- guscost 6y agoDensity (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.
- james412 6y agoVery cool!
- guscost 6y agoThank 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.
- dexterdog 6y agoWhy 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?
- PragmaticPulp 6y agoMost OSes and devices randomize MAC addresses during scans to prevent this: https://en.wikipedia.org/wiki/MAC_spoofing#MAC_Address_Randomization_in_WiFi https://en.wikipedia.org/wiki/MAC_spoofing#MAC_Address_Rando... It's also not guaranteed that every person is carrying a phone or that their phone is turned on.
