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.
- Exact Match: Enclose the query in quotation marks (e.g.,
- 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.
