Min. object size
You can specify the number of sensor fields that a moving object must cover to
generate an alarm. This setting prevents objects that are too small from triggering
an alarm.
A minimum value of 4 is recommended. This value corresponds to four sensor
fields.
Selecting the area
The areas of the image to be monitored by the motion detector can be selected.
The video image is subdivided into 858 square sensor fields. You can activate or
deactivate each of these fields individually. If you wish 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.
• Click Select area to configure the sensor fields. A new window will open.
• If necessary, click Clear all first to clear the current selection (fields marked
red).
• Left-click the fields to be activated. Activated fields are marked red.
• If necessary, click Select all to select the entire video frame for monitoring.
• Right-click any fields you wish to deactivate.
• Click OK to save the configuration.
• Click the close button (X) in the window title bar to close the window without
saving the changes.
Tamper detection
You can reveal the tampering of cameras and video cables by means of various
options. Run a series of tests at different times of the day and night to ensure that
the video sensor is operating as intended.
Note
The options for tamper detection can only be set for fixed cameras. Dome
cameras or other motorized cameras cannot be protected in this manner as
the movement of the camera itself causes changes in the video image that
are too great.
