| Enable on motion detection trigger checkbox | Set the checkbox | Starting auto recording on receiving an event from the motion detector | Boolean | No | For normal mode: Yes – if the camera is armed, the LPR channel scans all video images til the basic motion detection of the Intellect 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-Intellect 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 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 the Scripts used in the Auto-Intellect software package section). Recognition will process frames until the plate will be recognized and then will stop before new manual start. No – the LPR channel scans video images permanently | |||||||||

This setting is taken into account in the Intellect Web Report System when working with Auto reports (see Intellect Web Report System. User Guide). | ||||||||
