ACC 6 Enterprise Datasheet

It is highly recommended that the self-learning feature be enabled for all video analytics devices, except in the
following circumstances:
• If you do not expect any humans or vehicles in the device's field of view.
• If humans and vehicles in the field of view move at multiple height levels, such as people on a staircase.
If the scene changes significantly, you may want to reset the self-learning settings. When self-learning is reset, all
previous self-learning data is deleted and the device learns anew. You may want to use this feature if a building
in the scene is demolished then rebuilt.
Enabling Self-Learning
The Video Analytics Configuration dialog box allows you to enable or disable self-learning in video analytics
devices.
1. In the device Setup tab, click .
The Video Analytics Configuration dialog box opens.
2. To enable self-learning, check the Enable Self-Learning box.
3. To disable self-learning, clear the Enable Self-Learning check box.
NOTE: Disabling self-learning may result in more classified objects being falsely detected.
Once disabled, the camera stops self-learning and no longer utilizes any learned information.
4. To reset self-learning, click Self-Learning Reset.
• In the confirmation dialog box that appears, click Yes.
NOTE: When self-learning is reset, all previous self-learning data for the device is deleted.
5. Click OK to save your changes.
Teach By Example
You can improve the accuracy of classified object detection by using the Teach By Example feature. You can
assign true or false Teach Markers to detected objects to help train the video analytics device.
Teach Markers can be assigned then applied to devices by different users. Users who assign markers to
detected objects are typically users who monitor video on a regular basis. It is recommended that 30 true and
30 false markers be assigned before they are applied to a device. Users who apply the markers to the device
may be an administrator who is less involved with day to day video monitoring.
NOTE: The Teach Markers are local to a single server and are created for individual cameras. They are not
shared between servers or cameras.
NOTE: Some features are not displayed if the server does not have the required license, or if you do not have
the required user permissions.
