Density (software) engineer here. Our sensor uses active infrared lasers to read depth, and it classifies "persons" with a deep-learning algorithm that runs on the device.
Why not just scan for MAC addresses? Legal reasons? Can't you black box something like that and not safe the actual IDs but use them for unique counting?
Thank you, I agree! My focus is mainly on the parts downstream from all of this, once counts & count deltas can be uploaded to the cloud. When I joined, the focus on advanced hardware, anonymity/privacy, and edge-computing all struck me as very forward-thinking, and it's been really cool to see the product mature and find its market in the past couple of years.
