Choosing the Best License Plate Recognition Camera: Key Features to Look For

Traffic enforcement through effective surveillance, facilitated by the deployment of advanced number plate recognition software, has been a pressing need. However, many providers on the market claim to offer the most reliable ANPR systems. Are you having trouble choosing the best?

This blog helps you select the best traffic enforcement camera by drilling down into the crucial technical features you should consider. Let’s begin.

Must-Have Features in a License Plate Recognition Camera

While choosing the best ANPR camera, you must consider the following features:

Image Quality

The primary function of an LPR camera is to capture images or videos of vehicles. Therefore, your traffic camera should produce high-resolution photos or videos, so that the system can easily process them further by enlarging, cropping, and taking large prints with finer details, without losing clarity and overall quality.

Capability to Capture Images in Challenging Conditions

Can the number plate recognition camera capture high-quality images (and videos), even in challenging conditions? Low luminous intensity and adverse weather conditions, including fog, snow, and poor air quality resulting from air pollution, can impact image quality.

Robust Infrared Capabilities for Night Vision

Can the car plate recognition camera continue capturing high-quality images at night? Look for infrared illuminators and additional LED flash units to ensure clearer image capturing at night.
Traffic enforcement is critical, and your ANPR camera system must complement the efforts of your teams to ensure compliance with traffic laws at all times.

Real-Time Recognition Mechanism

Does a reliable number plate recognition software back the ANPR camera? Reliable and accurate license plate recognition requires a technology-driven mechanism to:

• Process the image or video,
• Separate the license plate by removing other elements in the background,
• Fine-tuning the license plate image by adjusting brightness, contrast, angle, and sharpness,
• Further divide it into characters,
• Recognize characters based on region-specific rules and logic, and
• Convert the characters into a machine-readable, structured format for further processing. (The most preferred data structures are JSON and XML.)

Strong Image Processing Power

Refer to the product technical details and configurations to ensure the number plate recognition camera system is compatible with various popular processors. Compatibility with Intel CPUs, NVIDIA GPUs, and Halio-8 implies a strong processing power.

See if the provider offers comprehensive documentation, an SDK for seamless integration, and API key-based access. These technical aspects make integration into your traffic enforcement, surveillance, access control, and parking management systems smoother.

Additionally, verify if the ANPR system offers cloud-based and edge-based deployment options to meet your technology requirements.

The Bottom Line

Considering the features of the license plate detection camera, as briefed in this blog, will help you make an informed decision. Comparing various ANPR systems based on these parameters will help you pick the best-suited solution for your operational needs in the long run.
