1. A system comprising:
a first positional sensing device configured to monitor a first area comprising: a pulse generator for generating pulses;
a sensor for measuring reflections of the pulses generated by the pulse generator and reflected from one or more detected objects;
a first module for determining positional data for the one or more detected objects based on the reflections;
a server remote from the first positional sensing device wherein the server is communicatively coupled to the first positional sensing device via a network, the server being configured to:
receive the positional data for the one or more detected objects from the first positional sensing device; and
determine a trajectory for each of the one or more detected objects through the first area based on the positional data.
