Capture and Broadcast High-quality Images from Traffic Cameras Using DVI2USB Duo
Authorities are expanding their efforts to use more efficient devices to better manage and monitor traffic as well as get real-time information. Various intelligent transportation systems are common along major arteries in urban areas. There is no wonder that their number has skyrocketed in recent years. Thousands of overhead traffic cameras and in-road traffic sensors are constantly capturing photographs, video and traffic data on major roads all over the world. This information is used by local news, national organizations and other information sources to communicate traffic status to the public. Traffic control systems help to capture and distribute traffic information as it makes driving more efficient and less frustrating. They are of great use for the emergency response teams, gather data on traffic snarls and give drivers real-time road updates.
With their capability to capture and transfer captured images from video devices, frame grabbers can be used as a part of the traffic control system. DVI2USB Duo from Epiphan Systems is capable of capturing images from any DVI source and broadcasting them over network. DVI2USB Duo is an external frame grabber that captures images at a high resolution. It uses state-of-the-art compression algorithm and the frame rate achieves 30 frames per second. It easily connects to a standalone camera through its DVI port and transfers video or snapshots for the purpose of monitoring and recording. This compact external frame grabber is ideal for all application fields where acquiring high-quality images is critical. DVI2USB Duo can capture images from either single-link or dual-link sources. It is possible to access the broadcast to view the live video from camera in a high quality. The operator in the control room is able to view live video stream from the camera – be it traffic volumes, highways surface, or weather conditions.
Traffic cameras are usually positioned at strategic locations across the trunk road network to provide an immediate view of the traffic and any incidents. When it is necessary to know the up-to-date traffic situation on motorways and roads, this solution accurately broadcasts the image from the traffic camera to which it is connected. It is possible to collect and archive data about the traffic volumes, speed and travel times. Collected information can be then collated and compiled as required to obtain an accurate picture of the current situation on the roads. Besides, using the recorded material, one can perform digital making of a real-time accident.
