Top 10 Questions to Ask when Evaluating LPR Vendors: A Complete Buyer's Guide
Choosing the right License Plate Recognition (LPR) vendor can make the difference between a security system that transforms your operations and one that becomes a costly burden. Whether you're in law enforcement, managing a facility, or running a parking operation, these ten essential questions will help you cut through the marketing speak and make a choice you won't regret.
License Plate Recognition (LPR) has become a vital tool for security agencies and businesses alike, helping them boost security measures and streamline operations to improve throughput and efficiency.
As the technology continues to evolve, it becomes increasingly important, making it crucial for organizations to evaluate vendors across various parameters and invest in the right LPR partner and solution, because no one wants a system that’s just good at capturing vehicle data most of the time.
Add to this the fact that there is a cost associated in terms of time, money and efforts, in setting up an LPR system and integrating it into your ecosystem, and you cannot just keep changing the vendor every other day, month or even year.
It’s a little like choosing a sidekick in an action movie - pick the wrong one, and you’ll end up doing most of the heavy lifting. A reliable vendor will not only deliver cutting-edge software, but also provide comprehensive support and timely enhancements to ensure the system delivers value well into the future, without any unnecessary headaches and last minute plot twists.
This guide will walk you through the top 10 considerations to keep in mind while evaluating LPR vendors that can support your long-term goals.
1. What Is The LPR Vendor’s Expertise and Experience in the LPR Field?
The first step in evaluating an LPR vendor is to assess their expertise and track record. Look for vendors who have a solid history in the LPR business with a sizeable list of respectable clients.
Ask for case studies or examples of successful deployments in different industries and in a variety of indoor/outdoor scenarios. You should also carry out reference checks with a few of the vendor’s clients to learn how their experience was. These real-world examples will give you insights into how the vendor’s system performs and its ability to deliver results.
It will be ideal if they have any clients that have needs very similar to yours. This proven experience in handling similar scenarios will demonstrate that they can meet your requirements effectively. If not, you need to assess if they have the ability to understand your particular use case and associated problems, and then deliver a fitting solution.
Additionally, pay close attention to the reports and analytics the system generates and whether it translates LPR data into actionable insights to support decision-making. Ask for a product demo using sample data relevant to your use case to fully understand the quality of the reports and analytics provided.
2. How Advanced Is The LPR Vendor’s AI and Machine Learning Capability?
When evaluating a vendor’s AI and machine learning capability in LPR systems, it’s important to look beyond lab results. While accuracy metrics from controlled environments can be useful, field performance in real-world conditions is far more telling. Ask vendors to demonstrate their system in challenging scenarios such as poor lighting, high-speed traffic, or adverse weather, and assess how well it captures different data points. A hands-on demonstration is often the best way to determine if the system can meet your operational needs.
Additionally, it's critical to understand how the system handles complex situations like plate swapping, convoy detection, and low-visibility conditions. These advanced analytics are vital for law enforcement and security agencies. The vendor should be able to explain how their AI-driven system processes these challenges and provides accurate reports and insights.

3. What Is the LPR System's Accuracy and Performance in Challenging Conditions?
Ask the vendor if they have any study that has been carried out to demonstrate the accuracy of their system in capturing data in varying and challenging conditions like inclement weather, insufficient lighting, fast moving traffic, etc., and at different times like day, night and twilight.
Check which data points their system captures, like license plate number, state or province, vehicle make, model, type and color, direction of travel, and any other types of objects like bumper stickers, bicycles, etc.
Evaluating system performance can be divided into 2 buckets. The first is capture rate, where we see the data of what percentage of vehicles that passed in front of the camera were captured by the system. The second is accuracy, where we see the percentage of correct data captures out of the total captures made.
Accuracy can also be subjectively assessed by first deciding which data points are of primary importance to you, and in which can you accept the possibility of errors. For example, a system might very accurately capture vehicle make, but not the specific model. If that satisfies your use case, then in that aspect, the system can be considered ‘accurate enough’.
Another point to be kept in mind is, some English language characters look extremely similar to each other, especially when seen from a distance and/or a harsh angle. For example, the characters D, O, Q, and 0. However accurate a system might be, there will be circumstances when the difference between these characters won’t be discernible in the real world.
4. How Scalable and Customizable Is The Vendor’s LPR Software Solution?
When evaluating a long-term LPR partnership, you need to ensure that the system is easily scalable and can grow with your needs, whether you are expanding operations, increasing coverage, or requiring more complex data analysis. For example, if you are growing from 100 cameras to 200, the system might need to be upgraded on several fronts. But has it been designed for growth? A scalable system will be able to handle a much higher data volume without compromising performance.
There is a considerable expense involved in setting up an LPR system and getting it functioning smoothly along with any required integrations. If that system isn’t scalable, you might end up temporarily running parallel systems, which could complicate operations and lead to data loss during transitions.
