Chapter 5
The sensitivity of the video sensor can be adjusted, so an alarm is generated only
if specified values are exceeded.
In order for the sensor to function, the following conditions must be met:
The motion detector must be enabled.
At least one cell must be activated.
The individual parameters must be set for the operating environment and the
desired responses configured accordingly.
The sensitivity must be set to a value greater than zero.
Warning!
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 video sensor and generate false
alarms. Run a series of tests under day and night conditions to ensure that
the sensor works as intended.
For indoor surveillance, ensure constant lighting of the areas during the day
and at night.
Uniform surfaces without contrast can trigger false alarms even with
constant lighting.
– Click one of the tabs to access the configuration of the corresponding
encoders (or camera).
– Click Reset in the Default settings area to revert the settings to their default
values.
– Click the remaining tabs to access and edit the configurations of additional
encoders.

Select On to activate the video sensor.
Sensor fields
The areas of the image to be monitored by the video sensor can be selected. The
video image is subdivided into 192 square sensor fields. Each of these fields can
be activated or deactivated individually. If it is necessary 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.
