According to the detailed rules for the implementation of safety precautions for kindergartens in primary and secondary schools in Zhejiang Province, monitoring equipment must be installed in public parts of kindergartens to ensure that children can have evidence when accidents occur, but it is not stipulated that classrooms should also be installed. Kindergarten installation monitoring is mainly to standardize management, such as food safety in kindergartens.
The monitoring image data formed by monitoring facilities shall be kept for at least 30 days for future reference, and shall not be deleted or diffused. This means that schools can't publicly monitor videos at will. Parents of students should submit a written application to the kindergarten to watch the video, but they are not allowed to watch it at will, and the kindergarten will submit it to the competent department and the public security organ for approval.
