Indexes
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.
