ARM Electronics CMS - Manual (Page 37)

User’s Manual
36
The number of selectable folders equals to the number of HDDs the PC
connects to, excluding HDDs with capacity less than 2GB. Check the
“Enable” box and click <Browse> to set more destination folders. Each folder
should be from different HDD or an error message will be displayed. Note that
if a HDD with less than 2GB capacity is selected, an error message will be
shown. Click on <Clear All> will delete all folders except the first preset folder.
In each folder, subfolders will automatically be created with folder name
“RecordFolder********”, which ******** represents an 8-digit serial number.
Each subfolder can store up to 500 videos. Once a subfolder is full, a new
subfolder with a subsequent number will be created and new files will be
stored to the new subfolder.
Circular Function
The <Circular> function is used to adjust the HDD space usage of CMS. For
example, when the threshold is set to 2GB, and there are 20GB free disk
space remaining in the HDD, CMS can only access the HDD no more than
18GB. When the free disk size is smaller than threshold:
1. If the circulation of files is performed at first time, CMS will start to
overwrite the earliest recoded data. Next time when CMS starts up, the
circulation of files will continue from where it was up to.
2. If the destination folders are reset, new folders will be created to store
new files. The old files will be deleted and rewritten with new files.
