Binding Cameras to Plug-in

Configuring Per-Camera Plug-in Settings

After binding the plug-in to cameras the links will appear under Bound Cameras for each camera. Click a link (for example Edit “3. Hallway”) to edit the settings for that camera. The following settings should be configured for each camera bound to the Demographics plug-in:

Drawing Demographics Inclusion Zone

For each camera that is bound to the Demographics plug-in, you may define one or more zones that will be used for Demographics analysis. The zone name will be appended to the Demographics event that appears in OpCenter. Drawing a zone becomes essential when:

• The camera covers an area where Demographics analysis is not desired. For example, if the camera covers a checkout line, you might draw a zone that excludes the cashier.

• You wish to isolate areas in the field of view that might generate different demographics data. For example, a store with a camera covering two end-cap displays might want to compare the demographics of people attracted to each display. Note: this use case is typically only relevant when using a megapixel camera with a wide field of view.

• Faces appearing in front of the camera are in the field of view for a long time, as in a long hallway. In this case, you might draw an inclusion zone only for the closest half of the camera to avoid
  accidentally counting the same person twice. The image to the right exhibits this use of a zone.

Zones are specified in the Zones tab of the Edit Settings window. To create a new zone:

1. Click the polygon icon.

2. Click the video player to begin drawing a zone. Each click of the mouse will create a new line segment. To complete the polygon,
   click the mouse over your start position.

3. Edit the polygon by clicking and dragging its end points. Sections of the polygon may not overlap.
   In this example, we have drawn a Demographics zone in the center of the hallway.

4. When the zone has been created, edit the Name of the zone and make sure that [ ]Enabled is checked.

5. Repeat for any remaining zones you wish to draw in the field of view. The area outside of an inclusion zone will be ignored.

Setting the Eye Distance

The Eye-to-Eye Distance setting should be configured on each camera bound to the plug-in. This setting helps the Demographics
plug-in identify and analyze faces. It can also be used to filter out background faces, if the faces in the foreground are substantially
larger. To set the Eye-to-Eye Distance:

1. In the Edit Settings window, click the Parameters tab.

2. Wait until a person appears on camera, then click the pause button.

3. Click and drag the orange box until it covers both of the person’s eyes. The positioning of the box in the video player is irrelevant.
