When running S.M.A.R.T., the performance of the system will be slightly affected. The higher the check
frequency, the more the sequential access is influenced. It is recommended to turn off S.M.A.R.T. if high
frequency is needed. On the other hand, running S.M.A.R.T. constantly allows you to monitor the
conditions of hard disks at any time.
Different hard disk models and brands will have different attributes in the reporting of S.M.A.R.T. Event
message will show all messages generated by the hard disk.
Beeper – If the Beeper option is enabled, the system will sound an audible alarm in the event of an error.

turn off the alarm.
1. Uncheck the Beeper option.
2. Press the “Mute” button on the front panel.
Equalization Mode – Regardless the transmission method, the data transmission speed can not be

equalization to prevent video frame drops.
