AXIS Video Motion Detection
When visual confirmation is enabled, all moving objects found by the application will be outlined. A red outline indicates that the
object is found and an alarm is triggered. A green outline indicates that the object is found but is ignored because it is not in the
include area or because of one of the ignore filters.
To enable visual confirmation:
1. Select the Enable visual confirmation option.
2. Click Save.
Note
• Visual confirmation is disabled after 15 minutes.
• After modifying a setting, click Save to apply the change. The video stream will be restarted and it may take a few seconds
before the change is applied.
• Enabling visual confirmation may introduce video latency and affect performance during configuration.
Ignore Filters
If AXIS Video Motion Detection 3 detects too many unwanted objects, start by modifying the include and exclude areas. If too many
objects are still detected, use one or more of the ignore filters.
Supported ignore filters:
• Short-lived objects — Used to ignore objects that only appear in the image for a short period of time
• Small objects — Used to ignore small objects
• Swaying objects — Used to ignore objects that only move a short distance
Ignore filters are applied to all moving objects found by the application and should be configured with care to ensure that no
important objects are ignored.
Only modify ignore filters if needed and use as few filters as possible. Enable and configure one filter at a time and use visual
confirmation to verify the settings before enabling another filter.
When configuring a filter, start with a small filter size, click Save and use visual confirmation to verify the settings.
Modify the filter values in small steps until the desired result is achieved.
Swaying Object
The swaying object filter is used to avoid triggering alarms for objects that only move a short distance. For example moving trees,
flags and their shadows. Use the filter if such objects cause a lot of false alarms. If the swaying objects in the scene are large, for
example large ponds or large trees, use exclude areas instead of the filter. The filter will be applied to all moving objects in scene. If a
value is set too high, important objects might not trigger an alarm.
When the swaying object filter is enabled and the application finds a moving object, the object will not trigger an alarm until it has
travelled a distance larger than the set filter value. 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 triggering an alarm.
To enable the filter:
1. Select the Swaying objects option.
2. Click on the
3. Use the mouse to adjust the filter size. Start with a small size. Objects moving a distance shorter than the distance from
the center of the cross to one of the arrowheads will be ignored. The filter can be moved to the location of a swaying
object to make it easier to adjust the size. Note that the filter will be applied to all objects in the image, not only to the
ones at the location where the filter is placed.
