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.
