Smart VCA provides the following features:
Crowd detection, Intrusion detection, Loitering detection, Missing object detection,
Unattended Object detection, Line Crossing detection, Face detection, Parking
Violation, Restricted Zone, and Running detection.
These features can suffice a wide variety of surveillance needs in different scenarios. The
feature package comes with fixed dome, bullet, or fisheye cameras to fit various installation
sites. They can be used to mointor ofce buildings, retail stores, industrial assets, for areas less
attended by security staff. VCA Events are incorporated into VIVOTEK’s VAST software and
NVR, enabling rapid search through the archived footages. The instant video prompts enable
security personnel to quickly react to potential problems.
Minimized No. of False Alarms: An important factor in the Smart VCA is a human and vehicle
silhouette database and the rapid responses via an artificial neural network technology. The
Smart engine instantly recognizes human appearances in a video surveillance area. Since
people and vehicles are the objects of interest in the majority of video surveillance, the People
detection feature enables users to quickly congure their installation.
The traditional video contents analysis relies heavily on the detection of pixel changes or motion
vectors, and false alarms can be triggered by swaying trees, clouds floating by, or even the
appearance of little animals. The Smart VCA detection, with comprehensive detection rules
and tunable time lter, can eliminate the defects of traditional video detection and facilitate the
conguration at a surveillance site.
Ease of Configuration: With the self-learning algorithm, light changes or swaying vegetation,
or animal activities in the scene are not taken as event triggers. Only activities worth notice
will trigger an event. This helps reduce false alarms and the time and efforts for a camera
conguration.
Reduced Management Efforts: Integrated with VIVOTEK’s VAST software, the VCA events can
be tagged as video clips, making the forensic search effortless. With ordinary video recordings,
it often takes hours to search for meaningful videos from the archives. With the VCA tagged
events, searching for the related evidences is reduced to a matter of minutes. The correlation of
events on different cameras are available at a glimpse as tagged events in the VAST Alarm list.
If users choose to record the videos only when VCA alarms occur, the bandwidth and storage
requirements can be minimized. Also, the detection and analysis takes place on individual
cameras, instead of being processed on a dedicated server. There is no need for an expensive
server hardware, and the use of network bandwidth for transmitting videos is reduced to
minimum.

Considerations
Note the following when planning the camera installation:
1
. The installation site must be adequately lighted for optimal accuracy with video
detection. For example, a black bar in a shaded area may not be adequately detected.
2
. In the night mode, congure a schedule prole for the different lighting condition. In
the night mode, the Smart VCA works if additional lighting is provided, e.g., using the
on-board or external IR light. Avoid obstructions that can reect IR lights back to the
camera.

.
IMPORTANT
: Make sure you measure the height of your camera. The height
information is important for the accuracy of the video analytics results. Some of the other
perspective information are automatically collected by the onboard G-sensor. The height
information enables the horizontal and vertical keystone corrections of the eld of view.
Measure the distance between camera (ceiling where it is mounted) and the ground.
For bullet cameras or
wall-mounted domes,
measure the distance
from the lower edge of
the camera canister to the
ground.
VIVOTEK
User's Manual - 17

. Because the horizontal and vertical keystone corrections are performed for an accurate
detection, the height and tilt information of the camera must be correctly congured.
Use a laser distance meter to measure the installation height. The height information
MUST BE
correctly measured and entered in the camera's conguration page.
The sheye cameras can also run the Smart VCA feature and they
MUST NOT BE
mounted on a tilted ceiling, nor can they be installed on a wall. The camera
MUST BE

. A man sitting, squated, or men lying on the oor may not be detected as a human,
because his silhouette has been destroyed. Detection may also be affected when
a human form is changed, e.g., a man's body is hidden behind a counter, or a man
showing only the upper half of his body by leaning on a desk.
• Due to the optic concave characteristics of a lens, men can be temporarily blocked
behind other men. When a man's head-shoulder feature is consealed, he may not be
detected for the short moment. The analytics is not designed for a very crowded area.

