From the landing page: Camera: Real-time, Accurate Break Beam: Anonymous, Accurate Density: Real-time, Anonymous, Accurate, Cheap

  Yeah, I find that claim particularly amusing since they're just using a single PIR sensor, which is far less accurate than any camera based system. There's no way that you can claim a single PIR beam is as accurate as a camera based system. There's absolutely no information on what they consider "accurate," and anything I can find on older HN threads is very vague and implies that accuracy wasn't their main focus. Here's a basic question I have: can this count a mob of 20 people walking out of store at the same time? If it can't, I believe "accuracy" should have some context, since there are other enterprise systems that do that no problem.

    > "With Density on a doorframe, we’ll tell you." The landing page advertises this as an entry-level system for doorframes. It doesn't seem that this is made for costco-level swarms of people entering a large space at one time. That said, I also have my doubts on accuracy but the error margin is probably acceptable enough to most.

    Most camera systems wouldn't accurately count the mob of 20 (I work on camera count analytics, and we have to correct for this)
