Select a camera from the Camera Pods window and click Masking. Masking is available only on the

Camera-based motion sensing compares concurrent image captures and determines whether any detected
changes are significant enough to generate an alert. An alert is generated only if observed changes meet
the criteria specified by both the Sensitivity and Area of Motion settings.
For Pelco cameras, custom settings are available to set the Sensitivity and Area of Motion more
precisely. Setting these values too high or too low can produce constant motion detection alerts, or no
alerts, depending on the camera.
Note: If you have the Advanced Software Pack installed, this window also features a Block
Out Mask tab.
Motion mask tab. The following controls are available:
To unmask a masked region, click and drag in the image to draw a box around the region you want to
unmask. Click Unmask Selection to remove the mask from the selected region. Red Xs displayed in the

Field Description
Enable Camera Motion Check to enable the camera motion sensor.
For Pelco cameras, the camera motion sensor is enabled by default.
Sensitivity Specifies how much change in a portion of the image capture is
tolerated before the change is considered movement. Lower values
indicate higher sensitivity and less tolerance for change between
images.
For Pelco cameras, an additional custom setting is available to set
the Sensitivity % to a value from 1 - 100.

(based on the Sensitivity value) before the change is considered
movement. Lower Area of Motion values indicate higher sensitivity
and smaller areas.
For Pelco cameras, an additional custom setting is available to set
the Area of Motion to a number of16x16 pixel blocks from 1 - 100.
