LPR: The Latest in Frictionless and Hands-Free Vehicle Access Control
Overview: What is LPR?
In an LPR application, the vehicle’s license plate serves as its identification credential, eliminating the need to administer any additional credentials or mount any tags to the vehicle. An LPR camera’s job is to capture an image of the vehicle’s license plate, and use the plate image to accurately process and identify the license plate characters. The camera can then forward the plate ID information to an access or revenue system.
How does it work?
To learn more about how TagMaster NA’s intelligent LPR cameras identify and process license plate identification numbers, take a look at our post “Any Plate from Any State.”
In short, TagMaster NA’s intelligent LPR cameras use vehicle motion detection (VMD) and plate localization to identify a license plate and record an image of the plate. The camera then uses its algorithms (such as optical character recognition, regional syntax, character segmentation, and de-skewing) and machine-based learning capabilities to accurately process each of the characters in the plate capture.
Depending on the camera’s capabilities, credential validation can either happen onboard (as with the CT-45), or information can be sent to an access or revenue system via TCP/IP/REST, or a Wiegand connection. The camera or the access or revenue system can validate credentials to grant or deny access, and the plate ID is logged along with the time it was captured and any additional information supported by the LPR software, such as vehicle type and color, driver name, driver category, alerts, etc.
Benefits of LPR for AVI
LPR offers numerous benefits for AVI applications. Below are a few of the reasons LPR is increasingly popular as a vehicle access control solution:
- Hands-free access: The vehicle’s license plate is automatically identified and processed by the LPR system, allowing authorized users to keep their hands on the steering wheel and their windows rolled up for convenient, hands-free access.
- Cost effective: With LPR, license plate validation happens quickly and automatically. No human intervention is necessary, making LPR a cost effective vehicle access control and management solution.
- Data collection: An LPR system improves visibility, logging every instance of access for a particular license plate credential, along with access time and any associated information supported by the LPR software, such as the name of the vehicle’s owner or the visitor category. This ability to easily record and report access data assists with streamlining oversight, process monitoring, revenue tracking and other important operations.
- Increased security: An LPR system can automatically verify credentials and deny access to unauthorized vehicles, protecting a facility against instances of unauthorized vehicle access. And a vehicle’s license plate can be captured by an LPR camera even if the license plate does not exist in the database, providing additional security when attempts to gain unauthorized access are recorded.
- Increased safety: In addition to added convenience, hands-free access also increases drivers’ safety by allowing them to keep their windows rolled up when gaining access to a parking facility late at night. This increases driver focus and decreases instances of collisions with other vehicles or equipment.
