For example, if an alarm triggers recording at 10:00, if the pre-record time is 5 seconds, the camera starts recording at 9:59:55. • Post-record: The time to record after the event or scheduled time. For example, if an alarm recording ends at 11:00, if the post-record time is 5 seconds, it records until 11:00:05. • Expired Time: The time to keep the record files in the HDDs. Once this time is exceeded, the files will be deleted. The files will be saved permanently if the value is set to "0." The actual retention time for the files should be determined by the HDDs capacity. • Redundant Record: Enabling redundant record means records will be saved in the redundant HDD. • Record Audio: Enable this feature to record the video with sound and disable it to record the video without sound. • Video Stream: Main stream, Sub-stream, and Dual-stream are selectable for recording. Sub-stream records for a longer time in the same storage space. Redundant Record is available only when the HDD mode is Group. A redundant HDD is required for the redundant record function.
