A complete technology platform, not a pile of devices.

The TEK4 approach connects firewall, switching, WiFi, storage, cameras, automation, identity, and dashboards into one documented operating model.

02

Smart Operations

Home Assistant automations, voice control, SSID toggles, secure dashboards, mobile-first controls, and practical routines that match real life.

03

Private Cloud

TrueNAS apps, self-hosted services, NPM reverse proxy, certificates, Authentik SSO, file transfer portals, project apps, and observability.

04

AI Awareness

Frigate NVR, local Ollama models, object recognition, semantic search, camera tuning, and event workflows without sending your home to the cloud.
