How to find the best PRE-POST values each vega camera


  1. Set both values to 0 (zero)
  2. Drive with a car slowly to the barrier.
    The camera will now be triggered with 0ms PRE and 100ms POST duration. This means with 12fps the camera will take only 1 image. AnprFairPark will store this image in the configured Archiv Directory.
  3. Check this picture. You will have the exactly point in time where the presence loop activates. Depending where this is - adjust PRE- and POST time according.
  4. After a few hours or days check the image results again. Sometimes you have to adjust the time again to get best results in short time.
