Using technology to help both the user and the company deploying is nothing new. In fact, it is the crux of why we develop new software and devices.
Security can often be seen as fairly one sided, but this is entirely inaccurate, it keeps everyone safer and keeps a more secure environment.
Automatic Number Plate Recognition (ANPR) is a form of car management technology that can be part of a wider parking management system that is designed to help oversee parking in a location.
In this guide, we will be looking at ANPR camera technology, breaking it down into easy to understand areas and answering some ANPR FAQs. We will also be looking at the benefits of this technology and how it works.
In sum, we'll be covering:
ANPR or Automatic Number Plate Recognition is pretty much what it says on the tin. ANPR is a technology that reads number plates via a camera and transmits the data to the system.
Depending on the reader model, number plates can be read in a range of weather conditions and speeds up to, and above, 100 miles per hour.
This technology can be deployed anywhere you want to keep track of cars coming in and out of a location, but you have probably seen it utilised in car parks in various locations.
If you have ever been leaving a car park and go to put your ticket in the machine and the gate automatically goes up, this is ANPR. The machine has recognised your plate, acknowledging you have already paid and allowing you to exit quicker.
ANPR is referred to as different things around the world, one of the common other names is Automatic License Plate Recognition (ALPR) in the US and Canada, due to the plates on vehicles referred to as license plates, not number plates.
The ANPR systems are fairly easy to understand, but let us look at what makes up this technology and what is required for it to work.
To keep it simple, there are three major parts to an Automatic Number Plate Recognition system; cameras, gates and the database or software.
Obviously, this differs depending on how you apply your ANPR, a car park for instance tracks who has paid, a company car park would track employee plates.
Automatic License Plate Recognition cameras can be used in a wide variety of settings from car parks to company offices, to police vehicle checks, but how do they work?
ANPR technology basically reads a registration plate when the vehicle is within its scan radius and will either enter it into a database or scan it against the records.
This depends on where it is being deployed, a car park will scan new vehicles, whereas a company’s headquarters may only let pre-authorised vehicles in.
ANPR Systems can work in two different ways, to oversimplify, they can capture either:
Some of this technology uses Optical Character Recognition (OCR) which basically allows the cameras to digitally read and extract the alphanumeric characters from the digital footage.
ANPR software has to be able to recognise and correctly determine license plates from different regions and countries around the world, ANPR systems will typically have 7 algorithms embedded in the software to help read plates.
Automatic Number Plate Recognition technology has a wide variety of benefits that can be attributed to it, so we will be covering two core areas. Operational and User Benefits, so how it affects the end user and how it impacts your business.
These benefits will be fairly universal so they can be applied to most uses of an ANPR system and would affect most companies using them.
One of the major concerns companies have when deploying new technology or systems is the ease of installation or the ability to manage it post-implementation. ANPR systems are seen as an hands-off approach to vehicle access control.
ANPR technology is managed by a database that is typically very user friendly and designed to be used by any skill level, with simple settings and features to customise the experience.
Having an automated system gives you the flexibility to control and manage your locations around the clock. As opposed to a security team, a machine is cheaper and does not need to worry about shift times or breaks.
This gives you the option to have a 24/7 operation that is secure at any time. In addition, the majority, if not all, of ANPR systems are designed for any weather and lighting conditions so work whenever you need them to.
Higher end ANPR systems vary between 95-100% accuracy rate depending on which one you get, but will often be nearer the upper end of these percentages.
The only times the information may truly be skewed is when something is blocking the camera or the plate, such as debris, dirt, or dust.
ANPR for gate systems give you an added layer of location management and with this, an improved overall security infrastructure.
On certain systems, additional features range from a form of red flag list that tells you when a vehicle you have pre-flagged is scanned. This could be unauthorised vehicles or persistent criminals.
Finding ways to benefit your users is an additional benefit when installing a new security or management measure. Having an ANPR system allows for a smooth and easy user experience.
Let us put this into context, the gate may automatically recognise a car and let the driver out of a gate as they drive up, saving the user valuable time.
Normally, reluctance to embrace new technology stems from the time or effort it takes to learn how to use it. This is where Automatic Number Plate Recognition comes into its own, there is no learning curve for users, as the name suggests, it’s automatic.
When implementing new methods or procedures it is always important to consider the end user, in this case, the drivers. Choosing technology that benefits both you and them creates a much higher approval rate.
As a driver, we are frequently concerned about where we leave our vehicles and the security of an area we disembark our car. This acts as a form of deterrent for unauthorised people and vehicles.
Having an ANPR system that is linked to a gate means visitors and drivers can be more comfortable knowing only authorised vehicles and persons are allowed on the premises.
As we have alluded to above, the fact that ANPR is automated makes it useful for drivers and creates a seamless experience for them. Automation means that any time the driver needs to access a gate or area they can get in without human intervention.
This directly links to the operational benefit of not having to staff the gates around the clock and allows everyone access when they need it.
Automatic Number Plate Recognition (ANPR) technology is securing gate access across various industries.
Let's explore how different sectors are leveraging this innovative solution to enhance security, streamline operations, and improve user experience.
From bustling corporate campuses to high-traffic logistics centres, ANPR-based systems like Nedap's Lumo are optimising vehicle access control.
Key Benefits:
Potential Challenges:
Example: Nortech worker with a major logistics company to implement ANPR at their distribution centres, cutting average entry times from an average 2 minutes to just 15 seconds per vehicle.
ANPR technology is helping gated communities strike the perfect balance between tight security and resident convenience.
Key Benefits:
Potential Challenges:
Example: Nottingham Park Estate installed Nedap's ANPR Lumo, replacing the old vehicle tag system. The ANPR system was connected with Norpass to improve site security for residents, visitors and tradesmen.
Universities and schools are discovering the benefits of ANPR systems for managing campus parking and enhancing overall security.
Key Benefits:
Potential Challenges:
Example: Sleaford College implemented Nedap's ANPR system into their existing infrastructure to improve school perimeter security whilst also reducing congestion on-site from unauthorised vehicles.
As these examples demonstrate, ANPR for gates offers versatile solutions across various industries.
While the specific applications may differ, the core benefits of enhanced security, improved efficiency, and better user experience remain consistent.
As technology continues to evolve, we can expect even more innovative uses of ANPR in access control systems.
Are you considering implementing ANPR for your gates? The key is to assess your specific needs and challenges to determine how this powerful technology can best serve your organisation.
