How does the solution handle multi-ingress/egress points?
Could it be used for tracking population leaving during a fire drill? As often this is the first question asked by first responders, "Is anyone still inside?"
This would be a reallly cool application if PIR's were capable of counting "horde" foot traffic, like a giant mass of people streaming out of a door during an alarm. I don't think that something like a PIR could handle that number of people, since it's just the single beam.
