It is not illegal for teachers to install monitoring in classrooms. The classroom is a school management place, not a private space, and there is no problem that installing a camera will invade privacy. According to relevant regulations, natural persons have the right to privacy. No organization or individual may infringe upon the privacy rights of others by spying, harassing, exposing or making public. Privacy refers to a kind of personality right that citizens enjoy the peace of private life, and private information is protected according to law, and is not illegally harassed, informed, collected, used and made public by others.

You can take the teacher qualification certificate if you have an illegal record:

This depends on the specific circumstances of the crime. If it is a negligent crime, it will have no effect.

1. Those who have been deprived of political rights or have received criminal punishment of more than fixed-term imprisonment for intentional crimes cannot obtain the qualification of teachers.

2. Those who have obtained the teacher qualification will lose their teacher qualification.

If a teacher loses his qualification, the education administrative department at or above the county level where his work unit or household registration is located shall go through the cancellation procedures with the original issuing authority, collect the certificate and put it on record. Those who lose their teacher qualifications cannot regain their teacher qualifications.
