Tolerance / Accuracy of multiple people moving past People Counter
Q: What is the tolerance / accuracy of the People Counter if multiple people walk past the counter as a group?
A: The People Counters feature a horizontal infra-red beam - so each time the beam is broken it increases the count. The more narrow the entrance/exit, the more accurate the infra-red technology becomes. For example, a counter installed at a 1 metre entrance/exit will be very accurate, because people usually pass through 1 meter entrances/exits in a single file fashion. On the other hand, a counter installed at a 3 meter entrance/exit can be less accurate, because there is more room for people to pass through the entrance/exit simultaneously. If two people pass through and break the infra-red beam simultaneously, the count will only increase by 1.
To test the tolerance/accuracy within your environment you can request a trial unit for a small fee to cover delivery & insurance.
