Arabic characters (7.2.8.16)
Arabic characters (7.2.8.16) - for recognizing and identifying the plate's type, corresponding to Arabic countries.
China (7.2.7.79) - for recognizing and identifying the plate's type corresponding to China
Guatemala (7.2.7.103) - for recognizing and identifying the plate's type corresponding to Guatemala
Latin characters (7.2.8.24) - for recognizing and identifying the plate's type, corresponding to all European countries, including Russia.
Mongolian characters (7.2.7.86) - for recognizing and identifying the plate's type, corresponding to Mongolia.
Common characters (7.2.7.108) - for recognizing all the Latin characters of the plates (for example, relevant to such counties as Argentina, India, Africa and Singapore). The country recognition function is not used.
Common characters – quick (7.2.7.62) - for recognizing all the Latin characters of the plates in a rapid mode (for example, relevant to such counties as Argentina, India, Africa and Singapore). This value is a rapid variant of Common characters (7.2.7.108), but it is more sensitive to the quality of the image. Recommended to use only in optimal conditions as the recognition rate may decrease with a bad quality of the image.

Enable on motion detection trigger
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 untill the stop command will be done. No – the LRP 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 untill the plate will be recognizied and then will stop before new manual start. No – the LRP channel scans video images permanently |

The settings of the search area border affect the number of lanes on the video for the VIT and URAGAN readers. The number of lanes is taken into account when purchasing licenses for URAGAN, not the number of channels (VIT takes into account the number of channels). Therefore, if a 2FAST license is purchased (2 lanes, fast), then for a large search area, only one recognition channel will be created (however, URAGAN wil detact two lanes). In this situation, you should make the search area smaller. |
