Uni-directional traffic monitoring system

Abstract

This invention discloses a traffic monitoring system, which uses Doppler sonar to measure the direction and speed of people and object moving within a target area, such as a secure one way exit. The system is un-obtrusive, accurate, and easy to operate. In case of unauthorized movement direction, the system triggers build-in alarms, as well as signals the integrated security and surveillance systems. The system consists of Head Modules, which are responsible for sending and receiving continuous ultra-sound wave at a pre-set direction of traffic and digital processing of the data; and Management Module, which is responsible for controlling the system, as well as interfacing with other surveillance and security systems.

Dependencies are inferred from the claim text.
