Why does one Axis plate read produce New, Update and Lost events?

Answered by ANPR AI·Sourced

Short answer

These are stages of one tracked vehicle, not necessarily separate visits.

Explanation

Updates can change the OCR text or direction.

Things to check

  • CarID
  • Event state
  • Correction events

What to do

Merge the related events by carID within the camera’s tracking context. Update the existing visit instead of creating a new visit for every message.

ANPR Edge

Skip the dedicated ANPR camera. Read plates from the cameras you already have.

ANPR Edge is plate-recognition software that runs on a PC at your site and works with ordinary IP cameras, so plate reads no longer depend on one vendor's camera, NVR or firmware.

  • Works with standard IP cameras over RTSP
  • One license per location covers every camera
  • Runs on a Windows PC or Mac you own
