overlays the video image in the preview window next to the
parameter settings. With the analysis type, for
example, the sensor fields in which motion is recorded will be
marked with rectangles.
Motion detector ( only)
For the detector to function, the following conditions must be
met:
– Analysis must be activated.
– At least one sensor field must be activated.
– The individual parameters must be configured to suit the
operating environment and the desired responses.
– The sensitivity must be set to a value greater than zero.
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.
NOTICE!
On the Livepage Functions page, you can also enable
additional information overlays for the Livepage (see
Section 12.15 Livepage Functions, page 94 ).
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.
