license Starting auto recording on receiving an event from the motion detector

For normal mode:

Yes—if the camera is armed, the LPR channel scans all video images until the basic motion detection of the Axxon PSIM software 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 the Scripts used in the Auto PSIM software package section). Recognition will process frames until the stop command will be done

No—the LPR channel scans video images permanently
