– Enhanced separation
– Activated: Improves the detection and separation of objects that move in close 
proximity to one another. This option requires additional computing power.
– Deactivated: Objects moving in close proximity to one another may blend into one 
object.
Advantages and disadvantages of the individual setting depend on the captured image.

4.7.3 Sensitive Area
The sensitive area is that part of the image seen by the camera that is analyzed. Objects 
moving outside the sensitive area cannot generate an alarm event even if they are caught by 
the camera.
Only objects moving inside the sensitive area are detected as such and generate an alarm 
event – this also applies for the later evaluation of recordings in the Archive Player program.
The larger the sensitive area, the more computing power is required. Data will be processed 
more slowly.
A smaller sensitive area means that data processing is faster.
In the default setting, the whole of the image captured by the camera is defined as the 
sensitive area. Any areas that consist of small squares can be defined as non-sensitive (or 
again as sensitive). There are four editing tools you can use for this purpose. You can repeat 
this operation as often as you like. You can therefore achieve a very precise definition of the 
sensitive area.
Examples of areas that could be defined as non-sensitive:
– Railroad: 
Passing trains can trigger unwanted motion alarms.
– Public streets:
Passers-by moving across a public space should not be detected – in order to save 
unnecessary computing power and prevent unwanted false alarms.
– Neighboring properties: 
Areas in which moving objects are not anticipated.
–Sky: 
Birds or planes can trigger false alarms.
– Trees or bushes that move in the wind.
The sensitive area is shown in yellow hatching.
