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
