Mask settings

Select a camera from the Camera Pods window and click Masking. Masking is available only on the NetBotz Rack Monitor 570, 550 or on appliances for which the Advanced Software Pack has been purchased. For more information, contact your NetBotz authorized reseller or the NetBotz support team.

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:

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.
Show outline of detected motion	When enabled, any region of an image that indicates motion is
	surrounded by a dotted-line outline. This feature is not available
	with Pelco cameras.
Area of Motion	Specifies how large an area of the image capture must change
	(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.
Motion Detection Mask	Specify regions of the image to be ignored by the Camera Motion
	sensor.
	To mask a portion of the image, click and drag to draw a box around
	the region to ignore. Click Mask Selection. Red Xs appear in the
	region.

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 selected region are removed.
