AXIS Video Motion Detection
Note
To use visual conrmation, Internet Explorer and AXIS Media Control (AMC) must be used.
When visual conrmation is enabled, all moving objects found by the application will be encircled and followed by polygons. A red
polygon indicates that the object is found and is detected as a moving object. A green polygon indicates that the object is found but
is ignored because it is not in the include area or because of one of the ignore lters.
To enable visual conrmation:
1. Select the Enable visual conrmation option.
2. Click Save.
Note
• Visual conrmation 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 conrmation may introduce video latency.
Ignore Filters
If AXIS Video Motion Detection 3 detects too many unwanted objects, start by modifying the include and exclude areas. If still too
many objects are detected, use one or more of the ignore lters.
Supported ignore lters:
• Swaying objects — Used to ignore objects that only move a short distance
• 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
Ignore lters are applied to all moving objects found by the application and should be congured with care to ensure that no
important objects are ignored.
Only use ignore lters if needed and use as few lters as possible. Enable and congure one lter at a time and use visual conrmation
to verify the settings before enabling another lter. When conguring a lter, start with a small lter size, click Save and use visual
conrmation to verify the settings. If required, increase the lter size in small steps until the number of unwanted objects is reduced.
Swaying Object Ignore Filter
The swaying object lter is used to avoid detecting objects that only move a short distance, for example moving trees, ags and their
shadows. Use the lter if such objects cause a lot of false detections. If the swaying objects in the scene are large, for example large
ponds or large trees, use exclude areas instead of the lter. The lter will be applied to all moving objects in scene and, if set to
a value too large, important objects might not be detected.
When the swaying object lter is enabled and the application nds a moving object, the object will not be reported as detected (red
polygon in visual conrmation) until it has travelled a distance larger than the set lter size. The alarm sent by the application will be
sent when the object is detected. If the alarm is used to start a recording, congure the pre-trigger time so that the recording also
includes the time the object moved in the scene before being detected.
To enable the lter:
1. Select the Swaying objects option.
2. Click on the
icon to show the lter size in the image.
3. Use the mouse to adjust the lter 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 lter can be moved to the location of a swaying
object to make it easier to adjust the size. Note that the lter will be applied to all objects in the image, not only to the
ones at the location where the lter is placed.
