The camera installed in the school is used to equip the standardized examination room for large-scale national examinations and to temporarily replace teachers and monitor the classroom for self-study time. The property lost by students in the classroom can also be found in reverse.

The processing, use and storage of school video content must be confined to the campus, because the public boundary of the classroom is established and confirmed on the basis that the school has the right to manage students. However, the video of the classroom is circulated on the network for no reason or intentionally, which has nothing to do with the necessary management of the school and is beyond the scope of the campus. It is suspected of infringing students' privacy by spreading surveillance video data to a broad cloud platform.
