In university dormitories, personal privacy is generally not monitored, but it is monitored in public places such as corridors.

Generally, monitoring will not be watched 24 hours a day, unless it is very important, such as public security monitoring at traffic police intersections. The monitoring of the unit is generally recorded, and the security guards only take a look occasionally. After all, there are so many shots, only when problems are found will history be replayed and queried, and it will be covered in a limited time, such as a week or a month, unless it happens to be seen by security guards.
