New Functions and Improvements
The administrator account now accepts "root" as a valid username as well.
AXIS Camera Station integration has been significantly improved:
The ACS tab in the web interface is now renamed to AXIS.
AXIS Camera Station integration is now always enabled and accessible using the device's administrator account.
After the initial login to the web interface, the "root" username can also be used for ACS access.
An optional dedicated ACS account is now available.
If ACS was previously enabled with both username and password configured, the dedicated account can still be used.
If your dedicated ACS account used "admin" or "root" as the username and had the same password as the administrator account, it will be merged with the administrator account and you can continue using the same credentials.
If your dedicated ACS account used "admin" or "root" but had a different password from the administrator account, it will be migrated to a temporary administrator account. You can continue using the same credentials, and the account will be merged with the administrator account after its password is updated.
2N IP Utility can now also be used to configure IP settings after the default password has been changed.
Lift products can now dial up to 6 destinations per user, increased from the previous limit of 3.
