Minimum object size (MOTION+ only)
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.
Debounce time 1 s (MOTION+ only)
The debounce time is intended to prevent very brief alarm events from triggering individual
alarms. If the Debounce time 1 s option is activated, an alarm event must last at least one
second to trigger an alarm.
Select Area (MOTION+ only)
The areas of the image to be monitored by the motion detector can be selected. The video
image is subdivided into 858 square fields. Each of these fields can be activated or
deactivated 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.

Sensitivity
Notice!
This and the following parameter are only accessible if the reference check is activated.
The basic sensitivity of the tamper detection can be adjusted for the environmental conditions
to which the camera is subject.
The algorithm reacts to the differences between the reference image and the current video
image. The darker the observation area, the higher the value that must be selected.
Trigger delay (s)
You can set delayed alarm triggering. The alarm is only triggered after a set time interval in
seconds has elapsed and then only if the triggering condition still exists. If the original
condition has been restored before this time interval elapses, the alarm is not triggered. This
allows you to avoid false alarms triggered by short-term changes, for example cleaning
activities in the direct field of vision of the camera.
Global change
You can set how large the global change in the video image must be for an alarm to be
triggered. This setting is independent of the sensor fields selected under Select Area. Set a
high value if fewer sensor fields need to change to trigger an alarm. With a low value, it is
necessary for changes to occur simultaneously in a large number of sensor fields to trigger an
alarm.
This option allows you to detect, independently of motion alarms, manipulation of the
orientation or location of a camera resulting from turning the camera mount bracket, for
instance.
Global change
Activate this function if the global change, as set with the Global change slide control, should
trigger an alarm.
Bosch Security Systems
