Overview

A Django web application that analyses webcam and uploaded video frame by frame with trained YOLO models, captures anomalies with timestamps and sends automated email alerts, with remote web access.

An applied computer-vision product for monitoring video sources and flagging anomalous events for human review. Detection scope is limited to the classes the model was trained on; this is anomaly detection, not a certified law-enforcement system.

The challenge

  • Keeping frame-by-frame inference responsive on commodity hardware
  • Reducing false positives to a level operators can trust

What we built

  1. Webcam and uploaded-video input paths
  2. Frame-by-frame analysis with trained Ultralytics YOLO models
  3. Anomaly capture with detection timestamps
  4. Automated email notification with captured evidence
  5. Remote web access to review detections
