The MxActivitySensor reacts to continuous movements within specific image areas. You can define one or more independent image areas for each image sensor (camera image). Since the MxActivitySensor only reacts to relevant movements, events are triggered with a certain delay after the first appearance of an object. For recording, you can compensate this behavior by adjusting the Recording Time Before Event accordingly. Likewise, the measured activity fades away with a certain delay, which may prompt additional alarms. You can control this behavior by adjusting the Event Dead Time accordingly.
In order to obtain best results, the scene should be well-illuminated, so that the objects that are to be detected show sufficient contrast against the background of the image. In addition, you should choose the camera image in such a way, that the camera can follow objects within the detection area for several seconds.
By activating this checkbox, you can improve the detection of fast objects by MxActivitySensor. However, using this option can reduce the recognition results of small objects.
When activating this checkbox, the direction indicator is displayed in the live image. The direction indicator is not available for every display mode.
Displays the detection areas of the MxActivitySensor.
Every line in the definition box that does not begin with a hash sign (#, comments) defines one window.
Windows can be defined either as rectangles or as polygons.
Rectangle syntax:
[!]image sensor, horizontal position, vertical position, with, height
(optional parameters have brackets)
Example: 0,270,190,100,100
Polygon syntax:
[!]image sensor, poly=<hor. coordinate>x<vert. coordinate>{/<hor. coordinate>x<vert. coordinate>}
(optional parameters have square brackets, parameters that can be used as often as needed have curly brackets)
Example: 0,poly=270x190/270x289/369x289/369x190
Notes:
| Parameter | Description |
|---|---|

Defines an area that is excluded from detection. |
| Image Sensor | Selects the image sensor (camera image) to use for this window definition:
|
| Horizontal position | Position of the left window border measured from the left edge of the visible image in pixels (based on a MEGA image 1280x960). |
| Vertical position | Position of the lower window border measured from the lower edge of the visible image in pixels (based on a MEGA image 1280x960). |
| Width | Width of the window in pixels (based on a MEGA image 1280x960). |
| Height | Width of the window in pixels (based on a MEGA image 1280x960). |
| Horizontal Coordinate | Position of the left exposure window border measured horizontally from the left edge of the visible image to the polygon corner in pixels (based on a MEGA image 1280x960). |
| Vertical Coordinate | Position of the left exposure window border measured vertically from the bottom edge of the visible image to the polygon corner in pixels (based on a MEGA image 1280x960). |
Note: If you would like to define a new or additional window, open the Event Settings dialog and follow the instructions of the Graphically Entering Image Areas help page.
In order to temporarily deactivate windows, place a hash sign (#) in front of the definition. This window definition will still be saved, but will not be used as detection area. In addition, comments generally help keep an overview if the window definitions are complex.
This setting controls the sensitivity of the sensor. The sensor will trigger if the activity value exceeds the value entered in this field. Value range: 0..99.
Activate the directions of movement that will trigger reactions of the camera (e.g., recording).
If this option is activated, all window definitions will be used on both image sensors. This option is only available on Day/Night models.
Activating this option will detect video motion on both image sensors (regardless of which sensor is actually shown on the Live screen). Note that using this option may reduce the maximum frame rate. A window explicitly defined for the left image sensor will remain active, even if you only see the image of the camera's right image sensor. This means that the camera will react on events detected on the left (invisible) image sensor. This option is only available on Dual models.
