Winter conditions put LPR systems to the test. Snow, ice, road salt, glare, and low light can reduce read accuracy, increase service calls, and lead to missed reads. These challenges are especially common with IR-only LPR cameras that rely heavily on plate reflectivity, which often degrades in harsh weather.
The CT-45 LPR camera from TagMaster North America is built specifically to perform in real-world conditions. From salt-covered and damaged plates to low-contrast or non-reflective backgrounds, the CT-45 delivers consistent, reliable plate recognition without requiring additional enclosures or environmental protection.
Built for harsh winter environments
Snow and road salt quickly reduce plate reflectivity, causing IR-only cameras to struggle. The CT-45 addresses this by combining infrared and color imaging in a single, all-in-one LPR camera, delivering reliable reads when conditions are far from ideal.
By capturing two simultaneous perspectives of every plate, the CT-45 maintains accuracy as lighting and weather conditions change throughout the day and across seasons.
Dual IR and color imaging in one housing
The CT-45 features two onboard cameras, one infrared and one color, capturing synchronized images of each vehicle. When salt, grime, fading, or specialty plate designs reduce IR performance, the color camera continues to capture usable plate data. Onboard OCR processes both image streams together to deliver accurate recognition without manual intervention or retuning.
This means:
- Dirty, damaged, or salt-covered plates remain readable
- Reflective or low-contrast backgrounds are normalized
- Specialty and non-reflective plates no longer compromise accuracy
A smarter alternative to IR-only LPR
Traditional LPR systems depend almost entirely on infrared illumination. When reflectivity drops, accuracy drops with it. The CT-45 takes a different approach, using dual imaging and onboard processing to adapt dynamically to changing conditions, maintaining performance where IR-only systems fall short.
The result is higher reliability in winter weather, dirty environments, and regions where plate materials and designs challenge conventional LPR cameras.
Higher confidence for demanding applications
For applications requiring maximum reliability, two CT-45 units can be paired to create a single high-confidence read event using four optical inputs: IR and color, front and rear. This approach improves data quality, reduces missed reads, and increases system uptime in snow, fog, and low-visibility conditions.
Winter introduces reduced visibility, optical distortion, and environmental stress. The CT-45 is purpose-built to maintain performance, uptime, and data quality when conditions are unpredictable. With a compact hardware footprint and powerful onboard processing, the CT-45 delivers consistent, dependable results where accuracy matters most.
