Weigh Station LPR
Low-speed ramp

Real-time intelligence to accelerate inspection and throughput for commercial vehicle enforcement operations

Automated data capture supports informed decision making and speeds safety inspections to help enforce compliance and ensure safety is maximized.

The Perceptics Weigh Station LPR is a high resolution OCR imager designed to capture license plate data with high accuracy. The Perceptics Weigh Station LPR easily integrates with state or federal databases to enhance your overall commercial vehicle intelligence to include USDOT numbers, KYU, Motor Carrier and VIN numbers.  Our high performance imaging and data quality allows officers to check against multiple databases and screen larger populations of trucks to more quickly identify compliance violations and expedite inspections confidently.  

Our systems are proven to help commercial vehicle enforcement operations to:

  • Accelerate weigh station throughput
  • Reduce demand on weigh station facilities
  • Integrate with weigh-in-motion (WIM) data
  • Act as a force multiplier for your staff
  • Access real-time, accurate data to ensure roadway safety for all travelers

The Perceptics Weigh Station LPR captures commercial vehicle license plate data at up to 45 mph.
