Image Analysis Events

The Image Analysis Events dialog contains all event sensors that can trigger a camera action based on the results of an image analysis function.

Avoiding False Alarms

Meta Events

In order to filter events, the camera provides an Event Logic: This dialog allows linking events to create logic events only if the linked events occur in a certain sequence and within the specified time frame. Another possibility to filter events is the Event Counter: It creates an event only if a certain number of events occurs within the specified time frame.


General Settings

Option Description
Copy Window Definitions

If this option is activated, all window definitions (for video motion detection and MxActivitySensor) will be used on both image sensors. This option is only available on Day/Night models.

Dual Lens Analysis

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. An image analysis window that has been defined for the left image sensor will still be active, even if you only see the image from the right lens of the camera. This means that the camera will react on events detected on the left (invisible) image sensor. This option is only available on Dual models.

Event Dead Time

The event dead time defines a period of time (0 .. 3600 s) after an event during which no new events from the same profile are recognized.

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.

Description of Event Sensor Types

Event Sensor Type Description
Video Motion Detection

The video motion sensor reacts to movements in certain image areas, called "video motion windows". You can define one or more independent video motion windows for each image sensor (camera lens).

Open the Video Motion Detection help page for a detailed description of the parameters and application examples of this sensor.

MxActivitySensor

The MxActivitySensor sensor reacts to continuous movements in specific, freely definable image areas. You can define one or more independent of these analysis windows for every image sensor (i.e. camera lens).

Open the MxActivitySensor help page for a detailed description of the parameters and application examples of this sensor.


Storing the Configuration

Click on the Set button to activate your settings and to save them until the next reboot of the camera.

Click on the Factory button to load the factory defaults for this dialog (this button may not be present in all dialogs).

Click on the Restore button to undo your most recent changes that have not been stored in the camera permanently.

Click on the Close button to close the dialog. While closing the dialog, the system checks the entire configuration for changes. If changes are detected, you will be asked if you would like to store the entire configuration permanently.
