## MxActivitySensor

The MxActivitySensor is a camera-internal video motion detector that can identify direction of motion detection and object size while blocking out any undesired interference (such as trees swaying in the wind) when detecting motion. There is an MxActivitySensor profile that is preset in the factory settings and contains all settings necessary to operate the MxActivitySensor.
You can activate and deactivate this profile here, change the name of the profile, adjust the event dead time, change the detection range and define new areas.

#### Active

The MxActivitySensor profile is also activated when the Arming feature is enabled in the general settings.

#### Profile Name

You can change the preset profile name.

#### Event Dead Time

The event dead time defines a period of time (0–3600 sec.) after an event during which no new events from the same profile are detected. By defining an event dead time you can avoid, for example, that a complex action (person walks through the active image area) triggers multiple events. You can adjust the preset event dead time (5 sec.).

#### Edit Detection Area

Proceed as follows to adjust the default detection area or to define additional image areas:
Click in the green detection area. You can execute the following actions with the icons that appear:

Action | Explanation
--- | ---
Change Size of Detection Area | Place the mouse pointer on one of the white squares until you see the icon. Then left-click with the mouse and resize the detection area making larger or smaller.
Move Detection Area | Place the mouse pointer on the detection area. Then left-click with the mouse to drag the detection area to the desired position.
Rotate Detection Area | Click on and right-click with the mouse to rotate the detection area clockwise or counterclockwise.
Change Shape of Detection Area | Switch to polygon mode by clicking on . You will see white corner points on the corners. Drag the corner points to the desired position. You can insert new corner points by right-clicking on the white line or in the detection area. Right-click on a dot to delete a corner point. Then click on .
Deleting a Detection Window | Click on .
Creating Additional Detection Window | Draw a new window with the mouse.
Blocking Areas Within the Detection Area from Analysis | You can define an area within the detection area that is blocked from the analysis. Drag a window corresponding to the size and position to the area that should be blocked from the analysis. Click in the window and keep the mouse button depressed until two icons appear. Click on to determine the exclusion window. The window turns red. Drag another window and position it so that it covers the desired detection area.
