Andrew Farah, Density

This week, Sixteen:Nine speaks with Andrew Farah, the CEO and one of the founders of Density, a San Francisco-area start-up that's going at crowd tracking in a different way.

Density puts a small sensor at the doorway or doorways leading into a venue or a targeted area,uses infrared beams to measure anonymous movements as people come and go, and generates real-time and historical data that can be integrated into different devices and systems, like digital signage networks.

The attraction to digital signage network operators is that it can do accurate crowd counting without using camera-based video analytics, which can get expensive and tends to freak out some consumers and privacy advocates.

In simple terms, what it means is an airport could have digital displays that show security screening wait times, based on crowd density, at different screening areas (and load-balance crowds who will likely go to the lines that are faster). It could also be used for things like telling consumers if tables are free at popular restaurants.

Interesting chat. Well worth a listen.
