To set up the detection of the LPR channel, do the following:

1. Go to the settings panel of the LPR channel object corresponding to the activated software module (see Activating the software module used for identifying the plates).
   

   The availability of the parameters depends on the activated software modules (for details, see The settings panel of the LPR channel object).

   
   

2. Enter the value in the Area search threshold field (1).

3. Set the Max. width and Max. height parameters:

   1. Click the  (2) button next to the parameters. Interactive interface of setting up the zone parameters showing the image from the corresponding camera will be displayed.
      

   2. At the appropriate moment, click the Stop video button and then hold the mouse while dragging it across the required area and click the OK button.

      

      You can select the zone in the Real Time Video mode as well.

      Results of setting the parameters will be automatically entered in the Max. width and Max. height fields.

      It is not recommended to set maximum sizes greater than required, as this slows down the processing, but does not improve the quality of recognition.

      
      

4. Set the Min. width and Min. height parameters similarly to the Max. width and Max. height parameters using the  button (3).

5. If necessary, set the Cut image with vehicle checkbox (4).

   The Cut image with vehicle option is used only when working with megapixel video surveillance cameras.

   
   

6. If necessary, set the Allow recognition by request checkbox (5).
7. Click the Apply button (6).
