5. Enter user name and password.

   User Name

   The user name for administrator account created when activating the device or the added non-admin account such as operator. When adding the device to HikCentral Professional using the non-admin account, your permissions may restrict your access to certain features.

   Password

   The password required to access the account.

   CAUTION:

   The password strength of the device can be automatically checked. We highly recommend you change the password of your own choosing (using a minimum of 8 characters, including at least three kinds of following categories: upper case letters, lower case letters, numbers, and special characters) in order to increase the security of your product. And we recommend you change your password regularly, especially in the high security system, changing the password monthly or weekly can better protect your product.

   Proper configuration of all passwords and other security settings is the responsibility of the installer and/or end-user.
