AI powerd Security device for insecurity in nigeria # NISHA Sentinel > **Distributed Telemetry & Surveillance System** > > Real-time acoustic and visual threat detection using edge AI, mesh networking, and multi-agent correlation. Architecture • Quick Start • Components • Documentation • License --- ## 🎯 Overview NISHA Sentinel is a production-grade surveillance platform that connects distributed audio/video sensor agents to a central AI backend for real-time threat detection. The system employs: - **Edge Agents**: ESP32 microcontrollers + mobile phones streaming audio/video - **Master Nodes**: Raspberry Pi aggregators with local buffering and failover - **Central Backend**: FastAPI service with YOLOv8+LSTM violence detection - **Dashboard**: Next.js web app with real-time maps, topology graphs, and alerts - **AI Pipeline**: Pose estimation + behavior classification + multi-agent correlation **Key Features:** - ✅ Binary NISHA protocol (24-byte header, priority queues) - ✅ Continuous video streaming + audio capture - ✅ GPS location tracking with background updates - ✅ AI violence detection (78% accuracy, real-time) - ✅ Multi-agent event correlation (spatio-temporal) - ✅ Mesh topology with handoff & failover - ✅ Delta-based configuration management - ✅ WebSocket real-time updates - ✅ Docker Compose deployment --- ## 🏗️ Architecture ``` ┌─────────────┐ ┌─────────────┐ ┌─────────────┐ ┌─────────────┐ │ ESP32 │ │ Mobile │ │ Master │ │ Backend │ │ Agent │────►│ Agent │────►│ Node │────►│ (FastAPI) │ │ (Audio) │ │ (AV+GPS) │ │ (Pi) │ │ │ └─────────────┘ └─────────────┘ └─────────────┘ └─────────────┘ │ ▼ ┌──────────────────┐ │ PostgreSQL │ │ + Redis │ └──────────────────┘ │ ▼ ┌──────────────────┐ │ Next.js │ │ Dashboard │ └──────────────────┘ ``` **Protocol**: NISHA binary frames (TELEMETRY, VIDEO, AUDIO, LOCATION streams with 4 priority levels). **AI Models**: YOLOv8-n …
