DOT-HS: Mainline USDOT Number Reader System

Product Home

When You Need Commercial Vehicle Safety Enforcement on the Mainline.

If your commercial vehicle safety operations call for screening on the mainline, the DOT-HS is the only vehicle intelligence system that automatically captures vital USDOT, VIN, KYU and Motor Carrier numbers with 85% accuracy. The DOT-HS detects and images virtually every commercial vehicle traveling at highway speeds. Using this data, enforcement officers can check PRISM or SAFER databases for commercial motor carrier records. When you use the DOT-HS along with License Plate Recognition systems, states can check against multiple databases and screen larger populations of commercial vehicles on the mainline.

Benefits and Features

  • Captures USDOT, VIN, KYU and Motor Carrier numbers on commercial vehicles traveling up to 75 mph
  • Locates commercial vehicle data across a 15' wide field of view
  • Able to capture "hard to read" fonts such as scripted fonts or fonts with low contrasting
  • Scalable network architecture allows the system to be used as a "stand-alone" or integrated with other security systems
  • Integrates with the LPR-HR or other Perceptics vehicle intelligence systems
  • The only one with guaranteed read rates

USDOT number data captured by the DOT-HS can be correlated with data captured from License Plate Readers in an effort to check Federal or State DOT databases for commercial vehicle safety violations and registration information. With the DOT-HS, you can:

  • Automate screenings and enforcement efforts on the mainline or at virtual weigh station operations
  • Track and inspect commercial vehicles entering or leaving border crossings
  • Route and validate commercial vehicles entering or leaving seaports or container ports or marshaling yards, correlating data captured by the Perceptics Container Code Reader systems

DOT-EX for weigh stations



Inductive loop triggers

Uses two in-ground inductive loops to detect the front and rear of a vehicle passing through the configured inspection points. Requires 89-120VAC on one side of the lane to the loop controller housing. nearly 100% accuracy and impervious to weather conditions, loops are the most reliable triggering device available.

Laser Triggers

No road construction is required for lasers and their accuracy is nearly 100%. However, inclement weather can have a negative impact on their reliability to perform consistently.

License Plate Reader System

Perceptics' LPR-HR has a wide field of view and can capture license plate images and data from commercial vehicles. Images and data captured from license plates can be correlated with DOT number data. Click for LPR-HR product specifications.
