6.2 Deactivate/activate installer access
Block user "Installer":
If the "Master" or "Installer" user has forgotten their login information, you must load
the factory settings for the camera via the "RESET" button. This will restore all
usernames and passwords to factory settings.
The "Master" user can block installer access (="Installer" user)
when the installation has finished. Access can be activated
again, if required.
