Overview
The VIVOTEK SC8131 is a stereo camera that provides precise tracking and people counting
functionality. The dual-lens stereo camera design eliminates the defects of single-lens cameras
in video analysis applications. Unlike single-lens applications that are easily affected by lighting
changes or shadows, this camera enables stereo visions that accurately tracks the 3D positions
of objects moving across the eld of view.
The stereo camera is ideal for collecting information for retails. The people counting and
trajectory detection applies in store layout improvement, queue management, and the control of
service times; providing precious information for business owners.
Featuring height filtering and height perception via the triangulation computation of images
acquired from two view points, moving objects can be effectively recognized. This enables
people of different heights, single or in groups, to be distinguished from non-human objects
such as shopping carts. Moreover, the computation of height disparity data takes place on
the camera, instead of sending video streams to a dedicated computer running an analytics
software. The solution saves bandwidth and reduces the chance of data loss in the event of
network or power downtime.
Supported by the VCA Report utility in VAST software v1.12, the data collected by this camera is
displayed in comprehensive graphs and line charts. You can monitor and compare the historical
data acquired through different time periods or among different surveillance areas with the ease
of use of a graphical interface.
The camera also supports ONVIF Video Analytics Service that includes object metadata, rule
engine, and counting events for development of 3rd party software. It displays 3D tracking
results in both live and recorded video in order to verify tracking and counting accuracy. It is
possible to customize analytic rules for various applications in addition to the counting utility.
Precision and accuracy:
• Stereo Camera with 3D Depth Technology • 98 % Counting Accuracy Rate
• Not Influenced by Shadows, Reflections or Small Objects • Bi-Directional Counting on configurable
detection lines
• Detection of U-turns to Avoid Double Counting
Revision History

Requirements for Running Stereo Tracking Video Analysis:
1. The recommended installation height ranges from 2.4 to 3.6 meters. If the camera is
unavoidably installed in a position higher than 3.6m, you can use the zoom-in mode
operation. Different lens provide different FOVs. See the FOV tables at page 9 for
details.
2. The embedded video tracking and counting analysis requires a monitoring session on
Microsoft IE 10 or IE 11 browser.
3. Lens cleanliness is also required because dust spots or smears on dirty lens can
produce miscalculation of pixels, correlation, and movements.
4. Avoid impacts to the lens modules. The relative positions of the lens have been carefully
calibrated in factory. Even if the lens positions have slightly changed, optical parameters
and stereo correlation will be affected, and then you should return the camera for a
repair.
5. For other installation concerns, please refer to page 13, Considerations.
6. Avoid glass and reective 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.
7. Make sure the camera is installed appropriately above the area of your interest, e.g.,
an entrance to building. Also use a leveling tool to make sure the camera is mounted
horizontally level.
8. Due to the system load, do not open two conguration web consoles at the same time.
IMPORTANT:
Refer to page 51 for the conguration details about the embedded Stereo Tracking and
Counting functionality.
NOTE:
• This camera is powered by a PoE switch or PoE injector. This equipment is to be
connected only to PoE networks without routing the the outside plant.

Considerations
Note the following when planning the camera installation:
1. The installation site must be adequately lighted for optimal accuracy with video analysis.
2. It is preferred that the camera is mounted directly above the objects to be counted. Use
tools such as a spirit level to ensure the camera is installed level.

Ceiling height - camera canister height (4cm)
4. The receommended installtion position is 2.4m ~ 3.6m. Higher position is also allowed.
For positions higher than 3.6m, you can also use the Zoom-in mode operation.
4-1. Use a spirit level to ensure the camera is installed level.
4-2. Use a laser distance meter to measure the installation height. The height
information MUST BE correctly measured and entered in the camera's conguration
page.
4-3. Please delete the height of the camera canister, e.g., 250cm (ceiling height) -4cm
(the height of camera canister) = 246cm. The reason for doing so is because the
lenses are at the lower edge of the canister.
3. By building a 3D depth map from an overhanging position, the objects' height information
can be acquired, and thus the drawbacks of 2D video counting can be eliminated.
The silhouette of heads and shoulders and their relative depth information enable the
camera to distinguish human activities from the background and other objects, such as
shadows, shopping carts, and dogs.

6. For counting to work properly, you should avoid having the view covering a large portion
of walls as shown below.

7. You can use the Exclusive area setting to get rid of the effects of some elements in the
scene. They include: white or bright surfaces, mono-color surfaces, mirror, glass door,
or reective materials that might introduce false images. Avoid covering the oor with
Exclusive areas.
6-1. Keep camera away from wall or other obstacles to optimize the effectiveness of
FOV.
6-2. Select a location that can cover a longer object trajectories for better tracking
results.

8. An effective counting requires an object to be detected, and then moves across the
detection line. Avoid setting the line too close to the edge of detection area.

9. By drawing the line slightly away from the place where customers make their
appearance allows enough space for recognition to take place. A start and an end point
across the line enable the movement to be considered as a count.
The stop point is where the object vanishes from the scene.

12. If the camera needs to be installed unavoidably at a position higher than 3.6 meters,
you can use the Zoom-in mode conguration. See the Stereo Tracker > Conguration
page. See page 51 for related parameters.
Note that if the Zoom-in mode is applied, the zoom-in factor should be set between 1

13. For Line Crossing and countng conguration, unnecessary objects should be avoided.
A door, a oating curtain, and moving objects such as an escalator can cause mistakes
with calculation.
14. If the VAST software is used for accumulating counting results, set the counting event
notication option to the "real-time" mode.
15. Apply to exclude some regions if the interference should occur near the object
trajectories. The camera might acquire incorrect depth estimation if its FOV covers the
following materials:
