The campus anti-bullying system supports long-distance audio pickup and automatically triggers an alarm and recording upon detecting specific keyword speech, with both audible and visual alerts. Each action of the pickup device (such as keyword detection or recording) is automatically stored for future review. When connected to an external smoke detector, it can also function as a fire alarm system. The system supports distributed mode, enabling independent operation without a server, making it suitable for concealed corners or private areas. It provides basic rescue and fire warning functions and can serve as a small-scale emergency broadcasting unit.