Getting a scalable system in place certainly needs planning, as not only will you have to figure out more hardware (cameras, servers), manage connectivity (wired or wireless), and arrange for greater compute power (CPUs or GPUs), but you will also have to change data storage and other components at the backend, which can become quite complex.
Since each server has a limit to how many cameras it can process concurrently, expanding coverage will call for more servers and related connectivity. Additionally, any changes in your data retention policy, like keeping data for 60 days instead of 30, will affect your storage requirements.
As your system grows, you might also need advanced technologies like clustering to ensure reliability. Clustering helps provide redundancy and protection against hardware failure, ensuring continuous uptime but adds complexity and an exponential increase in cost.
The best way to plan is to take stock of your current requirements and do a forecasting exercise to estimate how much your LPR needs will grow over the foreseeable future. Once you have a good picture of your projected growth patterns, design the system accordingly.
You might end up with a larger system and a higher outlay upfront, but it will save you a lot of money and frustration down the road, as you will be much more future-ready.
Customization is another key consideration. Most custom requests focus on reports and analytics, as raw data alone is not as valuable without meaningful insights. It's essential that your vendor can modify data views and provide actionable insights tailored to your operational needs. While some customizations may be bundled into the initial pricing, more complex or unique requests might involve additional costs, depending on the intricacies of the customization and the vendor's specific policies. Be sure to clarify these details upfront.
5. What Data Security Measures Does The LPR Vendor Offer?
Data privacy laws: It is important to make sure that the vendor’s system complies with the latest data privacy laws and has robust encryption protocols in place. This includes adherence to regulations like GDPR or other regional laws that protect personal information. Prioritizing data security is critical to preventing breaches and unauthorized access to sensitive data. Encryption should be applied both in transit and at rest, ensuring that all information is secure, whether it's being transmitted or stored.
Sensitive information: Determine if the vendor’s system provides regular software updates and patches to address vulnerabilities. If you're hosting the data on-premise, data security becomes a shared responsibility between your team and the vendor. Both sides must ensure that all systems, from software to physical security measures, are well-maintained to avoid exposure to cyber threats or unauthorized access.
Data storage location: Knowing where your data is stored is crucial. LPR data can be stored on-premise or in the cloud, each with its pros and cons. On-premise storage allows for more control and can be beneficial in highly secure environments but comes with higher long-term costs and the need for regular hardware refreshes. Cloud storage, on the other hand, is more cost-effective, scalable, and easier to manage, but it places your data on third-party servers, requiring trust in the vendor’s data handling practices.
Data access: It’s important to clarify who has access to your data and for what purposes. Some vendors may resell aggregated data for marketing, insurance, or law enforcement purposes, which can help lower costs but might raise privacy concerns depending on your business needs. Carefully review contracts to ensure that the vendor’s data-sharing practices align with your privacy requirements and goals. Verify who can use the data and ensure that any additional usage aligns with your company’s policies.
Data retention: Ask how long you can retain your data and consider whether you actually need to keep it for extended periods. Storing large amounts of data for a long time can be costly and may expose your organization to greater risks. It’s often more efficient to retain aggregated data, such as vehicle counts or high-level reports and analytics, rather than raw data. Establish a clear retention policy that balances your operational needs with the cost and risks of maintaining large datasets.
Augmenting data with other sources: Some LPR systems augment their data by integrating information from other sources, like records from the Department of Motor Vehicles. While this can enhance the dataset, such as adding vehicle identification numbers, it also introduces the potential for inaccuracies if data is mismatched. Be cautious when augmenting data and ensure that the system’s data-matching criteria are robust. Additionally, consider how the LPR system handles enhancements, such as delivering color information for vehicle images taken at night, which might be inferred from previous daytime readings.
6. What Support and Maintenance Services does the LPR Vendor provide?
Support and maintenance are crucial considerations for LPR systems due to their upfront costs and long-term functionality. Since LPR systems involve both hardware and software components, it’s important to ensure that ongoing maintenance and support services are in place to protect your investment. Hardware like cameras and sensors are exposed to the elements, meaning they can degrade over time due to solar exposure, temperature changes, humidity, and other weather conditions. Regular in-the-field maintenance is required to keep these systems operational and in good working condition. Additionally, most organizations schedule tech refreshes every 3 to 5 years to ensure equipment is in good working condition and up to date.
The relevance of hardware to current technology is another factor. A computer or camera purchased today may be outdated in just a few years, struggling to support newer software. Planning for hardware refreshes ensures that your system remains compatible with evolving technological requirements. It’s important to have a clear understanding of the maintenance schedule, whether provided by the vendor or managed internally, to ensure long-term system efficiency.
