The settings panel of the LPR channel object

The settings panel of the LPR channel object includes the following interface elements:

№	Parameter name	Method of setting the parameter value	Description	Representation	Default value	Value range

			Selection of the country which numbers it is necessary to recognize	List of available national license plate templates	Depending on the recognition module	Depending on the number of available national license plate templates
	Module	Select the value from the drop-down list	For AR-Auto, AR-Railway software modules
			Selection of the license plate recognition SDK	List of license plate recognition SDK	Depending on the recognition module	Depending on the number of installed license plate recognition SDK
2	The Select cameras group
	LP recognition	Select the value from the drop-down list	Main video camera for license plate recognition	List of available Camera objects	Camera 1	Depending on the number of available Camera objects
	Synchronous shooting	Select the value from the drop-down list	Additional video camera operating together with the main camera	List of available Camera objects	None	Depending on the number of available Camera objects
	Automatic recording	Set the checkbox	Enabling the automatic recording on the LP number recognition	Boolean	Clear	Set—automatic recording enabled, Clear—automatic recording disabled
	Automatic recording, s	Enter the value in the text field	Setting the auto recording duration (in seconds)	Seconds	10	0-86400
	Process half frame	Set the checkbox	Specifying the frame processing setting	Boolean	Set	Set—smaller frame is stretched, larger frame is cropped Clear—smaller frame is stretched, larger frame is processed unchanged
	Enable on	Select the value from the drop-down list	Enabling and disabling LP recognition by main motion detection or by macros	List	Disabled	Disabled—LPR channel continuously scans the video image. By macros—enables LP recognition on macros. When you select this option, the Entrance and Exit drop-down lists become available. Motion detection—enables LP recognition on motion detection. Used to reduce the load on the server. It works differently depending on the selected recognizer mode. For normal mode: Yes—if the camera is armed, the LPR channel scans all video images until the basic motion detection of Axxon PSIM is in the Alarm mode. If the camera is not armed, the LPR doesn't work, but manual start using scripts is available (see item 6 in Scripts used in the Auto PSIM software package). Recognition will process frames until the stop command will be given. For Parking mode: If the camera is armed, the LPR channel scans all video images, until the plate will be recognized, after it recognition stops even if the Alarm mode is still in process and procedure repeats when the new trigger of alarm is activated; if the camera is not armed, the LPR doesn't work, but manual start using scripts is available (see item 6 in Scripts used in the Auto PSIM software package). Recognition will process frames until the plate will be recognized and then will stop before new manual start
	Entrance	Select the value from the drop-down list	Enabling LP recogniton	List	<no>	Depending on the number of created macros
	Exit	Select the value from the drop-down list	Enabling LP recogniton	List	<no>	Depending on the number of created macros
