Detecting Motion by Metadata (VMF)
If the camera supports motion detection metadata,
configure settings related to the VMF (Video Motion
Filter) to use for motion detection by metadata.
VMF is a filter for detecting specific motion phenomena
from motion-related metadata generated within the
camera. There are VMFs for motion and object detection, and up to
three VMFs can be managed together as one VMF
package. The filters in a VMF package can be combined
either sequentially, whereby each filter must be satisfied in
sequential order to trigger an alarm, or in parallel, whereby
satisfying any one filter is sufficient to trigger an alarm.
Overview of Motion Detection by Camera Image Metadata
* Metadata includes time and camera information, and location, type, and status of motion.
• To perform motion detection and object detection using
metadata, a camera that supports motion detection by
metadata is required.
• When using VMF motion detection with the [Existing]
filter type, the alarm state is maintained after object
detection for as long as the object continues to be
present. As a result, if a second alarm is triggered in this
state, alarm recording will not start. When you want
NSR to record the second alarm, select [Event Start] in
the schedule settings
(page 84) . This ensures that
everything is recorded during the alarm period,
including the second alarm.
• When object detection metadata is processed, the object
detection status is maintained for approximately three
hours after detection, but the VMF detection status is
cleared after approximately ten seconds.
• A VMF package can only process the live camera image
of one camera at a time.
• When metadata is recorded, either motion detection
metadata or object detection metadata is selected, based
on the VMF being applied at the time. The order of
priority is determined as follows:
1
If something has been specified in the alarm recording
schedule, priority is determined by whether the VMF
package is for motion detection or object detection.
2
If a VMF package is not specified, priority is
determined based on the default package.
3
If a default package is not specified either, the
metadata is recorded as motion detection metadata.
Object detection requires an approximately 40 second
initialization period before starting. Also, moving objects
that have remained still for approximately 40 seconds are
regarded as unattended. These times may be extended
depending on the circumstances.
