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 video sensor and generate false
alarms. Run a series of tests at different times of the day and night to en-
sure that the video sensor is operating as intended.
For indoor surveillance, ensure constant lighting of the areas during the
day and at night.
– Click one of the tabs to open the configuration of the corresponding encoder
or camera.
– Enter the desired settings.
– If necessary, click the Default button to return all settings to their default values.
Detector:
Select On to activate the video sensor. The current video standard and the cur-
rent alarm state are displayed.
Sensitivity
The basic sensitivity of the video sensor 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.
Min. object size
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.
