Summary
[edit]DescriptionTraffic control box and surveillance system - Flickr - brewbooks.jpg |
This is the inside of one of the numerous traffic control boxes in Seattle. Long ago, these were now mechanically controlled, now they are all controlled by the Siemens computer on the second shelf. One the top shelf, the Acyclica surveillance monitoring system looks at all Wi-fi and Bluetooth signals that are nearby. It is used for traffic flow control, however, it may have other uses as well since it monitors every nearby Wi-fi and Bluetooth device. This is installed inside most traffic control boxes in Seattle, there is a circular disc antenna (labeled Skywave) on top of the traffic box that listens to the signals and feeds them to this box for collection and analysis at a central location.
