X-Stream

Virtual loop on video technology

TrafiCam x-stream is an integrated camera and detector offering vehicle presence detection and MPEG-4 image compression.

This intelligent system provides detection and monitoring of moving and stationary vehicles at signalized intersections. Via detection
outputs, vehicle presence information is transmitted to the traffic controller so that signal timing can be adjusted dynamically, resulting in reduced waiting time, improved traffic flow and less pollution.

TrafiCam x-stream is an IP-addressable video detection camera. Streaming video at full frame rate is available via Ethernet for system and traffic monitoring. Users can configure, view and control the system both on-site and remotely.

The system setup is quick-and-easy: a userfriendly PC tool allows connecting to all TrafiCam x-stream devices on the network. A camera image is available for accurate and fast positioning of the presence detection zones. Making the system operational is done in only a few minutes.

TrafiCam x-stream is a cost-effective and reliable solution that offers all benefits of video detection. This is an above-ground system without expensive installation and maintenance costs, typical for traditional inductive loops.

TrafiCam x-stream is based on field-proven video detection technology and is part of the La Semaforica product range.
