Configure Blue Iris Motion Detection for ALPR

Option 1: Motion Sensor.  You can set the minimim object size (# pixels) to reflect a vehicle image in your camera. 
Make sure the default option (Highlight: Do not highlight the motion) is selected.  This way, Blue Iris will not include a rectangle in the image it sends to Plate Recognizer. 
Option 2: Object Detection.  In the Motion Sensor page (screenshot above), click on Edit in Object Detection.
Here, you can indicate that the object must travel for a specified number of pixels (e.g. 100). 
You can also have Blue Iris send an image to Plate Recognizer when the object crosses zones:
  • A Object must only have entered zone A
  • AB Object must have entered both zones A and B, overlapping or not
  • A>B Object must start in zone A, traveling to zone B
  • A-B Object must travel between zones A and B in either direction
  • AB>C Object must travel from zone A and B to zone C
Option 3: Zones.  You can create and edit zones.  Just click and drag to set areas of the image.
You can specify multiple zones.  Zones may or may not overlap.  In the screenshot below,
  • Zone A is the full yellow hatch marking.
  • Zone B covers the staircase.
  • Zone H (Hot Zone) is shown with the red hatch marking.  Zone H is for special applications and should not be generally used.
For more advanced motion sensor options that you may want to try out, refer to the Blue Iris PDF Support Doc. You can view the Support Docs by selecting Help within the Blue Iris application.  From there, navigate to Cameras > The Motion Sensor section.
