FIG · 01 — Silent Dome system block. Cyan = sensor uplinks · gold = decision / output · red dashed = restricted / gated. Reference part names are indicative reference designs, not committed BOM.

▲ Decision loop

Detection to alert in ~3 seconds.

T+0.0s
Detect

Acoustic / RF / Radar layer trips threshold.

T+0.3s
Track

Bayesian fusion correlates sensor streams.

T+1.1s
Identify

Protocol fingerprint · operator triangulation.

T+2.4s
Classify

Optical PTZ slews, locks, scores threat.

T+3.0s
Alert

Push to operator UI, log, optional escalate.

▲ Reference parts

Built on qualified COTS — not custom silicon.

Every layer of Silent Dome uses commercially available, field-proven components. This keeps unit cost predictable, supply chain resilient, and lets us ship without waiting on bespoke hardware.

Block
Role
L1 · Acoustic Array
Close-range rotor-signature detection
MEMS 4-mic beamform array · STM32 / Cortex-M edge MCU
L2 · RF Drone Intel
Passive protocol fingerprint + operator triangulation
Wideband SDR front-end (400 MHz – 6 GHz) · NN protocol classifier
L3 · Compact Radar
All-weather micro-Doppler tracking
Custom 77 GHz mmWave radar module · automotive-silicon-derived (Arbe / Uhnder class) with C-UAS-tuned waveform and AI micro-Doppler classifier. Not equivalent to dedicated C-UAS radars from Echodyne or Robin, which list materially higher.
L4 · EO/IR PTZ
Cued forensic confirmation + evidence imagery
30× daylight zoom PTZ (class: Bosch MIC, Hanwha PNP) · optional uncooled LWIR thermal upsell (FLIR Boson class) on Estate+ SKU and above
CORE · AI Fusion
Inference, fusion, classification, policy
Embedded NPU module · ≥20 TOPS sparse INT8 (Hailo-8 class) up to ~100 TOPS (NVIDIA Jetson Orin NX 16GB high-tier) per SKU · fusion forward-pass <120 ms · NDAA §889-compliant
O1 · Operator UI
Live map, alerts, multi-device console
WebRTC console · iOS / Android push · SMS / email gateway
O2 · Evidence Log
Signed chain-of-custody for forensic / legal use
Signed JSON + MP4 · SHA-256 · S3-compatible cold storage
O3 · External API
Integration into existing security stack
MQTT / REST · OAuth2 + mTLS · Genetec, Milestone, Splunk connectors
O4 · Response Layer
Optional — gated to authorized operators only · not part of civilian or commercial deployments
Authorized-operator effector partner integration · US gov / defense / SLTT only · multi-factor fusion lock + geofenced engagement zone + full audit log

Brand names above are reference candidates illustrating the class of component used. Silent Dome qualifies and selects parts per deployment; final BOM may vary based on availability, regulatory zone, and customer requirements.
