - no single point of failure in the cloud

    • Hosted on Google Cloud Platform

The Nexus Cloud manages permissions, credential delivery, diagnostics, reporting and integrations - with no constant reliance on connectivity.

security in front of the door, not behind it

    • No secrets stored at the door - nothing on-site worth attacking

    • Credentials are non-transferable: useless off the phone they were issued to

    • Every exchange happens over a freshly encrypted channel - recorded transactions are worthless

    • System-wide revocation, no revocation lists to distribute

Every permission is signed in the Nexus Cloud, locked to one phone's hardware, and refreshed continuously in the background. Permissions are time-limited by design - access keeps working through outages, and stale credentials simply expire.

Bi directional, zero missed events

    • Mobile phones and site Wi-Fi act as gateways, allowing any node to reach Nexus Cloud through whichever path is available.

    • Every LiveLink can relay through the mesh, so communication is never tied to a single door or connection path.

    • Paths change automatically as connectivity changes, keeping events moving without relying on a fixed network connection.

    • Events are retained until they can be delivered, so a temporary loss of connectivity doesn’t become a lost event

It is called Swarm Intelligence: credentials travel down; events travel up - through whichever path is available at the time.

the nexus mesh network

    • Protocol layer: 2.4GHz mesh Wi-Fi for the network backbone.

    • Self-forming: Devices automatically join the mesh when enrolled via Bluetooth using the Nexus app, no manual network configuration required.

    • Resilient: With no single point of failure, the mesh automatically reroutes traffic if a device or connection is lost.

    • What it carries: Alarms, system upgrades, and buffered events that didn't transmit via smartphones

Every Nexus LiveLink and Nexus device communicates over a 2.4GHz peer-to-peer mesh, connecting to nearby devices instead of a central controller. The network expands node-by-node with virtually unlimited scalability and no home-run cabling.

cryptography

    • AES-256 symmetric cryptography protects the LiveLink protocol, its long-term security does not depend on RSA or elliptic-curve cryptography.

    • Every LiveLink has its own cryptographic keys - keys are isolated to just one door, with separate keys for app communications, Permissions and activity records.

    • Keys are bound to the phone’s secure hardware, device-specific cryptographic material cannot be exported, and copying the app to another phone produces nothing usable.

    • Every door conversation creates fresh encryption keys - no two transactions share the same keys, so a recorded exchange cannot be replayed.

Access decisions happen locally and securely - a zero-trust approach that verifies every transaction at the door, even without an internet connection.

future-ready by design

Fully mobile and cloud-native, Nexus leverages the R&D budgets of Google and Apple - instant access to current and future device features like biometrics, location services and video, with no legacy hardware holding development back.
