B&W Sensors LLC is a speed detection and traffic monitoring company that utilizes state of the art, automated sensor technology to provide traffic solutions and violation assistance services to law enforcement.

The patent-pending Multiple Vehicle Speed Tracking (MVST) System uniquely monitors and records the speed of multiple vehicles in multiple lanes simultaneously regardless of whether the vehicles are moving toward or away from the sensor. The MVST System continuously calculates the speed of each vehicle based on "distance over time" inputs, which is the widely practiced method of calculating the speed of vehicles and other objects. This technology assists law enforcement who have concerns with public safety on major roadways.

B&W Sensors LLC is based in St. Louis, Missouri.
