1.2 About this Manual
This manual is intended for persons who will operate IVA 4.0 or IVA 4.0 Flow. The manual
describes how to operate IVA 4.0 or IVA 4.0 Flow.

1.4 Intelligent Video Analysis
Bosch IVA 4.0 (Intelligent Video Analysis), with the auxiliary function IVA 4.0 Flow is an
algorithm that detects certain properties and the behavior of objects in a scene monitored by
a video camera and from this generates alarm events that, in turn, can be processed in a CCTV
system.
Recording with activated IVA 4.0 settings is required in order to be able to later search
through the video material quickly and purposefully using this algorithm.
IVA 4.0 makes it possible to capture and evaluate directional movement of objects in such a
way that false alarms are prevented to a large extent.
IVA 4.0 adapts automatically to changing environmental conditions and is therefore largely
non-sensitive to perturbing influences such as rain and tree movement.
Specifically when used for a forensic search, IVA 4.0 allows moving objects to be filtered
according to their color. Using the IVA 4.0 algorithm, extensive video material can be
specifically searched for objects with particular color properties.
New IVA 4.0 Functions
– Head detection: Objects can be identified as people by means of typical features.
– Similarity search: Objects can be detected on the basis of their similarity to other objects
that have already been classified.
– IVA 4.0 Flow auxiliary function: A uniform optical flow is detected largely irrespective of
the structure of the background and the size of individual objects. A flow in the opposite
direction to the general direction of movement can also be defined as an alarm-triggering
event.
IVA 4.0 Flow is used to detect uniform movement flows and movements against the
general flow.
CAUTION!
Security instructions where non-compliance can result in loss of data are marked with this
