5. Operating Suggestions

5.1. Personal computer setting

Do not set your computer to enter “System standby” or “System hibernates” mode when VN-RS800 is in
operation. The operation of VN-RS800 during “System standby” or “System hibernates” mode is not
guaranteed. The “System standby” and “System hibernates” modes can be set under the Power
Options in Control Panel.

5.2. Concerning the CPU load

The frame rate of the image recorded at that time might decrease when processing with a high CPU
load is done with the personal computer VN-RS800's operating. Try to keep the CPU usage about 60 %
or lower by reducing the number of View Windows, setting the frame rate lower or displaying the image
in small size.

5.3. Concerning the recording file save location (hard disk drive) and file save period

It is recommended to use a different disk drive for the recording file save location from the OS system's
drive.
Additionally the NTFS is recommended for the file system of the disk drive which has the file save
location. FAT/FAT32 may sometimes make the recording impossible because of its limitation of the
number of files per a folder.
For the stable performance with recordings over the long term, defragment the disk drive regularly.
Keep the disk drive 70% or less occupied by deleting old recording files using effectively the file save
period setting. This operation also avoids the fragmentation of the disk drive. (See ‘2.2 System Setting
“Recording File Keeping Period” and “Deletion Starting HDD Capacity”)

5.4. Concerning the adjustment of the time of PC

When you return the time of PC at past time, the recorded recording data is overwritten by recording the
data of the same time. Moreover, when you advance the time of PC at time of the future, continuous
image data is recorded as discontinuous recording data.
When adjusting it at time, the recording stop and the recording data are recommended to be backed up
referring to ‘3.2 Terminating (Starting) the Service’ or ‘4 Backup and restoration’.
