10. Index Table

The following description details how the DVR manages an index table issue.

The DVR will generate a time index table indicating recorded data kept on a particular HDD. This allows the user to individually select the recorded data to be displayed via the alarm list search and full list search. The maximum number of lis ts for a given HDD is 3,000 . When the list of any given HDD is used up and the disk is not full, the unit will still use the rest of the space for recording. In such a case, an index for the recent recorded data will be generated, and the index of the next oldest data will be erased so that the list does remain 3,000 in total. For any newly-recorded data, this approach will be applied until the disk becomes full.

In the rewrite recording mode, when the archived hard disk drive is full, the DVR will start overwriting the oldest data recorded. As the previous recorded data was partially overwritten by the recent recording, the indicating time index of that data will be changed corresponding to the starting time of the remaining s ession. The index of the session will be deleted from the table when it is fully overwritten.
