IVA Series Description
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 colour 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.
Intelligence-at-the-Edge Concept
Embedded Video Content Analysis (VCA), that decides which video is captured, is
an implementation of the Intelligence-at-the-Edge concept. By only selecting
alarm video for streaming or recording, less bandwidth and storage is used.
Alarm conditions can be signalled by a relay output on the unit or an alarm
connection, to stream video to a decoder or video management system. Alarms can
also be transmitted to a video management system to start extended alarm
scenarios.
As well as creating alarms, IVA 4.0 produces metadata that describes the content
of the analyzed scene. This metadata is sent over the network—and may also be
recorded—together with the video stream. It can be used for providing a forensic
search capability for recordings together with the Archive Player program and a
Forensic Search license. Forensic searching is very time efficient and can scan
a huge recording database for events within seconds.
Intuitive Graphical User Interface
A new wizard-based GUI guides you through the configuration with ease. The
Configuration Manager program with an intuitive plug-in is part of the product
CD and provides all the necessary tools to set up IVA 4.0.
A wizard-based graphical display within the IVA Task Manager, allows you to set
the sensitive area, size, speed, perspective, and aspect ratio as well as the
movement direction and object colour, which are then simply superimposed upon
the image.
The pick object functionality enables configuration to be carried out just by
clicking an object of interest in the live scene. All specific information
regarding size, speed, direction, aspect ratio, and colour are automatically set
for task configuration.
Up to eight independent tasks can be selected and combined in the scene to build
sophisticated detection rules, each one individualized with its own parameters.
This allows the detection of multiple object states in parallel, generating
separate triggers that can be handled independently or in combination. The
interface allows a flexible selection of each sensitive area through polygons
with up to 16 corner points.
A further improved calibrator is used for easy perspective correction and camera
calibration making measurements more accurate for both metric and imperial
systems.
When movement is detected, the object is outlined in yellow on the display and
motion is tracked on the monitor. If an object and its motion match the rule
conditions defined for one of the detector fields, it creates an alarm and its
outlines are switched to red. Additionally, an idle object is marked with an [I]
and a removed object with an [X].
IVA Series Installation/configuration notes
The IVA 4.0 software functionality is a free-of-charge upgrade of IVA 3.5 and
already part of all IVA 4.0 enabled-products with the firmware release of 4.0 or
higher. It upgrades automatically from an already installed IVMD 2.0, IVA 3.0 or
IVA 3.5 when installing the 4.0 firmware to the device. New IVA 4.0 customers
only need to enable the 4.0 license to make it operational.
The IVA 4.0 license enabling all IVA 4.x features, can be installed in parallel
with an IVMD 1.0 license on the same unit (not on VIP X1600 XF). IVA 4.0 is set
up using the Configuration Manager program that is included with the product and
available for download from the Bosch website.
Configuration Manager can be installed as often as required on any PC that will
be used for configuration of IVA 4.0 and the products themselves.
Video content analysis may require up to 40% of the available calculation power
of an encoder or camera. As priority is always given to recording and live video
streams, video content analysis may be affected if the calculation power it
requires is not available. Correct selection of encoder settings should resolve
this. The performance meter on the Web page of the product may be helpful for
set-up. IVA 4.x is not available for VIP X1 and VIP X2 because of technical
restrictions.
