By default, the software records to all hard drives in the system—except for the system drive. On the Disk tab, each disk
drive is represented by a blue bar, which indicates how much of the disk is full. The system saves a one-minute
segment of data to the first available drive, then the next, then the next, and then back to the first drive after all disks
have received a segment of data.
You can choose which disk drives the system saves data to by selecting or deselecting any drive from the Enable Drive
box. Only selected drives are indicated in the bar graph.
The system runs in circular record mode, in which it saves video to disks up to a capacity specified by the user, and
then it begins writing over the oldest video on the disk. To adjust how much of the disks can be filled before old
video is eliminated, adjust the Disk Threshold slider bar on the Disk tab.
The section below the bar chart, as shown in the preceding screen capture, indicates how much of the enabled disk
space is full. In this sample, three drives are selected.
Purging Captured Video
You can also use the Disk tab to purge captured video. At the bottom of the Disk tab are two drop-down calendars.
Enter starting and stopping dates. All video captured on or between these dates will be deleted. Then, click the Purge
button. You can also purge video from all days by selecting Full Purge before you click the Purge button. You should
see the bar graph change to indicate that a portion of each disk was emptied. Note that purging a large quantity of
files may take a considerable amount of time.
Setup Tab #4: Defining System4 Server Users
User IDs and passwords are required whenever you run the System4 Server software (unless Auto Run is enabled). To
add users or change their permissions, go to the Setup page and click the Users tab.
Following are the four types of user permissions available:
• Administrator has full access to the configuration software.
• Supervisor has full access to the configuration software except for the Users tab on the Setup page.
• User can access only the Monitor, Search, and Help pages. A User also cannot exit the configuration software.
• Disabled has no access to the configuration software.
To create a user, enter the user's ID in the User Name field. Then, enter a password in the Password field and
confirm it in the Confirm Password field. Choose any of the four levels of permissions and click the Add button.
