Why does increasing my ACC LPR analysis rate fail to improve recognition?

Answered by ANPR AI·Sourced

The H4/LPR 6 guide says camera frame rate should meet or exceed engine analysis rate.

Things to check

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
