How does ANPR Work in Car Parks?

ANPR, or Automatic Number Plate Recognition systems, are taking over parking lots today. With their advanced camera technology and intelligent software, car parks can easily monitor their packing lots, improving efficiency and productivity in several areas.

In this article, we’ll explore the ins and outs of ANPR parking management systems, their benefits, and the best license plate OCR API to build such a system.

What is ANPR?

ANPR, also known as LPR (License Plate Recognition), is a technology that uses optical character recognition (OCR) on images to identify and read vehicle license plates.

Simply put, ANPR scans an image or video to identify license plates and checks them for the actual plate numbers. This process can be used for several other purposes, such as allowing secure entry and exit into car parks, recording vehicles in your parking lot, and more.

To do this, the system usually needs:

• High-resolution cameras
• Powerful processors
• Sophisticated algorithms that can detect and extract license plate information from captured images.

How does ANPR Work in Car Parks?

You will most likely find cameras at the entry and exit points in an ANPR-enabled car park. They are installed where you would find barriers and are there to capture images or videos of vehicles as they enter and exit the premises.

During this period, the ANPR tech automatically recognizes license plates and the time and date. This data can be used to monitor parking duration, identify unauthorized vehicles, and enforce parking policies.

With ANPR, parking lots can also record data such as:

• Brand
• Class
• Color
• Model
• Speed, and more

What Are The Benefits of Using an ANPR Parking System?

There are several benefits to using an ANPR parking system. They include:

Automated monitoring

The main benefit of using an ANPR parking management system is that it saves time and minimizes effort. It is an automated system that requires little to no human effort in surveillance and recording license plate numbers.

This reduces staffing costs and saves time that can be used for other productive activities.

Tracking specific vehicles

Data from ANPR systems can be collected for all vehicles onsite on a particular day. When vehicles are monitored manually, data may be missed, but with ANPR, every detail is collected, and data for any vehicle can be tracked.

Automatic collection of tolls & parking fees

When connected to collection/payment systems, data collected from ANPR camera systems can help to collect tolls and parking charges directly from customer accounts without needing to touch their wallets.

Prevention of theft, vandalism, and illegal dumping

With ANPR, car parks can spot the license plates of all vehicles, identify stolen vehicles, and monitor hotspots 24/7 in ways that security personnel and law enforcement cannot.

Increased revenue

With ANPR, car park operators can introduce pay-to-park or pre-book parking options, generating additional payments and revenue streams.

Improved user experience

ANPR systems enhance the overall user experience for customers and visitors by improving the parking process and reducing instances of unauthorized parking.

The Limitations of ANPR in a Car Park Business

Like any technology, ANPR comes with its limitations. Although it has a lot of benefits, we cannot deny that there are a lot of areas of improvement. Now, let’s explore the limitations of ANPR and possible solutions:

1. Initial Costs

The installation and maintenance of ANPR systems can be expensive. This includes costs for high-quality cameras, software, and ongoing maintenance. For smaller car parks or businesses with limited budgets, these costs may not be justifiable compared to traditional parking management solutions.

Car park operators should conduct a thorough cost-benefit analysis before implementing an ANPR system. This evaluation should consider not only the initial setup costs but also the long-term savings and efficiency gains that ANPR can provide.

2. Connectivity Issues

ANPR systems require a reliable internet connection and a robust backend infrastructure to process and store data. In areas with poor connectivity, this can lead to operational challenges, including delays in data processing and potential system failures.

Investment in IT infrastructure will have to be made. This will ensure a strong internet connection and backup systems for maintaining data processing capabilities.

3. Privacy Concerns

The use of ANPR technology raises significant privacy issues, as it involves collecting and storing personal data related to vehicle registration. This can lead to concerns from users about how their data is being used and stored, potentially resulting in legal challenges if not handled properly.

Car park operators should comply with data protection regulations (like GDPR) and be transparent about data usage.

4. Technical Limitations

While ANPR technology has improved significantly, it is not infallible. Factors such as poor lighting, weather conditions, or obstructions can affect license plate recognition accuracy. Misreads can lead to incorrect fines or unauthorized vehicles being allowed entry.

To solve this, regular software updates and hardware checks are required, and cameras need to be positioned optimally to avoid obstructions and capture clear images.
