VP Product at aerial.ai (using similar strategies as this paper) here. A few major caveats to make this work:

a) There needs to be enough traffic happening on the network to have the resolution needed to differentiate between people. b) The device needs to be able to see the traffic. This won't protect you from a device in the home that has this technology, but it will from people standing outside of the home (as the signal attenuates a lot outside of the home)
