The filter size can also be set by entering a value between 10 and 50 in the field. The value corresponds to the distance from the
center of the cross to one of the arrowheads. The value 50 implies that an object must travel from its initial point to one sixth of the
image width or height before being tracked. The value 25 implies half that distance, that is, the object must travel a distance of one
twelfth of the image width or height before being tracked.
Short-Lived Object Ignore Filter
The short-lived object filter is used to avoid detecting objects that only appear for a short period of time, such as light beams from a
passing car and quickly moving shadows. Use the filter if such objects cause a lot of false detections.
The short-lived object filter is used to avoid tracking objects that only appear for a short period of time, such as light beams from a
passing car and quickly moving shadows. Use the filter if such objects cause a lot of unwanted tracked objects.
When the short-lived object filter is enabled and the application finds a moving object, the object will not be reported as detected
(red polygon in visual confirmation) until the set time has passed. The alarm sent by the application will be sent when the object is
detected. If the alarm is used to start a recording, configure the pre-trigger time so that the recording also includes the time the
object moved in the scene before being detected.

To enable the filter:
1. Select the
Short-lived objects
option.
2. Click

.
3. Click
Enable
.
4. Enter the number of seconds in the field. The number of seconds is the minimum time that must pass before the object is
detected. Start with a small number.

starts. Start with a small number.
6. Click

8. Use visual confirmation to verify the settings.
9. If the result is not satisfactory, increase the filter time in small steps.
Small Object Ignore Filter
The small object filter is used to avoid detecting objects that are too small. For example, if only moving cars should be detected, the
small object filter can be used to avoid detecting people and animals.
The small object filter is used to avoid tracking objects that are too small. For example, if only moving cars should be tracked, the
small object filter can be used to avoid tracking people and animals.
If using the small object filter, take into consideration that an object far from the camera appears smaller than an object close to the
camera. If the filter is set to ignore objects the size of a person, people that are close to be camera can still be detected because
they are larger than the filter size.
