Korean Tunnel’s License Plate Recognition Program Uses Arecont Vision Technology

Recognizing the license plate numbers of cars traveling at high speeds through a dimly lit tunnel is oftentimes viewed as a highly challenging surveillance application.

But local law enforcement and traffic authority of a recently constructed motor vehicle tunnel in Korea have turned to the AV3130 MegaVideo solution from Arecont Vision.

The system was designed by local distributor, ViewRun, a Korean company experienced in machine vision and surveillance, and was installed by its integrator, Korea Image Systems Co. Ltd. The high resolution megapixel surveillance cameras from Arecont Vision were installed to capture the license numbers of cars that break the tunnel's traffic lights.

The Korean tunnel application uses Arecont Vision's dual-sensor AV3130 3/1.3 megapixel (3 megapixel in color mode, 1.3 megapixel in black and white mode) full motion progressive scan IP cameras providing up to 15 frames per second in color, or day mode and 30 frames per second in black-and-white or night mode.

Each camera contains a massively-parallel MegaVideo image processor chip that is capable of sustaining more than 6 billion operations per second.

ViewRun selected Arecont Vision cameras because of low-light performance and the full motion progressive scan capabilities.

The tunnel system also uses Arecont Vision's AV100 network video recorder software and the LuxRiot NVR video management software provided by A&H Software House, Inc., an Arecont Vision technology partner. The system sends video images along a 100 base T Internet connection.