. Some other possible sources of interference may include: shadows on the wall,
mirrored object image on the reective surface.
8
. The Human detection takes effects with standing or moving objects or people. There is a
limitation that the detection may not handle more than 15 people in the eld. The eld of
view should not cover a slope or terraced structure, either.
10
. Small and distant objects may not be properly detected.
11
. Detection accuracy can still be affected by severe weather, such as heavy rains.
12
. Ensure the camera is properly mounted. Excessive vibration, such as that when
mounted on a pole, can affect the detection accuracy.
13
. If fast moving objects are expected, use a wider FOV to enable a longer observation
time.
14
. Contrast between the object and the background cannot be too low. A black car in a
very shaded area may not be detected.
15
. The camera has been moved or re-installed after the detection conguration.
16
. Incorrect installation: the camera is too far away from the detection zone.

a speed faster than threshold is
considered as
running
.
The speed parameters are
determined by the size of your
FOV. In a wide open scene where
people are smaller, you can tune
the speed threshold lower. In a
near scene where people appear
larger, you can tune the speed
threshold higher.
VIVOTEK
38 - User's Manual
It is recommended to have a co-worker to run in the scene when you are conguring the speed
threshold. Try test the effectiveness by observing the human trafc in scene. Observe and
use the speed threshold tab to change the threshold. A speed faster than level 5 will still be
displayed as level 5. 0 means static.
Due to the wide variety of view perspectives, zoom ratio, near-far distances, and the very
complex parameters involved, there is currently not a single calculation rule for how fast is a
running in the view area of your interest.
Another notice is that while people are moving around, the silhouette of one man can be blocked
by another during their movements, and hence the detection can be interfered.
The indicators on the Speed level chart indicate the detected activities. They do not represent
the number of people walking or running in the scene.

• People detection, Vehicle detection, Object detection
: In real-world applications, the
effectiveness of VCA detection can be affected by the following:
• Fast moving, running in the scene,
• Lingering at the edges of FOV,
• People crouching or crawling.
In such situations, users can consider tuning the sensitivity towards "
Less missing
objects,
" or vehicle, people.
On the contrary, if tuned towards "Less false alarms," the detection algorithm will apply
more strictly human or vehicle silhouette matching. In some situations, such as when a
man crouchs down to pick up an object, he will be temporarily undetected.

The VCA detection results appear immediately on screen (depending on the activities and
inputs in the scene).
You may need to enter

to tune the VCA sensitivity settings if
detection does not perform as your expectation. Note that these Sensitivity parameters
are shared between Smart VCA and Smart Motion detection.

match the human gures on screen. If you aim to detect larger objects, such as vehicles,
the same applies. Tune the sensitivity so that the appearance of motion cells better
coordinates the appearance of the objects of your interest.

Shown below is the comparison of the same object detected through different sensitivity
levels. At the sensitivity level 90, excessive motion cells can be observed; while at level 30, the
detection ends up with insufcient motion cells.

When People detection is disabled, different conguration options will appear.
Motion activity
: The detected human activities is displayed on a 1-minute time line. The
consecutive 4 standing man icons indicate a detected presence persisted for 4 seconds.
Note that when watching the activities, the Motion activity displays for a selected window. If
you have multiple detection windows, and a window is currently not selected on screen, its
activities do not display.
When activities occur, and the window is triggered, the window will be highlighted by
turning the frame into red.
Time lter
:
Minimum activity duration
: A human activity (or moving objects) must persist for
longer than this duration to be considered an effective trigger. This aims to avoid the
situation when one enters and leaves the scene very quickly.
Activity merge interval
: Setting this interval aims to avoid the stop-and-move
maneuver by some thieves. The activities occurred during this duration is considered
as one trigger. If activities occur before the end of the interval, the interval will be
prolonged, e.g., 7 + 7 seconds.
If activities occur before the end of
this interval, the inconsecutive actions
will be considered as one trigger.

the event prompt can play back the related video footage.
VCA events are tagged and can be retrieved from the event list using the Alarm Search
function.
The search function has the following benefits:
1. Faster search: Metadata is saved with videos coming from cameras running Smart
VCA detection. With the help of the metadata, the search focuses on the effective
alerted vectors and the adverse effects, e.g., headlights causing dramatic contrast
or small animals passing through, have already been eliminated by the camera. The
search can be more rapidly completed.
2. People detection: The search can be conducted for human activities only. Activities
matching the silhouettes of human will be considered as effective results.
3. Multiple multi-point polygons: Users can more readily create flexible polygons on the
areas of their interest.
Note that the detection areas must have been configured on each camera before the
VCA search can take effect.
