Monochrome LPR
Superior Images
Greater Accuracy

Capture superior images with greater accuracy.  

The Perceptics Monochrome License Plate Reader captures ultra-high contrast monochrome images of license plates on personal and commercial vehicles, day and night, using filtered illumination. Perceptics LPRs have processed millions of images of vehicles from all U.S. and Mexican states and Canadian provinces. The system's flexible design ensures a seamless integration with current infrastructure.

When paired with other Perceptics imaging systems, officials have multiple vehicle datapoints with which to make informed decisions.

Product Highlights

  • 99.98% accuracy on over 85% of POVs
  • 95% accuracy on commercial vehicles
  • Captures state, province or country of origin along with alphanumeric characters of the license plate
  • Multiple wavelength illumination options available to optimize plate capture while maintaining driver safety
  • Multiple trigger and mounting options available
  • Can read multiple plates per image
