L-3’s AlertVu: The Next Generation in ALPR

Written by Jennifer Gavigan

L-3’s AlertVU™ represents the next generation of Automated License Plate Recognition (ALPR) for law enforcement. It utilizes state-of-the-art multi-process plate recognition technology that enables multiple “plate image streams” to be processed through multiple recognition engines concurrently. This means many more “views” of the plate and many diverse recognition techniques being applied resulting in a quantum improvement in recognition performance.

With AlertVU, thousands of license plates can be processed, improving an agency’s efficiency and safety. Constant scanning reveals plates that are “wanted” even when the vehicles have done nothing to draw attention to themselves. In addition, officers can utilize “Intelligent Gathering” to post process data and identify suspicious trends and patterns, allowing for clearer situational awareness. L-3’s flexible and scalable system allows agencies to customize the solution to their needs.

Features & Functions

L-3 provides a comprehensive and functional back office solution. All the ALPR units can be aggregated, searched and historically analyzed. All data automatically gets transferred to and from the car wirelessly without manual intervention. In addition, the ability to use both infrared and color cameras allows agencies to have solutions for various mission applications.

AlertVu can be integrated into the L-3 Communications In-Car Video (ICV) solution such that the ALPR can trigger the ICV system into pre-event record, and it can also utilize the ICV GPS to record the vehicle location with each plate read. Another plus: AlertVu operates with either the L-3 Mobile Data Computer or many existing in-car computer solutions, which means agencies won’t have to scrap existing computers to utilize this technology.

AlertVu’s full integration with existing vehicle components simplifies implementation and reduces costs. Additional benefits include multiple integrated recognition engines and parallel processing; full-featured back office with automated wireless car; and communication. Fleet-wide data aggregation/analysis allows for simple agency-wide utilization.

Implementation

The L-3 AlertVU system can be a “standalone” solution, or it can be fully integrated with existing in-vehicle equipment. When a pre-existing L-3 in-car camera system is present, then that wireless communication solution and DES server can be repurposed. That means no new wireless infrastructure is required. Agencies get seamless communication and server-based data access, consolidation and analysis without new equipment or the typical installation headaches.

AlertVu Solutions

Rather than forcing law enforcement to accommodate to a technology, L-3 has created a solution that makes technology work for law enforcement. There are several packages targeted at addressing specific ALPR focus areas for an agency.

AlertVu Basic is a small, internally mounted, front-facing color camera that results in a cost-effective implementation configuration for the agency that is attempting to maximize the number of ALPR-equipped cars. The internal front camera can be easily repositioned for speed enforcement, opposing or following traffic or parking areas.

The AlertVu Parking cameras are twin low-profile side cameras purpose-built for the rapid scanning of parking areas. They contain active emitters that automatically enable as required depending on the light level and are positioned to quickly read license plates in a targeted parking lot.

By combining the front-facing color camera with the parking lot patrol configuration and a low-profile IR camera system, AlertVU Custom allows for a very versatile package that can easily read plates from multiple sectors and environments concurrently. Covert camera options are available for clandestine surveillance.

All of the standard packages can be modified to optimize the performance for a particular agency’s ALPR needs. Up to eight cameras can be supported including multiple IR systems. For most applications, AlertVU can operate on the existing mobile data computer without compromising its performance. But for those with old MDCs, L-3 has a self- contained and cost-effective CPU.

AlertVu IR Parking Camera

L-3’s AlertVU IR Parking Camera features rapid scanning of cars parked in parking lots. The device itself is small and unobtrusive (with invisible IR illuminator). Mounting is available either by the light bar or on the trunk lid. These cameras are built for the rapid scanning of parking areas. They contain active emitters that automatically enable as required depending on the light level and are positioned to quickly read license plates in the targeted parking lot. The side-facing hybrid IR/Color solution is dedicated to quickly and easily read license plates in both daylight and darkness.

Benefits of the AlertVu External Dual IR/Color Camera include daytime and dark night operation; view of receding traffic (rear plates); and they are good for night ALPR stakeout.

The External Dual IR/Color Camera is a fixed position, externally mounted option providing extended-range forward and rear visibility with superior performance day or night. An extended-range, dual IR camera solution in a compact weatherproof package provides superior performance in all kinds of climates and environments.

The AlertVu Front Color Camera provides multiple forward-facing “target areas of interest” within the headlight zone. Views include approaching traffic (front plates), overtaking traffic (rear plates) and parallel parked cars. A small, internally mounted, front-facing color camera results in a cost-effective implementation configuration for the agency that is attempting to maximize the number of ALPR-equipped cars. The internal front camera can be easily repositioned for speed enforcement, opposing or following traffic or parking areas.

Woodbridge, N.J.

Woodbridge is a township in Middlesex County, N.J. As of 2010, Woodbridge’s population was 18,883 people. Since 2000, it has had a population growth of 3.14 percent.

Chief William Trenery’s mission in improving the relationship between the police and the citizens they serve facilitates the cooperation vital to the department’s ability to achieve its goals. Part of that mission involves the use of L-3’s AlertVu ALPR solution. According to Police Systems Administrator Andrew Curry, AlertVu is another tool his officers can use to make their jobs easier. “We like the system; it works well for us.”
