In terms of education, in recent years, there have been more and more disciplinary and fraudulent behaviors of candidates in various examinations at all levels, and the methods used have become more and more advanced and more subtle. It is difficult to fully take into account and stop it by relying on traditional teacher invigilation alone. The continuous occurrence of this phenomenon has seriously affected the seriousness of the examination and the social credibility of the examination. At the same time, it is difficult for teachers and candidates to obtain evidence when encountering controversial proctoring situations. In order to maintain the normal order of the examination room and ensure the fairness of the examination, it is more and more important to establish a vehicle-mounted wireless invigilation system based on wifi video and voice communication.

The current mainstream monitoring systems are fixed in the center of the ceiling of the classroom, and some blind spots cannot be observed. Some large classrooms cannot observe the overall situation of the classroom through an ordinary fixed monitor.
