Welcome to ALPR 101

Automated License Plate Recognition (ALPR) is a technology that uses optical character recognition (OCR) to automatically read license plate characters.

ALPR for Security industry

Security and Safety

Automatic license plate recognition (ALPR) is becoming an increasingly practical security solution for Cities, Hospitals, Private Businesses (campuses), and Colleges

As a result, one of the main ALPR trends is the migration from primarily mobile to predominantly fixed-location systems. Such systems provide the comprehensive, effective coverage that mobile systems could not achieve and yield significant savings as well. Furthermore, they are easily scalable, as the technology can be connected to new cameras almost instantly once they are installed. The most effective ALPR is also open architecture, which enables it to interface with the wide variety of video management systems (VMS)



ALPR – enables access control systems to use vehicle license plates to grant or deny access, and to efficiently control vehicle flow coming in and out of the monitored facility.

Automatic entry can be given via a gate or barrier if a recognised “white list” vehicle is identified by the system, whilst any unrecognised vehicle can be denied access to your premises.

Not only does this provide extra security to your site, it also makes visitor management for your security personnel easier to manage. Furthermore, visitors can be sent a message on arrival giving your guests a personalised welcome.
ALPR (Automatic License Plate Recognition) camera system integrated with Access Control System offers the most effective vehicle access control solution. By utilizing a vehicle’s license plate as a user credential, the system requires no additional equipment such as RFID chips and barcodes – making this the least expensive and most reliable system on the market. Using the license plate as the credential requires no interaction from the driver, virtually eliminating wait times and bottlenecks caused by the need to stop and show or swipe an ID badge.

In Sum, ALPR camera system creates an efficient, accurate and reliable platform, enabling Access Control operations management to automatically grant or deny access, recognize and evaluate vehicle patterns, detect suspicious behavior and run faster forensics.



Ticketless applications use ALPR as the sole means of linking the entry and exit movements of vehicles with their corresponding parking fee.

When a vehicle enters the parking lot, the ALPR units capture its license plate and store it in the parking management system database until the vehicle leaves. Before returning to the vehicle,
the driver has to go to a pay station, type in the license plate and make the payment. When he/she drives to the exit, the boom gate will automatically open as the license plate of the vehicle has been recognized and the system has checked that the correct payment has been made.
Ticketless parking eliminates the need for printed paper tickets, contributes to better traffic flow at entrances and exits, and enhances the user experience.



Electronic Toll Collection (ETC) is a technology that allows for electronic payment of tolls. An ETC system, supported by ALPR -Automatic License Plate Recognition Camera System, is able to determine if a car is registered in a toll payment program, alerts enforcers of toll payment violations, and debits the participating account. With ETC, these transactions can be performed while vehicles travel at near highway cruising speed.

Electronic toll systems, like conventional toll systems, generate funds for building and maintaining roads. They also offer a number of additional advantages. For example, they improve traffic flow by significantly reducing delays at the toll booth. In one hour, an electronic system allows 500 vehicles per lane to pass (1,800 in free flow) compared with just 200 for conventional systems. In addition, the transaction is much simpler for the user because it is entirely automatic. Electronic toll collection systems used today are very reliable: they have an error rate of less than 0.01%. By making traffic more fluid and avoiding bottlenecks, electronic toll collection helps reduce the number of accidents and improves the environmental impact. It also eliminates risks inherent in transferring funds because no cash is involved.
In addition to ETC, Automatic License Plate Recognition (ALPR), system is very much useful in applications like, automated traffic surveillance and tracking system, automation of gas stations, travelling time monitoring, and much more.
