Time-of-flight Principle
The Time-of-Flight principle (ToF) is a method for measuring the distance between a sensor and an object, based on the time difference between the emission of a signal and its return to the sensor, after being reflected by an object. Various types of signals (also called carriers) can be used with the Time-of-Flight principle, the most common being sound and light. Streamax P2 sensors use light as their carrier because it is uniquely able to combine higher speed, longer range and eye-safety. By using infrared light we can ensure less signal disturbance and easier distinction from natural ambient light, resulting in the highest performing distance sensors for their given size.
(ToF) sensors of P2 measure distances using the time that it takes for photons to travel between two points, from the sensor’s emitter to a target and then back to the sensor’s receiver.

Overview
Streamax Passenger counter P2 is a professional Automatic Passenger Counter available for installation on transit vehicles including buses and rail vehicles which accurately records boarding and alighting data. Owing to its advanced technology and special design, it can adapt to different light, as well as accurately detect the entry or exit direction of passengers. Besides, user can connect the network or RS485 port to the mobile DVR, it helps operators seeking to improve the accuracy of reporting patronage as well as analyzing transit use patterns by linking boarding and alighting data with stop or station location. P2 can work as a standalone system or connect to MDVR over LAN or RS485 port for more features.
