Motion detection
The Motion detection function checks whether and how much the contents of two
consecutive pictures are different. If the difference satisfies the set criteria, the function
assumes a Motion event. This motion event can trigger various functions or actions.
NOTE
This dialog can be locked by an external device / application.
Please note the details in the Event log chapter (14.3).
Functions / actions which may be based on the motion detection:
z
Motion recording mode
z
Message to alarm host in the event of Motion detection
z
Motion event recording
z
SmartFinder function
The general configuration of the motion detection refers to all functions / actions.
If SmartFinder is used, some restrictions and additional options must be taken into
consideration (see below).

General configuration
¾
Open the Motion detection dialog via Common settings > Motion detection ....

Please note the explanations
below.

Set the Sensitivity (slider).
¾
Set the Level SAD.
¾
Select the Sensitivity (drop-
down box).

Finally confirm with OK.
The motion detection function splits a picture into various sectors (16x16 pixels). These are
reviewed individually for signs of changes compared to the previous picture (SAD value).
On the basis of the number of unchanged sectors, a decision is then made as to whether
the overall picture is assessed as a motion event (Sensitivity (slider)).
Finally the system checks (Sensitivity (drop-down box)) whether the changed sectors in
the full picture are linked (1 object) or spread (lots of objects). The restriction on the number
of objects prevents lots of minor changes being assessed as an event. This allows incorrect
detections from noisy pictures or snowfall to be reduced.
