What is an LPR camera?

A license plate recognition (LPR) camera scans a vehicle’s license plate to determine whether the driver is authorized to enter the property. The camera is part of a larger LPR system, which reads the plate number and checks it against the system’s database. If the plate is registered in the system, access will be granted.

These specialized cameras are incredibly precise at capturing and digitizing images from license plates with about 99% accuracy. They also read plates in as little as just 20 milliseconds. As a result, this makes them an effective vehicle access control solution.

Additionally, this technology is commonly used to control access to gated communities and other non-residential properties. In these scenarios, the property’s gate automatically opens once the system recognizes and approves a registered vehicle’s license plate.

However, license plate reader cameras are also commonly used by law enforcement as traffic light cameras to get a clear image of a car’s license plate after they’ve sped or run a red light.

In addition to access control and traffic light cameras, LPR cameras are used in a variety of ways, such as:

  • Ticketless parking systems
  • Modern toll billing systems
  • Other law enforcement uses

What is the difference between LPR and ANPR?

LPR (license plate recognition) and ANPR (automatic number plate recognition) mean basically the same thing, so it’s common to see these terms used interchangeably.

As a result, the difference between these two acronyms often comes down to specific providers, how they brand and characterize their products and the type of services they provide.


How do LPR cameras work?

ANPR camera systems use a specialized camera to scan images of license plates. Once this image is generated, the camera feeds this data to software that identifies the characters of the plate before converting it into an electronic format.

After converting the data, the system compares it against its database of registered users. If the license plate matches a registered user, they’ll be granted access.

What should I look for in an LPR camera system?

There are several qualities to look for when choosing the best LPR camera for your building.

Qualities to consider:

  • Zoom or bullet cameras. Zoom cameras (also known as bullet cameras)  zoom in on license plates and generate clear images with incredible precision. As a result, they provide the most accurate reading of license plates.
  • Multi-camera playback. Multiple cameras capture valuable contextual images of the vehicles that enter your property. As a result, this significantly reduces any errors when granting access to users. For best results, install several cameras to accurately track and monitor the cars that enter the premises.
  • API integration. API integration exports the data from your LPR camera to other databases. This allows you to connect your LPR system with other gate access control and proptech solutions.
  • Searchable logs. Choose an LPR camera software that offers searchable logs that allow you to search the database for suspicious license plates. Additionally, this software makes it easy to access video footage of every car that enters your property.
  • Fuzzy matching. Fuzzy matching or fuzzy logic is a type of AI that’s designed to provide a more accurate reading of license plates. For instance, if your system registers an O character as a 0, the system is programmed to recognize this error. What’s more, these systems give administrators the ability to access logs and correct any license plate-capturing errors so that the plate is read correctly.

How much does an LPR camera cost?

The cost of an LPR security camera can vary depending on the quality of the camera and the range of features it offers. CCTV cameras typically cost $300 – $500 on the lower end. However, they can cost upwards of $1,000 – $5,000 per camera depending on the type of system used.


5 ways to use LPR cameras

Plate recognition technology is used in a variety of ways to automatically grant access to residents, staff, and visitors.

Here are a few use cases for LPR cameras for different kinds of properties:

  1. Apartments and gated communities
  2. Commercial buildings and offices
  3. Student housing
  4. Parking garages
  5. Coworking spaces


1. Apartments and gated communities

Plate recognition cameras are a convenient access control solution for residential properties because they allow for seamless visitor management.

Residents manage access for their guests by registering recurring visitors’ license plates to quickly authorize them for entry. This results in seamless visitor management since the camera can scan the guest’s license plate and allow them to enter.

This technology can be used to let in visitors like family, friends, dog walkers, and professional cleaners.

2. Commercial buildings and offices

Automatic plate recognition cameras quickly grant access to staff, visitors, and any authorized user that’s been registered in the system for seamless access control. A CCTV system is great for parking structures at commercial properties. This streamlines access by allowing administrators to monitor who’s entering the property and when.


3. Student housing

One of the most common security concerns at college campuses and universities is the ability to monitor and manage access to students’ and staffs’ vehicles. An LPR camera allows students, faculty, and staff to securely access parking areas or gated neighborhoods on college campuses with ease.

To use an LPR camera effectively, simply register every student, faculty member, and staff’s vehicles at orientation or at the beginning of each semester.


4. Parking garages

Specialized CCTV camera systems are an ideal parking access control solution because they reduce the risk of unauthorized vehicles entering your parking facilities. Consider monetizing your parking garage by allowing users to pay to temporarily register their license plate in the system, or limit access to tenants and staff at your building.

5. Coworking spaces

Automatic plate recognition cameras are an effective way to implement physical access control at your shared coworking space’s parking garage or lot. Workers who are registered at your building can enroll their license plates into your LPR system for quick and easy access to your office’s parking structure.


Challenges of LPR cameras

Plate recognition cameras are a decent option for vehicle access control, but they come with a few challenges to consider before implementing one at your property.

Here are some common drawbacks of LPR cameras:

  • High cost. High-quality LPR camera systems can cost tens of thousands of dollars depending on the number of cameras you install. This cost skyrockets, even more, depending on the kind of software your system uses.
  • Limited software compatibility. CCTV camera systems are not as effective when they don’t integrate well with other access systems and proptech.
  • Additional hardware. Most LPR systems require additional hardware to work effectively. This often leads to a time-consuming and expensive installation process. What’s more, LPR cameras may require an LPR-dedicated NVR (network video recorder) that serves as the main hub for device recording and data storage.
  • Limited users. Some LPR cameras only register a limited number of users, which isn’t ideal for large businesses or multifamily apartment buildings.
  • Requires tenants to register visitors. Some systems only work for visitor access if the guest has been pre-registered before arriving. If the guest hasn’t been registered, you’ll need a separate system in place to allow them to request property access.
  • Unclear license plates. The camera may not get a clear reading if a vehicle’s license plate is covered in snow or has visible damage. As a result, a security officer or staff member may have to manually enter the license plate number to grant access.

Alternatives to LPR cameras

These specialized cameras have several drawbacks, but the expensive cost of purchasing and maintaining them is one of the most pressing concerns. Luckily, there are a couple of viable alternatives that can streamline vehicle access at your building.

Video intercoms and vehicle readers with windshield stickers are both great options to consider.


Video intercoms

A video intercom allows staff and residents to launch two-way video calls with visitors so they can verify their identity before granting them access.

Users can also issue temporary virtual keys to guests so they can quickly and easily access the building. Additionally, these virtual keys can be set to expire after one use, or you can set them to function only during specific days or times. As a result, you don’t have to worry about visitors continuing to use their virtual keys past their expiration.

With both of these visitor access methods available, residents don’t have to pre-register their visitors or know their guest’s license plate number.

What’s more, ButterflyMX video intercoms allow users to open doors and gates with just a swipe of their smartphones. Additionally, our intercom accepts 6-digit access PINs if a staff member or resident’s phone dies.

Vehicle readers and windshield stickers

Vehicle readers and windshield stickers are an affordable alternative to LPR cameras for tenant access because the stickers are cheap to buy and can even be moved after you place them on a vehicle.

A vehicle tag reading system works by scanning the sticker when someone pulls up to your gated entrance. Best of all, the driver doesn’t have to fumble for their key fob or roll down their window to gain access.



  • Number plate recognition cameras offer a simple and secure way to control vehicle access.
  • License plate recognition camera systems are usually expensive and may not integrate well with other access control or proptech solutions.
  • Video intercoms and vehicle readers with windshield stickers offer a convenient solution for vehicle access control at your multifamily building, commercial office, parking structure, or student housing facility.
