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.

For Parking mode:

Yes – if , until the plate will be recognized, after it recognition stops even if is still in process and procedure repeats when the new trigger of alarm is activated; if the camera is not armed, the the section plate recognized and then will stop before new manual start.No – permanently
