ListDisabled

Disabled—LPR channel continuously scans the video image.

By macros—enables LP recognition by on macros. When you select this option, the Entrance and Exit drop-down lists become available.

Motion detection—enables LP recognition by 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 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 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

by LP position—the direction is determined by the position of the upper part of the LP number. If the upper part of the LP number at the start of tracking is lower than the upper part of the LP number at the end of tracking, then the direction is defined as From the camera, otherwise — To the camera.

by LP area—the direction is determined by the license plate area. If the LP area at the start of tracking is larger than the LP area at the end of tracking, then the direction is defined as From the camera, otherwise—To the camera.

by SDK—the direction is determined by the SDK. Currently, the following LP recognition modules support this mode:
