• The Keep no less than parameter enables keeping the deeper archive on the selected camera by means of archives of other cameras. It is recommended to set the Keep no less than parameter not more than on 30% of cameras in the system as this is advisory setting. If there is not enough space for keeping the archive, then the setting will be ignored and loop recording won’t stop anyway (see General information on video archiving). If not less than 10 cameras are created in the system, then there will be the corresponding warning when clicking the Apply button while attempting to set this parameter for more than 30% of cameras. It can be disabled using the NotifyAbout_arch_days registry key (see Registry keys reference guide).
• The Keep no longer than parameter enables specifying the time period over which the camera archive will be kept and at the expiring of which the archive will be deleted. The archive can be deleted earlier than specified time period if it is required by the loop recording. The check for files to be deleted is performed every 10 minutes system time (every 10 minutes after Intellect starting – since 4.10.5). If the deletion process takes more than 10 minutes, the next check starts in 10 minutes after the end of deletion.
