    Licence Plate Recognition (LPR) Capture Log

    The Licence Plate Recognition (LPR) Capture Log is a tool designed to track, filter, and audit real-time and historical license plate reads. The system supports automatic data ingestion from fixed camera feeds as well as manual or mobile inputs from parking enforcement users. 

    To find this log go to Violations, then LPR and Chalking, and click View Events.

    1. Search and Filtering Interface

    The top section of the log provides comprehensive query filters to locate specific plate records.

    Filter Fields
    • Plate: Allows for full or partial plate number inputs.
      • Exact Match: Enclose the query in quotation marks (e.g., "ABC123") for strict matching.
      • Fuzzy Search: Selecting the Perform Fuzzy Search checkbox enables approximate string matching to catch optical character recognition (OCR) anomalies or close variations.
    • Make: A dropdown selector to filter by specific vehicle manufacturers (e.g., NISSAN, HYUNDAI, FORD). Defaults to "Any".
    • Colour: A dropdown selector to filter results by vehicle color. Defaults to "Any".
    • Start Date / Up To and Including: Date pickers to define a strict search window.

    The Start Date and Up To and Including parameters only restrict results generated by Pay Station data and LPR records. These filters do not retroactively filter out base vehicle profiles based on their original database creation date or account history.

    Clicking the Toggle More Options button expands the interface to reveal advanced metadata filters. These options allow administrators to isolate specific hardware feeds, integration streams, and capture events.

    • Cameras: A multi-select scroll menu used to filter logs by specific physical entry or exit lanes. This is critical for tracking a vehicle's exact movement pattern. Options default to ANY or can be filtered by specific installations, including:

      • Entry Points

      • Exit Points

    • Event Type: A dropdown menu used to filter logs by:

      • Entry

      • Exit
      • Patrol
      • Tracking

    • Device Type: A multi-select scroll menu to filter entries based on the software agent or integration platform delivering the LPR data. Options include:

      • ANY: Broad system-wide search.

      • PL8RDR / Vaxtor:Vaxtor: Specific integrated LPR software engines.

      • User / Other:Other: Manual enforcement inputs or unclassified mobile devices.
