Can parking lot cameras read license plates?

Yes, but not all cameras can read crystal-clear license plates! 

Not all parking lot cameras are created equal; if your current system can’t capture license plates, consider upgrading. Blurry footage. Manual logs. Missed details. That’s not security.

It’s not offering the protection your business needs. In this blog, we’ll explore which cameras can read license plates and why it matters when managing security, access, and efficiency of a parking lot.

How do parking lot cameras read license plates?

Modern parking lot cameras aren’t just passive observers. They utilize smart sensors, motion tracking, and, in some cases, AI-powered analytics to monitor vehicles and foot traffic in real time. 

When equipped with License Plate Recognition (LPR) technology, these cameras can automatically read vehicle license plates. Here is an image depicting what it captures:

What is LPR technology?

LPR utilizes specialized optics, infrared lighting, and image recognition software to detect and interpret the numbers or letters on license plates in real-time. 

This tech is commonly used in smart parking lot systems, gated communities, and commercial properties where vehicle identification is key to access control, time tracking, and security enforcement.

The LPR technology is also referred to as ALPR (Automatic License Plate Recognition) or ANPR (Advanced License Plate Recognition). 

In some European countries, it is also referred to as Automatic Number Plate Recognition.

These special LPR cameras can read license plates using cameras, software, and Optical Character Recognition (OCR) to capture, process, and identify the characters on license plates.

Whether it’s day or night and in any weather. The LPR cameras can:

• Capture. The camera captures the plate of every vehicle entering the lot.
• Identify. The system identifies the vehicle’s registration number in real-time.
• Log. Each plate is logged with a timestamp for future reference.

Surveillance cameras—whether dome or bullet style—can capture license plates. However, for fast-moving vehicles or low-light conditions, you’ll need a camera specifically equipped with License Plate Recognition (LPR) technology for accurate results.

The difference between an ordinary CCTV camera and an LPR camera:

The image above illustrates the stark contrast between blurry footage from standard cameras and the crisp, high-contrast images captured by LPR systems when tracking moving license plates.

Unlike regular security cameras that simply record video, LPR (or ANPR) systems are designed to recognize, analyze, and trigger automated actions based on what they detect.

Built for precision and intelligence, they’re ideal for environments that demand automation, accuracy, and real-time decision-making.

How can you determine if the parking lot has a camera?

To protect your vehicle and its belongings, it’s essential to ensure that the parking lot you park in is equipped with surveillance cameras. Here are a few tips to keep in mind while searching.

• Look for visible cameras mounted on light poles or building walls.
• Check for dome cameras on ceilings or canopies near entrances.
• Notice warning signs saying “Area Under Surveillance” or “CCTV in Use”.
• Spot small boxes or sensor-like devices attached to poles (often used for cameras).
• Look for blinking lights, especially at night, on mounted devices.
• Ask security personnel or staff if the lot is monitored.
• Check for security booths or patrol vehicles in the vicinity. Watch for solar-powered units or sometimes mobile units.
• Look for floodlights that are mounted and combined with camera systems.
• Notice if there are speakers or intercoms; sometimes they are also paired with CCTV cameras.

A parking lot without cameras often lacks visible surveillance signs or equipment, such as cameras mounted on poles or buildings. 

Blind spots and dimly lit areas can indicate a lack of security, while a shortage of security guards or patrols further suggests inadequate monitoring. Suppose there is no emergency call box or intercom, and the lot shows signs of vandalism or neglect.

In that case, it is a clear indication that security is lacking, putting both property and personal safety at risk. Here’s why you need a surveillance camera in your lot:

Why do you need an LPR camera in parking lots?

• Protect against theft.
• Reduce accidents and collisions.
• Deter mischievous behavior.
• Automate entry and exit records.
• Track how long vehicles stay.
• Improve occupancy detection accuracy.
• Get better insights and analysis.

