The fourth generation of the Bosch Intelligent Video
Analysis system, IVA 4.0, is the guard-assistant system of
choice when you need reliable video motion detection for
indoor or outdoor use. IVA 4.0 is state-of-the-art intelligent
video analysis that reliably detects, tracks, and analyzes
moving objects while suppressing unwanted alarms from
spurious sources in the image.
IVA 4.0 is a licensed option already fully prepared in
Dinion IP, Extreme IP, FlexiDome IP, and AutoDome IP
cameras, as well as the VIP X1600 and VideoJet X families
of encoders. The functionality built into IVA 4.0 cameras
and encoders is able to detect idle and removed objects
as well as loitering, multiple line crossing, and
trajectories.
IVA 4.0 supports head detection as a new feature. And
Bosch for the first time also supports optical flow
detection of objects in a video surveillance scene.
Configurable detection filters and advanced tracking
improve reliability and reduce operator work load. IVA 4.0
comes with the new enhanced calibration tool to allow
the calibration of the camera within a few minutes.
Functions
Robust Motion Detection
The improved algorithm in IVA 4.0 intelligently adapts to
difficult conditions like changes in lighting or environment
such as rain, snow, clouds, and leaves blowing in the
wind. The background learning algorithm is continuously
developed in-house by the Bosch research group and
brings the latest level of intelligence to IVA.
The increased functionality combines with the built-in
tamper detection that generates alarms on camera
hooding/masking, blinding, defocusing, and repositioning.
Image stabilization ensures detection even with shaky
video sources such as cameras mounted on poles or
simple vibrations.
The following tasks can be selected:
•
Detect objects entering, leaving, or just being within
an area (detector field)
•
Detect loitering in an area related to radius and time
•
Detect idle objects within a configurable time span
•
Detect removed objects within a configurable time
span
•
Detect trajectories/routes of objects, passing in the
scene, displayed with tracking lines
•
Detect multiple line crossing from single line up to
three lines combined in a logical row
•
Detect condition change properties such as size,
speed, direction, and aspect ratio change within a
specified time span (for example something falling
down)
•
Detect heads within a configurable area
•
Detect flow of a constant moving object
•
Detect object that moves against a flow of objects
•
Alarm task script manager in the expert mode to
combine tasks logically
Filters
It is easy to configure IVA 4.0 to select sensitive areas of
the image, minimum object size, and the motion direction
that will trigger an alarm. IVA 4.0 will only detect the
relevant moving objects in a scene. Use the object size,
speed, two-way direction, aspect ratio, head detection
and color filters to create specific detection rules. These
filters can be used in any combination to exactly
determine the object features you are looking for.
Detection statistics for objects are stored for fine tuning
the object filters.
