This study presents a novel classroom surveillance system that integrates multiple modalities, including drowsiness, tracking of mobile phone usage, and face recognition,to assess student attentiveness with enhanced precision.The system leverages the YOLOv8 model to detect both mobile phone and sleep usage,(Ghatge et al., 2024) while facial recognition is achieved through LResNet Occ FC body tracking using YOLO and MTCNN.(Durai et al., 2024) These models work in synergy to provide comprehensive, real-time monitoring, offering insights into student engagement and behavior.(S et al., 2023) The framework is trained on specialized datasets, such as the RMFD dataset for face recognition and a Roboflow dataset for mobile phone detection. The extensive evaluation of the system shows promising results. Sleep detection achieves 97. 42% mAP@50, face recognition achieves 86. 45% validation accuracy and mobile phone detection reach 85. 89% mAP@50. The system is implemented within a core PHP web application and utilizes ESP32-CAM hardware for seamless data capture.(Neto et al., 2024) This integrated approach not only enhances classroom monitoring, but also ensures automatic attendance recording via face recognition as students remain seated in the classroom, offering scalability for diverse educational environments.(Banada,2025)

What did it mean when the teacher said, "But first I'm going to take the attendance"? For a student, this sentence could mean many things. More time to talk to friends, a chance to "fix-up" yesterday's homework or simply just a time to get settled into class. Every day, the routine is the same. The teacher calls out each student's name, checks the box beside the names of the absent students, sends the completed attendance to the school office and then proceeds with the lesson.

"Sound does not travel in a vaccum." The above concept might just be a simple fact for you – but I had a tough time learning this in the manner it was taught in one of my classes. I actually learnt it when this was implemented in a comic and one of the Super Heroes I followed used this to solve an otherwise difficult challenge. I have been in awe with the power of comics to help us understand concepts in a simple and visual manner. The ebb and flow of stories, the build up and the climax usually hold up people like me for hours.