Protect against theft:

Parking lots are vast spaces, often home to thousands of cars spread across multiple aisles, day in and day out. 

With so much activity, theft is always a looming threat. People often leave valuable items in their cars, assuming that a camera in the parking lot will provide the security they need to keep their belongings safe. 

But the reality is, that’s not always the case. Inadequate or poorly placed surveillance can leave your property vulnerable. Here’s a look at what’s at risk when proper security is missing:

And if your lot is among the highest-ranking states, your vehicle could very well become a target for criminals.

LPR cameras in garages and lots enhance security by providing real-time monitoring of vehicle movements, automatically logging entry and exit times, and offering valuable footage in case of security incidents.

Reduce accidents and collisions:

Parking lot cameras play a crucial role in monitoring the speed of vehicles, which is especially important because motor vehicle accidents can happen at any speed. 

What many don’t realize is that some of the most frequent crashes occur at speeds of less than 40 mph. Surprisingly, these low-speed collisions often result in the highest number of injuries.

A report on speeding and traffic fatalities in the U.S. for 2022 revealed that speeding was a factor in 29% of all traffic fatalities that year. This highlights the significance of accurately tracking vehicle speeds, even in parking lots, to prevent accidents and improve safety.

Deter mischievous behavior:

And it’s not just theft, you need cameras in the parking lot to deter and detect individuals involved in many mischievous activities, such as follows:

• Hit-and-run accidents. • Keying or scratching cars. • Breaking windows to steal valuables. • Spray-painting graffiti on walls or vehicles. • Faking accidents for insurance scams. • Dumping trash or hazardous materials. • Vandalizing security equipment (like cameras). • Slashing tires or breaking into parked vehicles.

• Assaulting individuals in isolated areas. • Street racing or reckless driving through lots. • Loitering and harassing customers or employees. • Drug deals or illegal exchanges. • Trespassing after business hours. • Shoplifters escaping through the parking areas. • Flash mob-style thefts or coordinated property damage.

And the list can go on! But it’s not that simple. If incidents happen in your parking lot and you don’t have proper surveillance, your company could face lawsuits for negligence. Victims might sue for damages, injuries, or losses, claiming a lack of security. And above all, your brand reputation could take a significant hit.

Automate entry and exit records:

Manual entry can lead to inaccuracies and delays in tracking vehicles, causing inefficiencies in parking lot operations. With LPR cameras, automated entry and exit logs are captured in real-time, ensuring accurate and efficient tracking of vehicles without human intervention.

During incidents, LPR technology enables instant vehicle lookups, significantly improving response times. Additionally, LPR systems remove the need for keycards or tags, offering seamless access control by automatically identifying vehicles as they enter and exit.

Track how long vehicles stay:

While a modest lot of 15–20 spaces might withstand manual oversight, the complexity of a three-tier facility serving over 400 vehicles demands an automated regimen of entry-time logging, precise dwell-time calculation, and enforced exit deadlines. 

Critically, real-world deployments demonstrate that such innovative parking systems can reduce driver search time by up to 43%, alleviate urban traffic congestion by 30%, and cut per-vehicle CO₂ emissions by 40% PatentPC. 

Furthermore, case studies reveal that these investments pay dividends remarkably quickly, with return on investment realized in under two months collectiveingenuity.norda.com.

Without this level of automation and precise time tracking, large-scale parking operations face ongoing congestion, lost revenue, and serious compliance risks.

Improve occupancy detection accuracy:

Studies show that dwell times in authorized parking bays hover around 15 minutes, while unauthorized curb and travel lane parking average under 5 minutes, yielding an overall peak dwell time of approximately 10 minutes across both on- and off-street spaces.

Over 30% of drivers spend 6–8 minutes circling, and up to 40% of that gridlock is self-inflicted by overstayers. 

The solution? Dynamic, real-time parking lot alerts trim occupancy by 5.6% and slash search times by 12.5%—freeing up space, cutting emissions, and supercharging revenue in one clean sweep.

