AI Acoustic Perimeter Defense

Every threat
has a sound.

श​तघ्नी · Shatagni — the "hundred-slayer," an ancient guardian of the frontier.

Shatagni blankets your perimeter with invisible, solar-powered acoustic nodes. Our edge AI recognises intrusion sounds — gunshots, chainsaws, engines, footsteps — and triangulates the exact location in seconds. No cloud. No internet. Total awareness.

// Process

From sound to response in six steps

A single event travels from a leaf-level microphone to a guard's phone without ever touching the internet. Everything runs on your private network.

01
🎙️
Always Listening
An ultra-low-power co-processor watches the MEMS microphone around the clock at a few milliamps, waking the node only when sound rises above the ambient floor.
02
🧠
Edge AI Classification
On a spike, the node runs its on-board model to classify the sound — chainsaw, gunshot, engine, footsteps — in under two seconds, entirely on the device.
03
📡
LoRa Transmission
A compact event packet — node ID, sound class, confidence, GPS coordinates, and a microsecond timestamp — travels over long-range LoRa radio to the gateway.
04
📍
Triangulation
When three or more nodes hear the same event, the server solves for the source using Time Difference of Arrival — accurate to within five to ten metres.
05
🗺️
Live Dashboard
A real-time perimeter map shows every node's status, alert pins with confidence radii, classification labels, and detection heatmaps at a glance.
06
🚨
Instant Alert
Dashboard, mobile push, SMS, and an optional siren fire together. Guards are dispatched with exact coordinates within seconds of the first detection.

// Capabilities

Everything the perimeter needs

🔇
Invisible Nodes
Bark-matched wraps, concealed antennas, and compact IP67 enclosures make nodes undetectable on tree trunks from ten metres away.
☀️
Solar-Sustained
A small monocrystalline panel and LiFePO4 cell deliver indefinite runtime — no battery swaps, rated through the monsoon.
🏠
Zero Cloud Dependency
The whole system runs on your private network. No internet required, no data leaves your estate — full sovereignty over your security.
📱
Guard Mobile App
A progressive web app works offline on guard tablets — push alerts, patrol zones, and one-tap acknowledge with a GPS stamp.
🌡️
Extreme Weather Ready
Rated −20°C to +60°C and IP67 sealed. Sun shields and thermal pads shrug off Indian summer peaks above 45°C without degrading.
📊
Analytics Dashboard
Detection trends, zone heatmaps, false-positive tracking, node health, and guard response times — all in one live view.