Support is equally important. Environmental factors like storms, lightning strikes, or accidents can cause damage to the system, making quick repairs and support essential. Discuss the level of support required with your vendor, including Service Level Agreements (SLAs) that cover downtime and replacement times for damaged equipment. A 24-hour SLA, for example, will be significantly more expensive than a 1-week response time, so balance the need for uptime with the associated costs.
Finally, monitoring solutions are key to keeping the system in top condition. A good monitoring system can alert you to equipment issues before they result in failure, allowing for proactive maintenance. Discuss with your vendor the availability of 24/7 support versus business-hour-only support, as this will impact both costs and response times. Proper planning for maintenance and support will extend the life and effectiveness of your LPR system.

7. Is the LPR Vendor’s System Integrable with Existing Infrastructure?
When selecting an LPR system, integration with existing hardware and infrastructure is key to reducing upfront costs and total cost of ownership. If your organization already has a camera network, servers, or networking equipment in place, reusing these assets can significantly lower expenses. However, you need to assess whether the current hardware is compatible with the new LPR system or if an upgrade is required to ensure long-term viability.
For integration, check whether the LPR solution offers APIs and can link with other security tools such as access control systems or monitoring software. The system should ideally be flexible enough to work with off-the-shelf cameras or proprietary hardware, depending on your setup. Additionally, you must consider whether the system requires CPUs or GPUs for processing, as this can impact both performance and cost, with GPUs typically offering better video and image processing capabilities, but at higher costs.
Connectivity and power requirements are also critical factors. Decide whether the system will run on wired or wireless services and ensure that the network can handle the increased load if additional cameras are added. If some of your cameras are going to be off-grid, such as running on solar power, or in areas with a fluctuating power supply, e.g. on light poles that are only powered at night, plan for sufficient battery storage to maintain functionality during periods of no grid power, which can add complexity and cost.
8. What is the Total Cost of Ownership of the LPR system?
When evaluating the total cost of ownership (TCO) for an LPR system, it's important to consider all phases of the project. First, there are upfront costs, which typically include installation, hardware, and software fees. The planning phase can also incur expenses, especially if the vendor charges for detailed project scoping or custom requirements. Make sure you have a clear understanding of the project's scope to prevent surprises later on. Accurate planning is crucial to ensure smooth implementation and avoid costly errors.
Next, consider ongoing costs such as maintenance and support. Camera hardware, networking equipment, and storage solutions must be regularly maintained and refreshed to keep up with technology advancements. It’s also essential to account for installation and labor costs—especially in cases where cameras need to be mounted in challenging locations, requiring specialized equipment and coordination with local authorities.
Finally, software licensing models vary, so it’s crucial to ask whether the vendor offers perpetual licenses, annual renewals, or multi-year contracts. Be aware of potential increases in licensing fees at renewal, and factor this into your long-term cost analysis.
9. What’s the LPR Vendor's Reputation and Customer Feedback?
When evaluating an LPR vendor, their reputation and customer feedback are key factors to consider. Begin by investigating their industry reputation through online reviews, forums, and testimonials. Keep in mind that reviews found online tend to be either highly positive or highly negative, which may not offer a full picture. It’s useful to take online feedback with a grain of salt and use it as a general guideline rather than the final word on the vendor’s reliability.
To get a more comprehensive understanding, request references from the vendor. While they will naturally provide their best-case references, make sure to ask about long-term customer experiences, particularly those that have gone through contract renewals. This will give you insight into how well the vendor manages ongoing relationships and how responsive they are to customer needs over time.
It’s also worth asking to speak with clients who have experienced challenges with the vendor’s system or service. Knowing how the vendor handles disputes, resolves issues, and communicates during critical times can provide valuable insight into the health of the customer-vendor relationship. Finally, consider any mergers or acquisitions the vendor may have gone through, as these can sometimes affect the quality of support or service post-acquisition.
10. How Does the LPR Vendor Ensure Compliance with Legal and Regulatory Standards?
When evaluating LPR vendors, compliance with legal and regulatory standards is essential to ensure the system adheres to local and national laws. Start by confirming that the vendor complies with regulations like GDPR, CCPA, or other relevant data protection laws. This is critical to avoid legal complications, particularly when handling sensitive information, such as vehicle data, which is subject to strict privacy standards in many regions.
It's important to clearly communicate your retention and deletion policies. How long data is stored can expose you to legal risks. Longer retention periods increase the chances of privacy violations, unnecessary legal scrutiny, and costly demands for data extraction or audits. It's wise to keep data only as long as necessary to reduce exposure to these risks.
Additionally, you should understand where the data is stored, whether it's on-premise or in the cloud, and ensure that proper encryption measures are in place to safeguard from potential breaches or misuse.
Lastly, consider the broader regulatory environment, especially at the state and federal levels, since laws governing LPR usage can vary significantly. Ensuring compliance from the start can help you avoid unexpected legal hurdles during the implementation phase, saving you from costly delays or rework later on.
