5. Operating Suggestions
5.1. Personal computer setting
Do not set your computer to enter ???System standby??? or ???System hibernates??? mode when
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
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???.
