  3. In the Parameter field, specify the required parameter.

    Note
    titleAttention!

    The parameter value is case-sensitive.

  4. Depending on the parameter used, in the Value and Max value fields, set the range of values ​​within which the macro starts.

  5. Set one or more actions to be performed (see Examples of macros).

  6. Click the Apply Image Added button.

The clarifying parameters are set.

Example of a license plate recognition when a vehicle is approaching the camera or moving away from it

You can configure a macro to initiate an alarm if a license plate is recognized when a vehicle is approaching or moving away from the camera. To configure this macro, you must first create and configure the License plate recognition RR detector (see Configuring License plate recognition RR).

In this case, an alarm is initiated when a license plate is recognized while a vehicle is moving away from the camera.

Example with speed detection

You can configure a macro to initiate an alarm if a vehicle

Example for approaching the camera or moving away from it

You can configure a macro to trigger an alarm if a license plate number is recognized when approaching or moving away from the video camera. To configure this macro, you should first create and configure the license plate recognition (RR) detection tool (see Configuring License Plate Recognition RR).

Specify the following values:

  • Direction—in the Parameter (1) field, "1"—in the Value (2) field and "1"—in the Max value (3) field to trigger an alarm if a license plate number is recognized when approaching the video camera;
  • Direction—in the Parameter (1) field, "2"—in the Value (2) field and "2"—in the Max value (3) field to trigger an alarm if a license plate number is recognized when moving away from the video camera.

Example for speed determination

You can configure a macro to trigger an alarm if a license plate number is recognized at a certain vehicle speed.To configure this macro, you should must first create and configure the automatic number plate recognition detection tool (see Category: Vehicle Vehicle recognition RR detector (see Configuring Vehicle recognition RR).You should must also select the speed Speed detection value as km/h Kmph in the detection tool detector settings.
