A scheme has been developed in which Vialseg's red light application system uses high-resolution images taken by IP9171-HP cameras and custom-designed software delivers this image to Neural Labs LPR software to analyze traffic light status and vehicle position.

Prior to the project carried out by Vialseg, the use of traffic lights in Argentina depended on devices that operated on underground physical inductive ties and physically connected to the traffic light controller. This system suffered constant delays, preventing images of violations from being recorded due to street maintenance or disconnections with the same traffic lights.

Vialseg suggested combining two chambers and a license plate recognition solution (Lpr), so they combined forces with Selnet, local distributor of Vivotek, And Neural Labs, LPR software partner.

This company designed the system and software based on the technology provided by Vivotek and its H.265 box-type network camera 3 megapixels IP9171-HP (AB6117-HP). In a joint work with tuition recognition experts (Lpr), Neural Labs, Vialseg and its partners developed a scheme in which Vialseg's red light application system uses high-resolution images taken by IP9171-HP cameras (AB6117-HP). Custom-designed software delivers this image to Neural Labs LPR software to analyze traffic light status (red/yellow/green) and the position of vehicles allowing to detect when a vehicle does not respect the red light.

Traffic officials automatically receive all images for use as evidence in appropriate legal actions against violations.

blankRed light application systems are already used in the cities of Escóbar, tanned, Necochea and Colonel Pringles, all in the province of Buenos Aires, Argentina's largest size and population, and the system is expanding. Plans to continue the implementation of the system in the city of Buenos Aires and other major metropolises are underway, estimating more than a hundred systems to be installed this year.

Acting like the eyes of the system, Vivotek's IP9171-HP camera (AB6117-HP) it's an H.265 box-type network camera that delivers excellent quality images up to 30 fps with 3 provides accurate identification of plates under any conditions.

Features by which Vialseg chose this camera

  • Runner-like view. This feature allows you to capture panoramic images of the traffic light and intersection efficiently.
  • The day and night function and camera zoom allows you to identify the vehicle using LPR and infrared lighting to improve board reading under poor lighting conditions and at night.
    Remote back focus. Helps installers fine-tune it without the need for stairs or other lifting means.
  • The combination of WDR Pro technologies and Supreme Night Visibility (Snv) allows you to adjust and capture high-resolution images in both high-contrast lighting conditions, feature of a day with bright sun, as in lower light conditions, typical of the darkness of the night.

These features allow the camera to provide high video quality, very similar to the capabilities of the human eye, and offer the optical technology that ensures the application of semaphore signals across the country.
