Why does changing the camera’s relay pulse duration fail to keep an ANPR barrier open longer?

Answered by ANPR AI·Sourced

Short answer

The ANPR application can override the camera setting.

Explanation

Hanwha documents editing actionTimeout in the application’s exported JSON settings; the value is milliseconds.

Things to check

  • ANPR application configuration
  • ActionTimeout
  • Requested pulse

What to do

Back up and edit the application settings as documented, import them and restart the application. A value of 5000 represents five seconds.

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
