VISIO WAY

OpenCounter allows areas to be configured over the field of view. Areas function as video detectors as vehicles pass over them. These video detectors can be of the following types:

• Vehicle Presence Detectors: These are activated while a vehicle is stopped in the area or circulating over it. These detectors provide data on the number of vehicles and the time they occupy the area.
• Tracking Detectors: These detectors discriminate between directions of circulation and can be used to detect traffic violations (illegal turns and drivers circulating in the wrong direction).
• Traffic Jam Detectors: These detectors are activated when vehicles are stopped in an area, occupying a configurable percentage of the area.

Each vehicle presence detector can be associated with a digital output that can be directly connected to other equipment such as a traffic light controller, these connections are similar those found in detectors of different technologies (infrareds, inductive loops, laser...)

Traffic jam detectors or traffic violations can also generate outputs when a situation for which each detector is programmed is produced. These outputs can act over other external devices or be communicated to a traffic light controller in order to modify its performance.

The equipment uses its non-volatile memory (Secure Digital Card) to store information concerning each area over a configurable period of time. These registers can be accessed by a control center or by a laptop computer (OpenCounter has an Ethernet connection).

The system contains a embedded LINUX in addition to what has been installed:

• A html/php server: This allows the equipment to be configured from a laptop computer or from a control center, using only a web browser (Firefox, Internet Explorer,...).
• A video server: This transmits MPEG4 digital streaming video taken in real time, in a way that it can be visualized using a viewer such as Mplayer or similar.
• FTP Client: This allows the server to automatically upgrade new versions.
