AntiHunter DIGI Node PCB
Distributed Perimeter Defense & Wireless Threat Monitoring
What is it?
The 2.4GHz DIGI Node PCB for AntiHunter (an open-source distributed perimeter defense platform).
One node works standalone with its own WiFi AP or headless over LoRa mesh. Three or more nodes unlock distributed trilateration and coordinated perimeter coverage over kilometers. Connect to the open-source AntiHunter Command Center for live maps, geofencing, drone tracking, and multi-site federation.
No subscriptions. No cloud dependency. No recurring fees.

Who is this for?
You want to know what wireless devices are moving through your space -- without paying someone a monthly fee for the privilege.
Know who's around before they knock. Learns which devices belong, alerts when new ones appear or familiar ones vanish. A wireless trail camera that sees through walls and tree lines.
Catch drones before they catch you. Detects FAA Remote ID broadcasts with pilot location and flight telemetry. Mesh-wide alerts the instant a drone enters your airspace.
See through the tricks. Phones randomize their MAC to hide. AntiHunter fingerprints behavior across address changes and assigns a persistent identity no matter how often it rotates.
Hunt the hunters. Catches deauth attacks, network probes, and client jamming -- then cross-references with the fingerprinting engine to identify who's behind it.
Cover ground without infrastructure. LoRa mesh links nodes over kilometers with no WiFi, cellular, or internet. Three nodes triangulate a target's position. Runs headless and invisible, or feeds a full C2 with live maps and TAK integration.
Protect what you've collected. Tamper sensor triggers secure data destruction before anyone pulls the SD card. Remote authenticated wipe across the mesh. Post-wipe, the device masquerades as a weather station.
What does it do?
AntiHunter turns off-the-shelf modules into autonomous wireless security sensors that coordinate over long-range LoRa mesh. Nodes operate standalone via built-in WiFi AP, fully headless with zero wireless footprint over mesh, or connected to the open-source AntiHunter Command Center C2 platform.
Node firmware
- WiFi + BLE device scanning with target watchlists (MAC and OUI prefix) and configurable RF presets
- Baseline anomaly detection -- learns your RF environment, alerts on new/disappeared/changed devices, up to 100K tracked on SD
- MAC randomization correlation -- tracks devices across address changes via behavioral fingerprinting, persistent across reboots
- Drone Remote ID detection (FAA ASTM F3411 + French format) with pilot location, flight telemetry, and immediate mesh alerts
- Deauth attack sniffer integrated with the randomization tracker for source identification
- Probe scan identifies networks that devices are calling out for
- Data explorer to review and export findings from SD card
- Multi-node RSSI trilateration with Kalman filtering across 3+ nodes, GPS-weighted, with confidence scoring
- Tamper-triggered secure data destruction with configurable auto-erase, remote authenticated mesh wipe, and post-wipe device obfuscation
- Every mode controllable over LoRa mesh -- broadcast or per-node targeted commands
Command Center
- Live map with node tracking, device trails, geofence polygons, and drone flight paths
- Drone tracker with FAA registry lookup, pilot pins, and Friendly/Neutral/Hostile classification
- Geofence breach alarms, custom alert rules, scan scheduling
- MQTT multi-site federation and TAK/CoT integration (ATAK/WinTAK)
- RBAC, 2FA, webhook engine, full audit trail, CSV/GeoJSON export
How AntiHunter compares
Nothing else combines WiFi/BLE scanning, drone detection, MAC randomization correlation, LoRa mesh, device trilateration, tamper security, and an open-source C2 in a single battery-powered node. The closest commercial systems cost $5K-$250K+ per sensor and each only cover a subset of these capabilities.
