The Problem

The Hidden Energy Drain in Academic Institutions

  • 30–40% Energy Waste — Campuses mein khali rooms mein lights/fans on rehne se har saal lakho rupaye ki electricity waste hoti hai.
  • Human Negligence — Students aur staff jaldi mein switches band karna bhool jaate hain.
  • High Carbon Footprint — Waste electricity seedha CO₂ emissions badhati hai.
Existing Solutions

Why Current Solutions Don't Work

SolutionDrawback
PIR / Motion SensorsFalse trigger when still; costly install.
Fixed TimersRigid schedule, doesn't adapt to class timing.
Manual GuardsInefficient, manpower waste, human error.
Our Edge: Zero new hardware — existing CCTV cameras ka use karke AI detection!
Our Solution — The Game Changer

System Architecture

How It Works (End-to-End Pipeline)

CCTV / Webcam Feed
↓
Computer Vision AI Engine — OpenCV
↓
Occupied → Lights ON, Reset Timer
Empty → Power-Off Relay, Log Savings
↓ JSON sync
Cloudflare Edge Tunnel → Admin Portal
Tech Stack & Security

Technology Stack

  • AI & CV: Python, OpenCV (Haar-Cascade / HOG Detection)
  • Edge: Multi-threaded Python Web Daemon
  • Cloud: Cloudflare Quick Tunneling (QUIC, E2E Encryption)
  • Frontend: HTML5, CSS3 Glassmorphism, Responsive UI
  • Security: Role-Based Access Control (RBAC)
Live Demonstration

Live System Demonstration

Step 1

Person in frame → Light ON, Count: 1.

Step 2

Person leaves → 10s countdown starts.

Step 3

Timer ends → Light OFF, savings tick live.
