In Figure 4-169, when it is USB mode, after you imported, you need to connect the USB device all
the time; otherwise, the audio link function may fail. So, if you want to use the audio trigger function,
please make sure the audio file is on the UBS device and the USB device has connected to the
DVR before the DVR boots up. You need to make sure the USB device connection is always there if
you want to manage and use the audio file function.

If there is a USB device (containing the audio file) and the HDD (containing the audio file) at the
same time, the HDD mode has higher priority. That is to say, DVR uses the audio file from the HDD.

includes the valid character, letter, number, underline, subtraction sign, and dot.

The default user amount is 64 and the default group amount is 20. System account adopts two-level
management: group and user. No limit to group or user amount.

For group or user management, there are two levels: admin and user.

The user name and group name can consist of eight bytes. One name can only be used once.
There are three default users: admin/888888 and hidden user
“default”.

Hidden user
“default” is for system interior use only and can not be deleted. When there is no login
user, hidden user
“default” automatically login. You can set some rights such as monitor for this
user so that you can view some channel view without login.

One user should belong to one group. User right can not exceed group right.

About reusable function: this function allows multiple users use the same account to login.

About user account and MAC. When you add a new user, you can input the MAC address of current
user. Only the user of the same MAC address can access the device remotely.(MAC address is for
the device of the same LAN.) If you leave MAC address item in blank when you add a new user, the
user of any MAC address can access the device remotely. You can set or change MAC address
when you add or modify a user. The MAC address function is also valid for PSS login. Please note
current function does not support IPV6.
After all the setups please click save button, system goes back to the previous menu.
