| > The 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 service. The "order" button just brings up a blank email. Might I add that if there's no privacy polity, the FTC won't go after you for violating it. And the company is new, so this stuff is "tomorrow" kind of stuff. They have the limelight for right now; might as well use it. > How does the device tell how many people are present based on counting at a doorframe? Is it counting people passing through the door? Does it detect direction? Is it good enough to estimate the number of people inside by subtracting out counts from in counts? Doesn't seem so. Looks like they're going for the niche between mom-and-pop to something smaller than Staples. > Will this work for wide entrances, such as malls? Is this a passive infrared sensor? Those go blind in hot weather. PIR doesn't die due to hot weather. They go blind in heavy humidity. They start throwing errors and bounces around 40% and up. Here in Indiana, they would be nigh useless right now, unless inside AC. > This looks like a cheaper alternative to video counting systems, of which there are many. Video systems get about 98% count accuracy. I'm working on that. I've gotten better than 98% already. My time is "make it better and sell it". > If you already have surveillance cameras, you can often use them for counting. That's my point. Most/all businesses already have it. So the whole creep and privacy factor is a moot point. Might as well leverage the tech you already have installed. |
