Introduction
IVMD (Intelligent Video Motion Detection) is a software
algorithm that detects movements of objects within an environ-
ment monitored by a video camera and generates alarm events
that can be processed further in a CCTV system.
IVMD makes it possible to capture and evaluate directional
movement of objects, thereby largely preventing false alarms.
IVMD adapts automatically to changing environmental condi-
tions and is therefore non-sensitive to perturbing influences
such as rain and tree movement.

Limitations
Please note the following considerations:
IVMD is suitable for monitoring boundaries, fences and enclo-
sures and for the protection of pipelines, overland lines etc.
However, in certain environments the use of this type of motion
detection system may not always be advisable; this is because
movements may not always be detected or too many move-
ments may be detected owing to reflections.
Movements may be falsely detected if there is:
–
–
–
a reflective metal background
glass (glazed building frontages)
water as a background
Large areas of reflected light can also cause spurious motion
detection. However, light reflections caused by falling rain-
drops, for example, are small enough to be ignored for statisti-
cal purposes and owing to the uniform nature of their motion.
Objects that always move uniformly (such as clouds) do not
impair the detection of other objects and do not trigger false
alarms.
A constant background is necessary in order to detect motion
reliably and to assign that motion to a certain object. The more
the background moves, the harder it is to distinguish moving
objects from it. For instance, a person walking in front of a
hedge that is moving in the wind will very probably not be
detected.

IVMD | Configuration instructions
If the image consists to a certain extent of nothing but moving
objects – in other words if objects cannot be distinguished
from each other or from the background – the motion of an indi-
vidual object cannot be detected (e.g. individuals in a large
crowd).
If a very large number of objects are detected, a lot of comput-
ing power will be required – this will reduce the power that is
available for the transmission of live video data. If necessary,
change the settings so that only relevant objects are detected.
IVMD and the associated configuration menus offer a number of
simple ways to overcome these limitations and eliminate prob-
lem areas.
This means that you will be able to use IVMD reliably in a wide
range of applications.

Alarm state
This field shows whether IVMD has generated an alarm event
with the current settings.
Object markings
Objects that generate an alarm event under the current settings
appear on the camera image inside a red outline.
Objects that are detected as moving but do not generate an
alarm event under the current settings appear inside a yellow
outline.

NOTE!
These object outlines are displayed in real time and are always
synchronized exactly with the moving object. However, because
the camera image is not live video feed, the outline does not
always exactly surround the object.

The basics
The camera 'sees' a selected area that is displayed as a single,
constantly refreshed image.
Objects
Objects are typically people or vehicles moving within the area
seen by the camera. Objects can be filtered according to cer-
tain properties (size, direction of movement, speed, location).
An alarm event can be generated if objects match certain
parameters. Objects that do not match the criteria you define
are filtered out and do not generate an alarm event.
It is always the center of an object that is relevant for generat-
ing an alarm event.
Detector fields
Detector fields are polygons that cover a certain area, for exam-
ple an entrance or the open space in front of a barrier. These
detector fields are defined by you. Moving objects that are out-
side the detector fields will be detected as such but will not
generate an alarm event. Objects that move inside detector
fields or across detector field boundaries (depending on your
settings) will generate an alarm event.
Sensitive area
The scene that is captured by a camera often includes areas
that are irrelevant for alarm event generation (such as sky).
You can reduce the size of the area that is actually analyzed for
motion. This will make motion detection for the remaining –
sensitive – area all the faster and more effective.

Calibration
If you wish to filter out objects according to their size or speed,
for each camera position a link must be made between the size
of the real-life situation and the dimensions as they appear on
the camera image. For example, you must tell the software that
an object that appears on the camera image with a height of
50 pixels is around 2 m high in reality. The camera angle is used
to compute object speeds. The calibration mode is available for
this operation.
NOTE!
Display of measurements can be adjusted, so that when using
the English software interface imperial measurements are
shown. You will find additional information in Section 5 Display
of Measurements, page 38.

When you click a detector field, its 'nodes' (corners) are high-
lighted by circles and you can edit the detector field.
Nodes can be inserted or deleted. The sides and nodes of a
detector field can be repositioned as desired. However, the
sides of a detector field must not cross over, and distorted
fields are not accepted.

