Note: Using video motion detection on both image sensors may reduce the
maximum frame rate.
• Video Motion Night Mode: When illumination falls below a certain level, the
camera's image sensor amplifies the remaining light, which in turn produces
image (dark) noise. This noise produces unforeseeable changes in pixel
brightness and results in malfunctioning video motion detection. Use this
parameter to automatically deactivate video motion detection if the illumina-
tion falls below a certain level.
Caution: Use this parameter with due care. Video motion detection will be
deactivated
completely if illumination is too low. Set this parameter to
Off
if
you would like to prevent this from happening.
• Video motion window parameters: The individual parameters of the video
motion windows allow adapting the windows to differing task requirements.
The Video Motion Definitions (VM) field contains the corresponding defini-
tions. Copying the contents of this field to other MOBOTIX cameras is an easy
way of transferring these definitions to other cameras.
• Image Sensor: This parameter determines the image sensor on which
this VM window is to be used (0 = right camera sensor, 1 = left camera
sensor).
• x, y: These parameters determine the distance of the VM window from
the left and the bottom border of the camera image.
• Width, Height: These parameters set the width and the height of the VM
window.
• Sensitivity: This parameter controls how much the brightness of every
pixel in the VM window can change before the software considers it a
"changed pixel". The smaller the value, the higher the sensitivity, as
smaller changes in brightness will include the pixel in the count.
If this parameter has a very small value (e.g.
2
), even the smallest of
change in a video motion window will prompt an event, which in turn
may lead to a higher rate of false alarms.
Note: Change this parameter only if you have set the size of the video
motion window and the
area
parameter accordingly.
