Examples of macros used for license plate recognition

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 first create and configure the automatic number plate recognition detection tool (see Category: Vehicle). You should also select the speed value as km/h in the detection tool settings.

Specify the following values:

• SpeedKmph—in the Parameter (1) field.
• Specify the minimum (2) and maximum (3) speed values in km/h within which an alarm will be triggered when recognizing a license plate.