Up to 16 detector fields each with up to 16 nodes can be cre-
ated for each camera image.
For each detector field you can specify that only objects with
certain properties will trigger an alarm event. These config-
urable properties include:
–
–
the speed at which the object is moving
the motion of the object relative to the detector field
(inside, leaving, entering)
–
–
the direction in which the object is moving
the size of the object (the area covered)
For example, you can configure the monitoring of an entrance
and exit so that only large, fast-moving vehicles leaving the
detector field trigger an alarm. Small, slow-moving people will
not trigger an alarm.

mum size for all objects that will generate an
alarm event. Objects that are smaller or larger
than the specified sizes will be ignored and
this will save computing power as a result.
Make sure that the range between the mini-
mum and maximum size is not too small, or
relevant objects may be unintentionally elimi-
nated from alarm generation.

Calibration
Calibration is only necessary if you want the speed and size of
detected objects to be interpreted correctly. You do not need
to perform this step if you do not want objects to be filtered on
the basis of these two properties.
In the calibration mode, a virtual horizontal plane is overlaid on
top of the camera image:
The virtual plane appears as a blue grille and can be tilted,
rotated and scaled. Position the virtual plane on the camera
image so that it matches the angle and perspective of one of
the actual horizontal areas.
NOTE!
Display of measurements can be adjusted, so that when using
the English software interface imperial measurements are
shown. You will find additional information in Section 5 Display
of Measurements, page 38.
i
Two red cubes are shown at opposite corners of the plane.
In the default setting, the side length of one of these cubes is
equivalent to 2 meters, so the cube is about the same height as
a person. The cubes are shown in the perspective of the blue
plane.
You can adjust the position and size of the cubes – so that a
cube corresponds to a car, for example.
A section of a street is a suitable reference area, especially if
the sides of the street are marked.

Position one of the red cubes over an object that you wish to
trigger an alarm event. Adjust the cube to the size of this object.
The second cube changes its size to suit the selected perspec-
tive. You can place the second cube over another object of the
same type, for example a second person who is further back in
the image.
The more care you take over calibration, the more accurately
the size, direction and speed of moving objects can be esti-
mated.
You can of course alter your settings at any time.
NOTE!
The system must be recalibrated each time the camera position
is changed.

tings of each parameter simply by entering the required values.
Tilt angle:

IVMD | Configuration instructions
Roll angle:
The angle by which the calibration plane is tilted.
The setting can deviate from the horizontal by up to 10 degrees.
Elevation:
The vertical distance from the camera to the ground plane of
the captured image – typically the height of the mounted cam-
era above the ground (in meters).
Camera constant:
The camera constant determines the basic settings for calibra-
tion. The default value of 1000 is preset and should only be
adjusted if the actual camera constant significantly deviates
from this preset. The camera constant is used to compensate
spherical distortions from the combination of image sensor and
lens.
The camera constant is a function of the focal length of the
camera's lens and the pixel pitch of the image sensor. It is cal-
culated with the following formula:
Camera constant = focal length [mm]/(pixel pitch [mm] x 4)

Area settings | en 27
The pixel pitch is obtained by dividing the image sensor size by
the number of pixels. For sensors with 596 pixels, for example,
this gives:
1/2 inch: 5.95 mm/596 = 0.0100 mm
1/3 inch: 4.96 mm/596 = 0.0083 mm
1/4 inch: 3.69 mm/596 = 0.0062 mm
For such a 1/4 inch image sensor with a 28 mm lens:
camera constant = 28 mm/(0.0062 mm x 4) = 1129
For a 1/3 inch sensor with a 12 mm lens:
camera constant = 12 mm/(0.0083 mm x 4) = 361
NOTE!
If you change the camera constant, you must also change the
size of the cubes to suit the actual relative sizes in the image.
i
Cube size:
Side length of the cubes (in meters).
A side length of 2 m (6 ft) corresponds approximately to the
height of a person.

Properties of a detector field
The Properties of Detector Field dialog is opened from the
context menu of the Area settings window (refer to page 19).
In the dialog you can specify the properties of objects for which
this detector field will generate an alarm event. Objects that do
not match the selections made here will not trigger an alarm. In
other words: Objects are filtered according to their properties.
Only objects that match all filter criteria can trigger an alarm
event (filter criteria are logically linked with AND).
Meaningful settings will help to prevent false alarms. If you are
concerned that objects will not generate an alarm event even
though this would be desirable for those objects, refer to the
descriptions given in Section 4.6 Statistics, page 36.

