The traditional motion detection 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 Motion detection, with Human / Vehicle detection and
tunable time filter, can eliminate the defects of traditional motion detection and facilitate the
conguration at a surveillance site.
A key feature in the Smart Motion detection is the Human detection. Based on a human
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
humans or vehicles are the objects of interest in the majority of video surceillance, the Human
and Vehicle detection feature enables users to quickly congure his installation.
With Human detection, light changes or swaying vegetation, or animal activities in the scene
are not taken as event triggers. Only human or vehicle activities will trigger an event. This helps
reduce false alarms and the time and efforts for a camera conguration.

Revision History
■ Rev. 1.0: Initial release
■ Rev. 1.1:
* The Human Detection feature can be enabled/disabed on each individual motion window.
* Supports conguration in the MS9390 panoramic eld of view.
* If the Motion window is located outside of the optimal human detection area, the Human
Detection feature checkbox is automatically disabled.
* Motion window statuses have been adjusted. See page 20.
■ Rev. 1.2:
* Added the Vehicle detection functionality, and updated the reated UI changes.
A Short Comparison between Smart Motion and Smart VCA
Smart VCA rule is a 3D rule that is drawn on the virtual oor and needs to be triggered
within the detection area.
An object or human's feet must travel across various detection rules (line or zones) to
trigger an alarm. For example, if a person is detected as a human in scene, but his feet is
not in the detection area, he cannot trigger the rule.
In terms of Smart Motion:
The Smart Motion is an enhancement from traditional Motion Detection.
If the People Detection feature is turned off, Smart Motion works as a normal or more-agile
motion detection .
The triggering rule depends on how many motion cells have been activated in the
motion window. The rule does not consider human characteristics such as feet, head, or
shoulders.
When the People Detection is enabled, the human silhouette algorithms determines
whether it is human's presence or activities that triggered the motions in scene.
When enabled, human's presence within the motion windows will be a trigger.

Applicable Cameras:
Please refer to VIVOTEK’s VCA package and camera documentation on the website.
The majority of VIVOTEK’s latest camera models will come embedded with this utility.
Requirements for Running the Smart Motion Detection:
1. The embedded video tracking requires a monitoring session on Chrome, Microsoft Edge
browser. Note that Chrome does not support H.265 streaming.
If you open a console with a non-IE browser, the Smart Motion stream must be
congured to be streaming in MJPEG.
2. Lens cleanliness is also required because dust spots or smears on dirty lens can
produce miscalculation of pixels, correlation, and movements.
3. For other installation concerns, please refer to page 9, Considerations.
4. Avoid glass and reective materials, such as aluminum foils, in the eld of view. If
unavoidable, you can use the Exclusive area settings to get rid of the side effects.
5. Make sure the camera is installed appropriately above the area of your interest, e.g.,
an entrance to building. Installation at an extremely busy area, e.g., a square or cross
road section with dozens of passengers per minute, may not apply due to the system
computing load.
6. Due to the system load, do not open two conguration web consoles at the same time.
IMPORTANT:
NOTE:
1. The effectiveness of the Smart Motion detection slightly diminishes for objects lower
than 130cm, such as children.
2. The accuracy of vehicle detection is lower for large trucks or trailers. It works best for
smaller vehicles moving in a perpendicular direction to the eld of view.
3. For VCA running on MS9390, the VCA is turned off by default. When running VCA, the
frame rate will be reduced. You can manually turn on the VCA if preferred.
4. When using an HTTPS connection, you should stop and re-start the VCA after you
upload a license.
■ Rev. 1.3:
* Added the note for sharing the same Installation Reference function and the Settings >
Conguration window.

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 car 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 Motion works if additional lighting is provided, e.g., using the on-
board IR light.

3. 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 S-sensor. The height information enables the
horizontal and vertical keystone corrections of the eld of view. Measure the distance
between camera lens and the ground.
VIVOTEK
User's Manual - 5
3. 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.
Only part of the human is covered
by the detection area.

4. For Human detection, as long as a human silhouette is detected in the eld of view,
and his feet travelled through the Human detection area, he can be detected. Due to
the visual perspective of lens, sometimes the entire body may not be covered by the
detection area.

5. 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.

6. If the Human detection feature is not used, unnecessary objects should be avoided. A
door, a oating curtain, and moving objects such as an escalator can cause mistakes
with the detection.

8. Some other possible sources of interference may include: shadows on the wall,
mirrored object image on the reective surface.
7. The Human detection takes effects with standing or walking people. There is a limitation
that the detection may not handle more than 30 people in the eld. The eld of view
cannot cover a terraced structure or slope.

The roll angle is one that refers to the horizontal level line.
4. Enter the correct installation height. Please select the Auto mode for the camera to automatically
acquire the shooting angles (Tilt and Roll). Many of the VCA cameras come with a G sensor,
which allows an automated calibration. Users are not suggested to use the Manual mode to
congure the tilt and roll angles.
Should you observe unsatisfying readings from the Auto mode, select the Fixed option, and
Click on the Reference button for the camera to acquire the installation related parameters. The
Auto mode brings out the calibrated results, while the Reference function brings out the original
engineering readings by the G sensor.
If using models that are not equipped with a G sensor, you can manually enter the tilt and roll
angles. When done, click the Save button.

6. Observe the human or vehicle trafc on screen and tune the sensitivity until the motion
cells approximately match the human figures 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.

• Show Human Detection Area: Select to display the effective detection area currently
detected by your camera.
Due to the visual perspective of the camera mounted on a ceiling or wall, a person
enters the scene from the edge of the FOV with his feet appearing rst, and then his/
her head later. Only until he/she comes to a place within the perimeter of the detection
area, the head and feet positions can be aligned. A person's feet are detected rst, and
if a detection area is congured too close to the edges of FOV, a person may not be
appropriately recognized when his/her entire body prole has not entered the detection
area.
People crossing the non-Detection area may not be properly recognized by the Human
Detection function. Humans must have their feet stepping into or across the detection
area.
