Marking Systems Solves Nighttime License Plate Reading Challenge for Motorola Solutions
CHALLENGE
Motorola Solutions, a leader in mission-critical communication, needed a solution for their license plate recognition (LPR) cameras used by law enforcement. Standard lens covers blocked infrared light at night, hindering the camera’s ability to read plates. The challenge was to create a cover that allowed over 93% infrared light transmission.
Difficulties:
- Existing lens covers blocked 30% of infrared light, exceeding the desired threshold.
- Standard IR inks used in electronics blocked even more infrared light.
HOW WE SOLVED IT
Our R&D Director, Razvan Datcu, implemented a two-part approach:
- Infrared Ink: We sourced a unique infrared ink with a significantly higher transmission rate. Unlike standard and UV inks, this ink cured via air or heat, making it ideal for the application.
- Optical Acrylic: We utilized “Optix,” a highly transparent acrylic known for its exceptional clarity and used in museums to protect paintings. This material offered superior light transmittance without deflection.
RESULTS
The combination of the unique infrared ink and Optix acrylic exceeded Motorola Solutions’ requirements. The final product allows over 93% infrared light transmission, ensuring unprecedented low light performance for accurate license plate and vehicle make and model recognition