Objects cannot be detected according to their properties
unless the system has been calibrated for the current camera
position (Section 4.3 Calibration, page 21).
Object size filter
Only objects whose size (captured area) is between the
entered limits can lead to the generation of an alarm event.
A person corresponds to around 0.5 m²; a car to
around 4 m².
Objects are not filtered by size.
Object motion filter
Only objects moving at a speed between the entered limits
can lead to the generation of an alarm event.
The speed of a movement crossways to the camera can be
determined much more accurately than the speed of a
movement directly toward or away from the camera.
Objects are not filtered by speed.
Object moves crossways to camera:
speed is detected more accurately
Object moves in camera’s line of sight:
speed is detected less accurately
NOTE!
Select generous filter settings for object size and speed so that
all relevant movements lead to an alarm being generated.

...the center of the object moves across the
boundary of the detector field and into the
field.
Debounce time: If a value other than 0
(zero) is selected, the alarm event will not
be generated until the center of the object
has fully crossed the boundary of the
detector field after this time. This prevents
objects triggering a large number of alarm
events when they are moving around on
the edge of the detector field.
Leaving
Inside
...the center of the object moves across the
boundary of the detector field and out of
the field.
Debounce time: as for entering objects,
see above.
...the center of the object moves inside the
detector field.
Delay [s]: If a value other than 0 (zero) is
selected, the alarm event will not be gener-
ated until the object has moved or been
inside the detector field for at least the
selected delay time.
NOTE!
If the boundary of the detector field lies across a static object
that can conceal a moving object (e.g. advertising hoarding),
entering or leaving may not be detected.

If you have activated Direction under Show in the context menu
of the Area settings window (see page 19), the direction filter
and the motion filter will be graphically displayed for each
detector field:

The direction field can also be repositioned with the mouse in
the graphic display.
You can change the tolerance angle with the mouse by moving
the cursor directly onto the side of the direction indicator and
then moving it with drag&drop.

An object motion filter (if set) is shown by additional moving
white (maximum limit) and yellow (minimum limit) squares
being displayed inside the direction indicator.

Grapic display is adjusted to the size of the detector. For better
visibility, either create a detector large enough or resize the
whole window.

Sensitive area
The sensitive area is that part of the image seen by the camera
that is analyzed. Objects moving outside the sensitive area can-
not generate an alarm event even if they are caught by the cam-
era.
Only objects moving inside the sensitive area are detected as
such and generate an alarm event.
The larger the sensitive area, the more computing power is
required, and data will be processed more slowly.
A smaller sensitive area means that data processing is faster.
The sensitive area is shown in yellow hatching.
In the default setting, the whole of the image captured by the
camera is defined as the sensitive area. Any areas that consist
of small squares can be defined as non-sensitive (or again as
sensitive). There are four editing tools you can use for this pur-
pose. You can also repeat this operation as often as you like to
achieve a very precise definition of the sensitive area.

Sensitive area
Examples of areas that could be defined as non-sensitive:
–
Railroad: Passing trains can trigger unwanted motion
alarms.
–
Public streets: Passers-by moving across a public space
should not be detected – in order to save computing
power and prevent unwanted false alarms.
Neighboring properties.

–
Areas in which moving objects are not anticipated.
Sky: Birds or planes can trigger false alarms.
Trees or bushes that move in the wind.

Statistics
The statistics for a detector field help you to refine the filter cri-
teria for objects. For example, you may see an accumulation of
objects that have not triggered an alarm under the current filter
criteria even though this might have been desirable.
You can view the Statistics dialog separately for each detector
field. To create the displayed statistics, start by opening the
dialog. The longer the dialog is left open, the more data will be
entered in the statistics.
Green:
Set of objects
with no alarm
Red:
Set of objects
with alarm
Black:
Filter area that
allows alarm
Gray:
Filtered-out area;
no alarm
The statistics show three histograms:
–
–
–
Area: accumulation of objects with a certain surface area.
Speed: accumulation of objects moving at a certain speed.
Direction: accumulation of objects moving in a certain
direction.
The black area in each histogram is the area that was defined in
the Properties of Detector Field dialog for the particular filter

(see page 28). Areas that are outside the defined limits are
grayed.
The lines indicate the number of objects for which the respec-
tive value was detected. The higher the line, the more objects
matched the particular criterion. The histograms distinguish
between objects that trigger an alarm (red line) and those that
do not (green line).
