# GuardianAI — AI Violence Detection for Schools

> Detect physical violence on school and campus cameras within 1–2 seconds. Pose-based computer vision. No facial recognition. Privacy-first by design.

## Hero
**Detect School Violence in 1–2 Seconds.** GuardianAI combines pose extraction and spatiotemporal graph models to help schools and campuses detect physical violence fast. Instant alerts. Zero facial recognition. Privacy-first by design.

## How it works (camera to alert, under two seconds)

### 1. Connect
Any RTSP IP camera, USB webcam, or video file. One click to start real-time monitoring.

### 2. Analyze
Stage 1: YOLO11n-Pose extracts 17 skeletal keypoints per detected person.
Stage 2: a CTR-GCN spatiotemporal graph classifier scores aggression patterns over a 64-frame (~2 s) window.

### 3. Alert
Instant Telegram notification with a screenshot, camera location, and confidence score. Designated staff confirm or dismiss with one tap, which feeds back into the model for continuous improvement.

## Why pose, not pixels
Most off-the-shelf school-safety AI runs face recognition — illegal in many U.S. states for K-12 use, GDPR Article 9 risk in the EU, and creates a permanent biometric record of every minor on camera. GuardianAI's two-stage pipeline operates on (x, y, confidence) skeleton coordinates only. The classifier is architecturally incapable of identifying any specific person; it only describes motion.
