TECHAY engineers passive sensor architectures that listen through the ground. Every kinetic event leaves a signature — we catch it.
We develop the entire value chain in Türkiye — from PCB to machine learning. Zero third-party dependency, zero backdoor risk, uninterrupted lifecycle support.
TECHAY was founded to deliver scalable, covert and low-cost passive sensor solutions across border security, critical infrastructure protection and tactical intelligence.
Two mission profiles, one core: TUYUQ-SEUS for a fixed, invisible virtual seismic wall; TUYUQ-TEUS for rapidly deployed tactical early warning.

— SEUSA fixed and invisible virtual seismic wall for border lines, pipelines and critical facilities.

— TEUS8–9 kg man-portable; a rapidly deployed tactical early warning system, buried or surface-laid.
Micro-seismic wave capture, frequency-domain transforms, adaptive noise filtering. Separates dismount, vehicle and digging signatures within seconds.
Ultra-low-power embedded sensor nodes; adaptable sensing with fixed-power and man-portable mission options.
Encrypted data links, wireless mesh network and tablet / command-and-control alerts.
In-house classification models, no third-party libraries. Agile OTA updates driven by field telemetry.
Thermal/optical (EO/IR) payload integration, Slew-To-Cue architecture. Cooperative coordination for positive visual ID.
Event-driven alarm protocols, map-overlay visualization, smart filtering to reduce operator cognitive load.
