Can Video Turnstile monitor busy places like underground stations?
In principle you can set up a people counting system for a train station. We have previously done this with infrared sensors, which work reasonably well, and we expect Video Turnstile to perform better. However, there are a number of considerations: • VT units would need to be placed above a zone where people transit, for example a passageway to the trains. • You couldn’t place a unit near where people are queuing or waiting (so not close to the ticket office or displays for train arrivals and departures). • We would need to know the height above the floor, because the standard cameras are set-up for floor to camera height of 2-3m. For greater distances a different lens would need to be selected. Also we would need to know the width of the passageway being monitored to estimate the number of VT units required. • The system should not be subject to sudden changes of light levels when counting many people, so the platform of an underground station may not be appropriate. • We would recom