Get better insights and analysis:

Parking lot cameras don’t just pick out license plates and store them in a database. Smart parking lot cameras are capable of analyzing. It means smart cameras can process and analyze footage in real-time using built-in AI or computer vision algorithms.

 Powered by AI and trained on context-rich data, they extract meaning from motion:

• Know what’s moving. Human, vehicle, or animal—smart cameras don’t guess. They classify with precision, even in complex scenes.
• Read the road. License plates, vehicle types, color recognition—they turn traffic into structured data.
• Spot the outliers. Loitering in restricted zones? Missing safety gear? Suspicious movement? They catch what people miss.
• Measure presence. How long someone stays, when they arrive, whether they’re supposed to be there—it’s all time-stamped and tracked.
• Track the trail. Whether it’s a person walking or a bag left behind, smart cameras follow the story across time and space.

It’s not just surveillance; its situational awareness. Let’s have a look at how effective LPR cameras really are:

How accurate are parking lot cameras?

When set up correctly, License Plate Recognition (LPR) systems can achieve impressive accuracy rates of 95–98%, even with fast-moving vehicles or challenging nighttime conditions.

However, achieving this level of performance depends heavily on factors like camera placement, angle, lighting conditions, and the quality of the LPR software used.

Strategically placing two cameras — one capturing the front and the other the rear of vehicles — has proven highly effective. If one angle misses the license plate due to overspeeding or low light, the second camera often succeeds, significantly improving capture rates.

Further supporting this, a study presented at the 5th International Conference on Computer Science and Computational Intelligence found that smart IP cameras, when combined with deep learning models, can detect real-time parking availability with up to 93.15% accuracy and an ultra-fast 0.5-second response time per space — even under diverse conditions like bright sunlight, rain, and low lighting.

Case study:

Now let’s talk about a parking lot where CCTV surveillance cameras played a major role in catching thieves.

Security camera placement guidelines: Where to place them

How to choose the right LPR system:

Look for solutions with:

Real-time alerts:

When someone parks in a reserved spot, you need to know right away. Or you risk frustrated customers and lost fees. However, too many false alarms mean that real problems get ignored, and vague alerts leave your team unsure of what to do next.

Switching between half a dozen apps just to figure out where the issue is wastes precious minutes. CCTV surveillance cameras that can read license plates issue parking lot timers so you have complete control.

Cloud-based plate logs:

Cloud-based plate logging provides instant clarity on who came, when, and where. Slow, timeout-prone portals turn every lookup into a scramble, eroding your ability to respond to incidents or disputes in real time. The most significant advantage is that sensitive data is safe from unauthorized access.

Parking lot cameras integration with gate/barrier systems:

Integrating cameras with gate and barrier systems transforms parking lot management into a seamless, secure operation. Real-time video validation and automated vehicle access using license plate recognition or credentials streamline entry while minimizing human error.

This smart integration not only heightens security but also keeps traffic flowing smoothly, reducing congestion and improving user experience.

Mobile access for monitoring:

With mobile access, parking lot surveillance is no longer confined to a control room. Secure apps enable you to monitor live feeds, review incidents, and receive real-time alerts from anywhere.

Whether you’re across town or across the country, you stay in full control of your site’s security, responding faster and staying ahead of potential threats.

How to make parking lot cameras even more effective?

The answer is Remote Video Monitoring!

Suppose you own a parking garage, or you want to secure the parking lot of a multi-family residential complex or a shopping mall. In that case, integrating your CCTV cameras with remote video monitoring can offer proactive detection and swift action by trained operators.

They offer a suite of advanced analytics to detect intrusions, tailgating, loitering, and license plate recognition, securing your lot at the perimeter and from the inside.

As soon as the alarm is triggered, trained security operators watch live feeds in real-time, an action in accordance with the preset Standard Operating Procedures (SOPs).
