License Plate Recognition: Best & Most Portable LPR System

License Plate Recognition (LPR), also known as Automatic Number Plate Recognition (ANPR), is an important step in vehicle checkpoint security. The best LPR systems have the capability to accommodate vehicles of all sizes and moving at various speeds, while still maintaining portability in cases where rapid deployment is necessary.

What makes the best LPR system?

Below Are 4 Key LPR Capabilities:

Front and Rear Captures: An LPR system should have the ability to automatically capture both front and rear plates. Regulations differ from state to state and country to country. To ensure all information is captured for review, images of the front and rear number plates should be captured and documented.

Front and Rear LPR / ANPR

Rapid Deployment: To increase the operator’s mobility and maintain a small footprint, an LPR system should have the ability to be deployed in minutes. The best example of this key capability is the LowCam under vehicle inspection system’s LPR.

The LowCam includes an embedded LPR system within its inspection ramp and requires no additional equipment, such as external cameras or camera mounts, for set up. As a result, the entire system can be deployed in three minutes or less with no additional calibrations. With no calibration required in set up, deployment is fast and effortless.

Direct Alignment: To capture the best possible images of front and rear license plates, cameras must have precise alignment to accommodate vehicles of any size and height. Some LPR systems require calibration to accommodate different vehicle heights.

With the LowCam under vehicle surveillance system, no calibration is needed. This is accomplished by advanced LEDDAR sensor capabilities that detect a vehicle’s speed and height and direct the cameras to capture plates at the most optimal moment. Direct alignment ensures a higher quality image and increases capture confidence rate.

Reporting: The purpose of an LPR system is to capture and monitor vehicles that pass through a checkpoint. Reasons to capture this information can include checking for vehicles that are on BOLO lists as well as monitoring vehicles who have passed through the checkpoint previously. An efficient LPR system should have the ability to quickly and easily provide a history report of vehicles that have been captured by the system.

LPR Recognition Comparison

The LowCam under vehicle inspection system collects and recalls license plate numbers to provide side-by-side comparisons of a vehicle’s undercarriage. The first time a vehicle is scanned, a “master” image is saved and associated with the captured license plate number. When the vehicle returns, the original “master” image can be recalled so that a side-by-side comparison can be analyzed against the most recent scan image.

An automatic license plate recognition system is a valuable tool for a variety of different checkpoints.

Local and state law enforcement, border controls, and military installations are just a few who use LPR systems to check for vehicles on watch lists and compare returning vehicles for undercarriage discrepancies.

Advanced Detection’s LowCam under vehicle inspection systems have the option to be equipped with the most advanced LPR / ANPR system on the market. With the unique feature of being embedded within the inspection ramp, there is no additional set up or calibrations required. This vehicle surveillance and LPR system combination is the most portable and effective method of capturing license plate numbers for an efficient vehicle checkpoint.
