VERTICAL-02 / BORDER SECURITY
Border tunnel interdiction: detect before they surface.
Smuggling tunnels at border corridors are constructed to avoid surface detection. The detection window is narrow: either during active excavation, or during transit of the completed tunnel. Persistent sensor mesh coverage of high-probability corridors closes that window.
SCENARIO-01 / CONSTRUCTION PATTERNS
What the data says about border tunnel construction.
Based on open-source reporting from US law enforcement and CBP press releases: border smuggling tunnels range from shallow hand-dug passages (1–3m depth, short section, simple cross-section) to sophisticated reinforced tunnels with concrete lining, rail systems, ventilation, and electrical power at 5–30m depth.
Sophisticated tunnels take months to complete and are the harder detection target during construction — but they are used repeatedly and are detectable during active transit. The acoustic and seismic signature of rail carts, ventilation blowers, and walking personnel is distinctive and classifiable.
Shallow, quickly-dug tunnels are detectable during construction via their seismic excavation signature. The detection window is short — often days — which drives the requirement for persistent sensor coverage rather than periodic inspection.
FIT-02 / SYSTEM MATCH
System fit for border corridor deployment.
-
Persistent coverage without on-site personnel
72-hour battery cycle with battery-swap protocol keeps corridors covered without continuous human presence. Mesh topology self-heals if a node goes offline — coverage degrades gracefully, not catastrophically.
-
Remote terrain and harsh environment operation
Operating temperature range -20°C to +55°C covers desert day/night extremes and northern cold environments. Ground-stake deployment variant works in open terrain without infrastructure. No external power or data connectivity required.
-
Temporal pattern analysis over extended periods
The C2 event log captures all classified events with timestamps. Over days and weeks of deployment, activity patterns emerge: scheduled transit times, usage frequency, direction changes. This temporal dimension supplements the real-time alert function.
-
Construction-phase detection via seismic signature
Active tunnel excavation produces distinctive machinery and impact vibration patterns classifiable by the seismic array. For shallow tunnels (under 10m depth) in standard substrates, construction-phase detection from surface-emplaced nodes is achievable.
