Motion
The
Motion
recording mode analyzes every image send by the camera. If a change of a
certain proportion of the picture content is detected between two consecutive images, an
image comparison event (event) has taken place. This picture comparison event triggers
the recording.
Recording will be stopped when the
Post-Event time
is expired and no further motion is
detected.

Sensitivity
The more sensitive the image comparison is, the less the proportion of the picture contents
must change to trigger an image comparison event.
Pre-Event time
This option enables you to set a period during which the latest images from the camera are
retained in a buffer. If an event occurs these images are saved together with the recording
in the track. This allows the situation prior to the event to the evaluated.
Post-Event time
The
Post-Event time
specifies how long a picture comparison event is valid. Whilst it is
valid all subsequent picture comparison events will be assigned to it without triggering a
new event. The
Post-Event time
is used to prevent an excessive number of events.
