detection will be reduced.
The symbol is displayed constantly on the screen
after the learning phase.
The LED [9] is extinguished for a short time and
the symbol on the screen lights green when
motion is detected. A still image is stored in JPG
format. A maximum of 1 still image per second can be
recorded for constant motion detection.
The LED [9] flashes and the symbol “ REC” is
displayed for approx. 10 seconds at the top left of the
screen when motion is detected. A video sequence (5
frames per second) is stored in AVI format during this
time.
Observe the following points in order to avoid too
many unwanted recordings:
- Do not point the camera directly towards the sun,
other light sources or light reflecting surfaces.
- Do not point the camera at constantly moving
objects.
- Do not point the camera at areas where the shade
changes.
Consider during placement of the camera, that image
changes in light areas are detected by the software
better than image changes in dark areas.
Note that no movement will be detected in a “grey-in-
grey” picture during darkness as the integrated
software has to recognise a change in the image
contrast in order to initiate a recording. The infrared
illumination of the camera is reflected by light surfaces
(for example, light coloured clothing or people's faces)
and provides sufficient contrast. In order to be able to
record images at night, ensure that the camera is
positioned close to the surveillance area (maximum
distance 1.5 m) or that additional lighting is installed.
Switch off the recording mode by pressing the “Motion
Detection” [3] button for this; The LED
[9] goes
out. The recording mode cannot be deactivated while
images are being stored.
- Select the still image mode if a detailed image is
desired. The JPG images stored have a higher
resolution than the AVI video sequences.
- Select the distance from the object according to the
desired detail recognition.
- Note that fast moving objects appear blurred for the
digital storage.

Switch on the recording mode. Press the “Motion
Detection” [3] button for this; the LED
[9] lights.
After activating the recording mode, the symbol at
the top left of the screen flashes for approx. 75
seconds. During this time, the image is “learnt” by the
internal software (= learning phase). The software
adapts itself to constant image changes in order to not
repeatedly by record the same movements. The
image learning is performed every time the recording
mode is activated.
Avoid movements in the camera image during the
learning phase otherwise the sensitivity of the motion
