Sensitivity ( only)
The basic sensitivity of the motion detector can be adjusted for
the environmental conditions to which the camera is subject.
The sensor reacts to variations in the brightness of the video
image. The darker the observation area, the higher the value
that must be selected.
Minimum object size ( only)
You can specify the number of sensor fields that a moving
object must cover to generate an alarm. This is to prevent
objects that are too small from triggering an alarm.
A minimum value of 4 is recommended. This value corresponds
to four sensor fields.
Debounce time 1 s ( only)
Select this checkbox to prevent very brief alarm events from
triggering individual alarms. If the Debounce time 1 s option is
activated, an alarm event must last at least 1 second to trigger
an alarm.
Select Area ( only)
The areas of the image to be monitored by the motion detector
can be selected. The video image is subdivided into 858 square
fields. Each of these fields can be activated or deactivated
individually. If you want to exclude particular regions of the
camera's field of view from monitoring due to continuous
movement (by a tree in the wind, etc.), the relevant fields can
be deactivated.
1. Click Select Area to configure the sensor fields. A new
window will open.
CAUTION!
Reflections of light (off glass surfaces, etc.), switching lights on
or off or changes in the light level caused by cloud movement
on a sunny day can trigger unintended responses from the
motion detector and generate false alarms. Run a series of tests
at different times of the day and night to ensure that the video
sensor is operating as intended.
For indoor surveillance, ensure constant lighting of the areas
during the day and at night.
