AXIS P3214-V Network CameraAXIS Video Motion DetectionNote• 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 secondsbefore the change is applied.• Enabling visual confirmation may introduce video latency.Ignore FiltersIf AXIS Video Motion Detection 3 detects too many unwanted objects, start by modifying the include and exclude areas. If still toomany objects are detected, use one or more of the ignore filters.Supported ignore filters:• 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 objectsIgnore filters are applied to all moving objects found by the application and should be configured with care to ensure that noimportant objects are ignored.Only use ignore filters if needed and use as few filters as possible. Enable and configure one filter at a time and use visual confirmationto verify the settings before enabling another filter. When configuring a filter, start with a small filter size, click Save and use visualconfirmation to verify the settings. If required, increase the filter size in small steps until the number of unwanted objects is reduced.Swaying Object Ignore FilterThe swaying object filter is used to avoid detecting objects that only move a short distance, for example moving trees, flags and theirshadows. Use the filter if such objects cause a lot of false detections. If the swaying objects in the scene are large, for example largeponds or large trees, use exclude areas instead of the filter. The filter will be applied to all moving objects in scene and, if set toa value too large, important objects might not be detected.When the swaying object filter is enabled and the application finds a moving object, the object will not be reported as detected (redpolygon in visual confirmation) until it has travelled a distance larger than the set filter size. The alarm sent by the application will besent when the object is detected. If the alarm is used to start a recording, configure the pre-trigger time so that the recording alsoincludes the time the object moved in the scene before being detected.To enable the filter:1. Select the Swaying objects option.2. Click on the icon to show the filter size in the image.3. Use the mouse to adjust the filter size. Start with a small size. Objects moving a distance shorter than the distance fromthe center of the cross to one of the arrowheads will be ignored. The filter can be moved to the location of a swayingobject to make it easier to adjust the size. Note that the filter will be applied to all objects in the image, not only to theones at the location where the filter is placed.4. Click Save to apply the filter.5. Use visual confirmation to verify the settings.6. If the result is not satisfactory, increase the filter size in small steps.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 thecenter of the cross to one of the arrowheads. The value 100 implies that an object must travel from its initial point to one third of theimage width or height before being detected. The value 50 implies half that distance, that is, the object must travel a distance ofone sixth of the image width or height before being detected.34
