MAXIMUM accuracy depends on used sensors and can be up to 98-99%.
PRACTICAL accuracy depends on lightingconditions, local circumstances and visitorflow density and -behaviour.
NEEDED accuracy depends on your business and possibilities for improvement.
A guarantueed accuracy is suspicious! Accurracy is strongly depending on local circumstances like:
*Density of footfall\ visiotrs flow
*wideness of entrance
*height of measurement (horizontal systems)
Measuring more accurate then needed drives up costs. Measuring less accurate then needed is a waste.. ask us for advice!
