🔴 Live Detection System
AI-Powered Surveillance
Backend Platform
A full-stack Flask-based surveillance engine delivering real-time weapon detection, persistent alerting, and live MJPEG streaming — built for enterprise security environments.
🔧 Step-by-Step Detection Process
From server boot to alert dispatch — every stage engineered for reliability.
STEP 01
Server Initialization
Flask starts with CORS enabled for frontend integration. Global states are initialized for detection control, frame storage, and alert tracking.
STEP 02
Configuration Loading
System loads default configuration including confidence thresholds, model weights, device type, and alert rules — dynamically updatable via API without restart.
STEP 03
Detection Start API
Calling /api/start spawns a background thread. Video source — webcam, RTSP stream, or file — is passed to the detection engine.
STEP 04
Video Processing Loop
Frames are continuously captured using OpenCV. Each frame passes through the custom tracking-based model for detection, classification, and unique track ID assignment.
STEP 05
Threat Identification
Detected objects matching alert categories undergo persistence validation to eliminate false positives. Once confirmed, an alert event is triggered automatically.
STEP 06
Alert Generation System
Snapshots are saved with full metadata — timestamp, confidence score, track ID, and source. Optional VLM integration generates AI-powered descriptive insights.
STEP 07
Real-Time Streaming
Processed frames are MJPEG-encoded and streamed live. The frontend accesses the annotated detection feed via /api/video_feed.
STEP 08
Data Access APIs
RESTful endpoints serve live detection state, full alert history, and analytics summaries to connected dashboards and monitoring tools.
STEP 09–10
Alert Management & Stop
Alerts persist in JSON storage with full CRUD support. A dedicated stop API safely terminates the background thread and releases all video resources.
Everything you need for production-grade intelligent surveillance.
🎯
Real-Time Object Detection
Multi-class weapon detection with persistent object tracking across consecutive frames.
🔔
Persistent Alert System
Snapshot storage with full metadata — timestamp, confidence, track ID, and video source.
⚡
Multi-Threaded Architecture
Non-blocking performance via background threading; API stays responsive under high load.
📡
Live MJPEG Streaming
Low-latency annotated video feed consumable by any browser or dashboard client.
⚙️
Runtime Configuration
Adjust confidence thresholds, model weights, and alert rules without system restart.
🧠
VLM Integration
Optional vision-language model generates human-readable descriptions of detected threats.
🔌
REST API Integration
Clean JSON API for detections, alerts, and stats — integrates with any frontend or SIEM tool.
