Leonardo Selects Perle PoE Switches to Fuel ALPR Cameras

By CIOReview | Tuesday, February 16, 2021

IDS Industrial Switches offers up to 30 Watts PoE to Elsag Fixed Plate Hunter ALPR cameras mounted along highways, bridges, tunnels, and overpasses.

FREMONT, CA: Automatic License Plate Recognition (ALPR) systems are leveraged to help law enforcement, toll collection, and traffic data analysis. By mounting cameras along highways, tunnels, bridges, and overpasses, vehicle speed and license plates can be captured to automatically identify suspect vehicles or validate vehicles on roadways as part of an HOV lane or tolling program. The data can also be leveraged to analyze traffic statistics, identify traffic patterns, or identify real-time anomalies, like traffic jams, crashes, and other dangerous occurrences.

When Leonardo developed the Elsag Fixed Plate Hunter ALPR System, they had to ensure it would provide reliable and constant operation but be customizable enough to meet unique deployment requirements set by different customers and agencies. The ALPR system comprises innovative digital cameras connected to a Field Control Unit. Inside the FCU, a power switch would be required to manage all of the data transmission. Leonardo had five main needs for the switch. They can provide up to 30 watts PoE to the attached cameras, and they have at least three ethernet ports, they have output connections for Twisted-Pair Copper or SFP Fiber, can be rugged enough to operate in -40°F to +165°F, and can be small enough to fit inside the FCU.

Perle’s range of IDS PoE Industrial Switches fit the bill. They are classified as Layer 2 Power Sourcing Equipment and fully compliant to IEEE 802.3 to ensure reliable PoE to the attached cameras. Depending on the unique deployment requirement, Leonardo can choose the variant with the necessary number of copper ports and fiber ports required for each customer. Every component utilized in designing these compact switches is fully tested and rated to operate from -40°F to +165°F. The Elsag Fixed Plate Hunter ALPR System reads plates day or night, in all climatic conditions, and from all 50 U.S. states and most foreign countries.
