>> How does Crowd Detect estimate occupancy?
>> It detects the number of nearby iOS devices in a property and compares it to your defined threshold. If the count is exceeded, Minut sends an alert. OK so Android users are safe, then. Woohoo! |

Wouldn't this be possible with a NUC/RaspberryPi and a bluetooth adapter? e.g. if you suddenly start seeing tons of beacons above the historical maximum, that's a good indicator. (Not trying to be "dropbox is just rsync", just commenting on the iOS only limitation) |

I'd much prefer this over a host slapping up cameras everywhere. To anyone wanting to throw parties at an airbnb, switch to Android! |

Interesting that it can only count iOS devices considering Apple is more privacy focused. What's the secret sauce that prevents Android phones being counted in the same way? |

wasn't there an algo developed that would use wifi signal as a way to detect humans / movements even behind walls. I imagine that would be a neater solution. if all what you need is a wifi receiver. |

Absolutely, maybe 15 years ago, and it was / is used by shops to detect recurring visitors and get a better understanding of their behavior. It’s also why anonymization of wifi started being pushed by Apple et al, which still does provide a stable client id but that’s only being broadcast as part of the DHCP handshake, which cannot be used here. |

I'm guessing it's because iPhones are easier to characterize over dozens of different android MAC address prefixes. But with MAC address randomization, I don't recall Apple doing anything different than other vendors so not sure what they are detecting that an Android wouldn't reveal as well. |
