Consider the following situation regarding accuracy in a given moment of time:

  • A system displays a live occupancy of 9 when there are actually 10 people in a room
  • This system displays 99 visits of the same room while there were actually 100 visits

This deviation of 1 seems to have a significant impact in situation 1. However the accuracy on the total count value over time (situation 2) is 99%.

Because of this difference it is important to know in which case an optimization using a software protocol is required. When there is a possibility to control the physical situation at the entrance, the results will be improved.

In case of a maximum number of allowed people, it is common (and recommended) to apply a margin within the values, in case there is a difference between the actual situation and the digitally created situation.
