Had no idea what this was. Clicked link. Within one minute I figured out what Density is. Nice job on the landing page! IMO, this is the strongest section:…
robotnoises on HNFantastic product idea and a landing page that's so good that I figured out what the product does without touching my scroll wheel. I wish however, you'd include a section that…

Useful data for businesses and retailers
From 2 comments
I would say it's extremely useful -- most establishments have a general idea of foot traffic (ie: POS transactions or qualitative visual assessment) whereas with density.io you…
ihsw on HNI own a retail store and have been wanting this type of data to quantify behavior, find correlations and discover patterns. In it's simplest form, it could help to quantify…

Objections
Subscription model criticized and no privacy policy
From 3 comments
Why does this need to connect to your servers? What happens if you become insolvent? Why can't I just buy the damn thing then use it? Why do I have to pay for a subscription to a…
tyho on HNThe site is rather vague. They provide the hardware and install it for free, which implies they're selling data to someone else. Who? There's no privacy policy. No terms of…
Animats on HNLooks like an awesome product and hardware but the SAAS model sucks (for us). Here's to hoping they release a LAN model for a one time fee.

watty on HNAny plans to offer a "disconnected" version where I could push this data to my own aggregator+API instance? Use case for me would be where foot traffic numbers would itself be…

Questions
How does the sensor determine direction and handle groups
From 3 comments
I was also wondering about its ability to determine the direction of traffic. If it relies on a location having a separate entrance and exit, that's a pretty big negative. I'm…
noxryan on HNI spoke with Andrew over at density.io. His answers regarding can it see the traffic direction (answer - yes for each individual) and how it is powered (custom length power…
Smushman on HN> It can determine traffic direction; which is a leap beyond current technology i.e. a break beam, which cannot. all it would take is two or more beams and some pretty simple…
