The DVR will generate a 
Time Index Table 
indicating recorded data is kept in a particular 
HDD. This allows the user to individually 
selecting recorded data to be displayed via the 
alarm list search and full list search. The 
maximum number of lists for a given HDD is 
3000
. 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 
3000 in total. And the next oldest data will be 
kept in the index of the corresponding oldest 
data. 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 is being overwritten   
by the recent recording, the indicating time index 
of that data will be changed corresponding to the 
starting time of the remaining session. The index 
of the session will be deleted from the table 
when it is fully overwritten.
