General comparison of the search modes
If one compares the two search modes, it becomes clear that more
search results (hits) result during an intersection search than during
a balance point search.
However, there is a danger at a balance point search that too few
search results are available and that a relevant event is not listed.
If you cannot define the search range (marking) exactly at first,
you should first activate the intersection search mode. After a rough
analysis you can set your marking again and specify a narrower
selection with the balance point search.
6.6 Use database
In the Camera settings dialog (see documentation entitled „Instal-
lation and configuration“) you can decide whether the recording
should be made using the database (DB).
If the track is activated with database recording for playback and
search, the DB will generally be active. One exception to this rule
is if a track has at least one permanently recording camera.

Use DB Do not use DB
Whether it is beneficial to use the database for the search or
playback depends on a large number of factors. In the majority of
cases the DB is activated or deactivated by the software. However,
this can sometimes be changed by the user.
We recommend that you use the software setting for the search
and playback. If the result is unsatisfactory (for example jumpy
playback, long waiting times during the search), you may attempt
to improve performance by switch the DB on or off.
