I have previously addressed this issue regarding Surveillance and it was confirmed.
Probably the applications are launched by the main user and the folders created by the application have full access rights for him.
For other users, limited rights are issued that do not correspond to the settings of the parent folder and the rights set for this user.

Surveillance:
New folders with the name of the day, where Surveillance records are stored, created automatically, are created with the rights to deny access for the user from whom they are shared for MacBook. Although this user has rights to the root folder.
You have to set permissions for automatically created folders manually.
