Access

  • When accessed via the administrative menu, as shown below, it can display hits from any LPR company and be grouped by company:

  • Ext sys ID: the unique system ID assigned to the hit by the LPR system
    • This is the LPR system ID that links hits with corrections (e.g., initial read by mobile LPR system and follow-up correction, such as 00000)
  • Proc stat: the status of the LPR hit assigned by Ranger, whether an interim step in processing or a final status
  • Created: time the LPR hit was created in Ranger, in Ranger timezone
  • Event time: time the LPR hit was created by the mobile LPR system, in customer timezone
  • Location: the location provided in the LPR hit
  • Processed: the last time the LPR hit was touched during processing in Ranger, in Ranger timezone
  • Company: the company name of the LPR company

    • Empty: new hit
    • V: violation created and linked
    • V+I:
      • violation created and linked
      • LPR images saved
      • System continuing to look for an LPR supplemental data match, in progress

    •  VCAN :
      • An LPR hit that indicates hit cancellation (e.g., plate that contains 00000) is received, and cancels any other hits that match on Ext sys ID.
      • If the hit with this status has a violation ID, that means a violation was in fact created and subsequently cancelled.
      • If no violation ID is listed, the hit was cancelled before a violation could be created.
    •  LPLM :
      • Error, local plate list match
      • The plate on the LPR hit was found on a Ranger local plate list, so processing of the hit is ended and no violation is created

        • A brand new permit was recently purchased, but has not yet been communicated from Ranger to Vigilant
    •  LPLMFUZZY :
      • Error, local plate list fuzzy match
      • The plate on the LPR hit was found on a Ranger local plate list using a fuzzy search
      • Fuzzy search considers the following character combinations as equivalent for matching purposes:
        • 0, O, and D
        • 5 and S
        • 8 and B
        • 1, I, and L
        • 7 and Z
        • V and Y
      • Processing of the hit is ended and no violation is created
      • Likely causes:
        • A brand new permit was recently purchased, but has not yet been communicated from Ranger to Vigilant
    •  VIOHOTLIST :
      • The hit resulted from a hotlist plate that was on the list for one or more ready violations
      • The hit will generate a notification to the spotter that the plate has one or more ready violations and can be towed
      • The hit will be statused as VIOHOTLIST so that it will not generate a new violatoin
    •  ERRML :
      • Error, multiple lots match LPR hit location
      • Processing of the hit is ended and no violation is created
      • Fixes:
        • Navigate to Lot spreadsheet screen and remove or edit the Vigilant location name in the Vig loc name column for at least one lot
    •  ERRNOLOT :
      • Error, no lot match
      • An error that indicates that no lot in Ranger matches the LPR hit location/lot name
      • Processing of the hit is ended and no violation is created
