Automated Licence Plate Reader (ALPR)

Automated Licence Plate Reader (ALPR) technology, also known as Licence Plate recognition, provides automated detection of vehicle licence plates. An ALPR is used by Bylaw Enforcement Officer’s to monitor vehicles that are parked within time restricted zones and have stayed beyond the posted time limit.

Frequently Asked Questions

An ALPR replaces the manual process of chalking a vehicle and collecting evidence. The automated system reduces staff time and improves efficiency in monitoring timed parking zones.

Time restricted zones can be located on streets or within municipal lots and are signed indicating a time restriction for the corresponding location.

How does an ALPR work

  • An ALPR system, which is mounted on a bylaw vehicle, drives by vehicles parked within a time restricted zone
  • The ALPR system automatically captures an image of a vehicle's licence plate
  • Wheel imaging cameras digitally chalk a vehicle, collecting evidence (photo and gps coordinates) for future follow up
  • Upon a follow up drive through of the time restricted zone, the ALPR will identify and alert a bylaw officer of a violation
  • A bylaw officer may enforce a violation by issuing a bylaw offence notice
