Hear Threats. Protect Access. Offline.

Cloud-standard security features —
now running fully offline on microcontrollers.
  SoundGuard — IP block (critical sound detection)
  • Detects gunshots, screams, crashes, alarms, glass break.
  • Tunable for different environments, noise levels, and device acoustics.
VoicePIN — IP block (offline numeric PIN)
  • Recognizes spoken numeric PINs fully offline.
  • Configurable phrase set and PIN length; robust in noisy conditions.

Customization Options

  • Add new sound classes (industrial alarms, tamper events, sirens).
  • Adjust thresholds to balance false alarms vs. recall.
  • Adapt VoicePIN to different languages and grammars.
  • Optimize for latency, accuracy, and energy on your platform.

Platforms We Support

  • ESP32 (incl. ESP32-S3) → fast PoC and cost-sensitive devices.
  • Arm® Cortex™-M + Arm® Ethos™-U55 / other AI SoCs → optimized for performance and ultra-low power.
  • Migration path: start on ESP32 → battery-powered reference module.

Applications

Smart City & Infrastructure

detect critical events like gunshots, alarms, or crashes in real time

Industrial Safety

monitor shop floors for incidents, alarms, and accidents

Access Control

enable offline numeric PIN as a frictionless factor for gates, doors, or devices

OEM Benefits

  • Lower OPEX — fewer false alarms, fewer manual interventions, lower service costs.
  • Safer environments — prevent incidents, reduce risks and liabilities.
  • Minimal BOM impact — add offline safety and access with negligible cost.
  • Compliance simplified — privacy-first, offline design passes legal and regulatory checks.
  • Pro SKU differentiation — security features create premium product lines.

How We Work

Evaluate
Pilot (PoC)
License & Integrate
  1. Evaluate — define target sounds, access scenarios, hardware.
  2. PoC — 2–3 weeks, fixed scope, measurable results.
  3. License & Integrate — adapt IP for production; PoC fee credited.

Deliverables

  • SoundGuard and VoicePIN IP binaries + config tools.
  • APIs and headers for integration.
  • Test datasets and profiler traces.
  • Metrics pack (latency, accuracy, false alarms, energy).
  • Demo video on your board.

Licensing

  • PoC license — quick validation.
  • Project license — tuned models + integration support.
  •  Volume license — mass deployment, flexible terms.
No lock-in: portable IP, stable APIs, OEM retains integration code.
