Physical bullying in school environments often occurs spontaneously, making it difficult to monitor continuously using conventional Closed-Circuit Television (CCTV) systems. This study aims to implement SAFEYE-AI, a YOLOv11-based bullying detection system integrated with school CCTV, a Flask-based monitoring dashboard, and Telegram notifications. The research employs the AI Project Cycle framework, encompassing problem scoping, data acquisition, data exploration, modeling, evaluation, and deployment. The YOLOv11n model was trained using 3,771 images from school CCTV footage across 10 classes, comprising nine types of physical bullying actions and a student class. Training was conducted over 100 epochs using an NVIDIA RTX 4060 GPU. Evaluation results yielded a precision of 0.903, recall of 0.953, mAP@0.5 of 0.954, and mAP@0.5:0.95 of 0.686. Confidence threshold analysis identified an optimal value of 0.25, resulting in an F1-score of 0.929. Implementation on the CCTV infrastructure demonstrated the system's capability to process up to nine camera streams simultaneously. The system successfully detected kicking and fighting incidents within the school environment and transmitted incident information via Telegram. These results indicate that the integration of YOLOv11, a Flask dashboard, CCTV, and Telegram creates a bullying monitoring system that supports real-time detection and alerting in school environments.
