VIVOTEK

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 field 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

■ Rev. 1.0: Initial release
■ Rev. 1.1: Added new features sush as event push, stereo tracking and counting results in
Liveview, and cloud services.
■ Rev. 1.2: Added information for Remote Management, Maintenance, and the Analytics Event
Manager. Modified some camera configuration details. Remove Event settings, because the
event notifications have been incorporated as part of the counting features.
■ Rev. 1.3: Reflected changes in firmware release v. 0101g, e.g., added fixed iris mode to
exposure setting, mod.sdp playback from SD card, and the removal of the default counting
line.
