14.4 Setting HDD Property 
Purpose 
The HDD property can be set to redundancy, read-only, or read/write (R/W). Before setting 
the HDD property, set the storage mode to Group. 
An HDD can be set to read-only to prevent important recorded files from being overwritten 
when the HDD becomes full in overwrite recording mode. 
When the HDD property is set to redundancy, the video can be recorded both onto the 
redundancy HDD and the R/W HDD simultaneously so as to ensure high security and 
reliability of video data.
